Endurance 35

• August 5, 2009

The ketch-rigged Endurance 35 has the typical hallmarks of the range: fl ush deck with doghouse, boomed staysail and, on some boats, a stub bowsprit. The hull is long-keeled and full-bodied, allowing plenty of internal volume. She has a wood or glassfi bre doghouse, which provides full headroom in the after part of the saloon but the deckhead is low further forward. The standard arrangement offered six to seven berths in three cabins with a good galley and a large navigation area. She is not particularly close-winded and needs a good breeze to get going, but handles well and can plough on through weather that would send fl imsier craft scurrying for the nearest bolt-hole.

Does anyone know much of those boats? The hull and displacement would suggest very seaworthy. Any experiences? http://www.networkyachtbrokers.co.uk/boats_for_sale/Endurance_35-1011018.html/  

They are just how they look. Steady, sturdy and comfortable. Were very popular in their day for dreamers as they were mostly home built of ferro, although some were built on hulls from Windboats. Inevitably though that means hige variations in quality of construction and fitout with price range to match. The one in the ad will be near top of the range, but you can get them for very little money. some later boats were built with GRP hulls. Despite their physical size, rather cramped down below compared with more modern designs. The 40' version, although not so common is a much bigger boat and better in every way for more than 2 people. If you are restricting yourself to a 35' or lower end of the price range arguably there are other better boats of the type for the money, such as a Voyager 35. As an aside ferro boats of doubtful provenance are very difficult to insure, although a Windboats hull and good history and survey will probably be OK.

Nice to look at certainly, but a tad cramped below & with a short waterline and long overhangs, they are somewhat slow and are very fond of pitching. Watch out for water tanks that use the hull as one/two sides of the tank, often prone to osmosis from the inside out. Also, adding circa 1 ton to the bottom of the keel really helps with performance.

rptb1 said: I liked the shape and deck plan of the Endurance, and so I looked at dozens of them in the past ten years, thinking of long distance cruising and living aboard. I've only seen one with a decent interior, and that was "Peel Piper", at Hamble I think. View attachment 35894 I still love the lines, but I reckon you'll have a project with most of them.

Pitchpole?  

Not sure why it would be more prone to pitch poling or tripping over its keel than other designs. I would be inclined to say that would indicate an issue with ballast distribution.

Marsupial said: like many long keel boats they don't slide down the side of a large wave, the keel digs in and the boat rolls over. It "trips over its keel" Click to expand...

TiggerToo said: aha! that negates all the stuff people write about long keels being the bees' knees for long distance / high seas cruising, then. Click to expand...

robmcg said: Bit of a Job's choice then. Long keeled that won't surf so could pitch pole v light weight that may broach spectacularly and wipe you out. Click to expand...

I just been on one. I didn't like the layout. One double cabin forward of the saloon. But to get to the forepeaK cabin and the heads you need to go via the main cabin, no privacy for those sleeping there.

Belliure Endurance 35

Belliure Endurance 35 is a 35 ′ 3 ″ / 10.8 m monohull sailboat designed by Peter A. Ibold and built by Belliure Yachts starting in 1975.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Sea Turtle IV

A very rare opportunity to acquire a proven rugged offshore vessel recently returned from a 10 year circumnavigation. Meticulously maintained by knowledgeable and fastidious owners who have just completed a comprehensive refit. Everything is clean, clean, clean. Sea Turtle is now ready to cast off and go again to any corner of the globe you choose!  Almost new Beta diesel, wind generator, solar panels, water-maker, autopilot, wind steering and SSB with Pactor.  Its all here. Its all ready to go.

Sea Turtle with the current owners have been awarded numerous Blue Water Cruising Association awards and have completed over 50,000 NM of blue water cruising.  They and Sea Turtle have visited some of the most distant and exotic ports of the world during their10 year meandering circumnavigation, well documented in their blog.

The Endurance 35 design by Peter Ibold won the “Best Cruising Design” award several years in a row and resulted in hundreds being manufactured around the world. DeKleer Bros in Vancouver built over 65 Endurances here on West Coast, but only 3 Center Cockpit Offshore models. Rugged, beefed up and customized, they are very serious blue-water cruisers. The comfortable and iconic Endurance design can be seen in most far-flung ports and anchorages of the world and dozens of standard Endurances have circumnavigated. Endurances are iconic long distance cruisers with a highly respected offshore reputation.

Endurance 35.

17 comments:

Well, what a coincidence that this should come up in late July 2011 as I browse the web as a break from boatyard work! We have a De Kleer Brothers fiberglas Endurance that we finished from a bare hull in 1979-85, and have sailed in BC and offshore (US/Mexico/Hawaii/BC again) for a couple of years in the late 80s. De Kleers built a lot of these hulls in the Vancouver area. I don't know that Spencer Yachts did build the boats--perhaps if they had a custom division they finished a hull or two on a contract basis from De Kleer hulls. The fiberglas layup on these is bulletproof! She's a great boat, perfect for a couple. Ours is rigged just like Unicornio above. We are currently installing a bowthruster--she has many good qualities, but turning on a dime is not one of them--the long bow overhang means she will blow off, if the wind is in the wrong place, particularly in close quarters such as docking. We are really looking forward to the Lewmar bowthruster! In other respects--sea-kindly, comfortable, and pretty as anything! Kathy BC, Canada

Kathy is correct. The De Kleer brothers built the boat here starting around 1974. I knew a guy who built one of the first hulls - they hadn't even finished the deck mould when he bought his hull. The Spencer connection is very tenuous. Someone on Vancouver Island bought up a number of obsolete moulds from defunct local builders, including a couple of Spencers - in the 90's IIRC - and branded themselves Spencer Yachts. To the best of my knowledge they never produced any Endurances from the old De Kleer moulds.

Kathy - thanks for your comments, we had a bow thruster, fitted by the previous owner too close to the waterline, at anchor with conditions that caused any kind of pitching there would be a "glug, slurp, glug" noise coming from the fore peak. Good luck with your boat

Hi, I am french.. I owned the proper Peter Ibold's Endurance in the 80'. Built in ferrocement by Windboats Ltd.. Very pleasant boat. I sail now with a catamaran, but nearly i will be looking after another... Endurance 35 ! :) Best regards Guy

Guy, A bit late but are you still looking to buy an Enmdurance? Please contact me via [email protected] (Holland)

Hi, my wife and I have a ketch rigged Endurance 35 built in ferro by windboats, she very friendly in rough weather and needs a decent blow to get the best out of her, marinas are always fun she has a real mind of her own, you sometimes think your getting good at handling her then she will do something compleatly different, we would never change her, great boat with loads of space and will take you any where!!

I juust buy an endurance 35 ferro-cement,,, reliable boat , 1982 bilt in frech , and been around the world for 15 yeras , and the forgotted until 3 yeras ago,,, now its in my hand and i have saild it brasilian cost , 13 days for 1250 miles with 2 days of stormy weather against , would like to find some pictures about interior so i can make this boat better as it needs care thankz arvin

Another Smart post from you Admin :)

My father and I scratch built an Endurance 35 in 1972 & launched in 1975 from plans purchased from Peter Ibold. We built a male mold on a stongback in our backyard from the offsets. We covered it with 2 x 1/4" diagonal plywood strips above the waterline & 2 x 1/8" diagonal hardboard strips below the waterline, then glassed over the whole thing. It's 5/16" glass on the topsides and 5/8" glass under water which is doubled over the keel for a 1 1/4" stem. We dragged the hull out into the alley to turn it right side up with a couple of wooden arches bolted to one side and a couple of turfers. We pulled the hardboard out below the waterline and added additional glass for the 5/8" thickness. We left the 1/2" of diagonal plywood above the waterline for stiffness and insulation and added a couple of layers of glass inside for a bit of a sandwich effect. It is a very stiff yet light hull. Finished with 7000lbs lead ballast and 40hp French 'Bernard' V4 air-cooled diesel. She sails very well (cutter rig) and can point very well. All in all a very well behaved cruising boat that can hold her own in any conditions. BTW. I'm currently building a 1/12 scale RC model from the plans. I had build a 1/24th scale model from a female mold I built when we were building her, but I gave that away years ago. I'm building this one a little larger for better sailing performance.

Do you still have your plans? Could I get a copy of them?

I have a cutter rigged De Kleer built Endurance 35 in Toronto, though it still has "Victoria BC" lettered on the stern. The previous owner apparently had it up and down the east and west coasts of North America without major problems. I bought it in 2011 for about $50K, and have replaced the original "Suzi" (Izuzzu) with a brand new 38 HP Yanmar diesel, added a new binnacle guard and NavPod and all new electronics and auto pilot and stereo, and two new battery banks of 2 super 8D AGMs for a total of 1,100 ah, and a new mastervolt 3x50a smart charger , among other tweeks. Plus lots of costemtioc work. Upcoming projects are to replace the old 80's vintage solar panels, add two wind gennies, convert the old fiberglass built in water and fuel tanks 2x40 water, 2 x 25 fuel) to diesel bladder inserts (for total of 130 gallons diesel capacity), a watermaker and new plastic water tank, radar, AIS, EPERB, life-raft, new sails and rigging (fed to cockpit), etc, to prepare for a retirement partial circumnavigation. I love the way she sails! She is not fast by any means, but when it is blowing, we are often the only boat out on the lake, and we can reef down and head to weather under all conditions we have encountered to date. She takes large waves with ease as she slices right through them with her weight, full keel and reserve buoyancy in the bow and stern (unlike many modern boats I have chartered that tend to slam their flat bottoms over waves and shake your teeth loose (along with cabinets, fixtures and bulkheads!) He best point of sail seems to be just slightly off the wind, but from close hauled to a beam reach I can balance the sails and do not need to use the autopilot at all. She has a furling Yankee, a club footed staysail with one set of reef points, and a main with double reef points, all in tanbark. Will probably replace with white sails, reefing furling Yankee, with a furling staysail on the jib boom, and a standard main, with all functions led back to the cockpit, as I am getting on in years and am not so surefooted on the foredeck as I used to be.

Good day all, I am wondering if there was any hull ID # on these boats and where would it (they) be? thank you, Al

Hello everyone. There is a Facebook group for Endurance owners and anyone else interested in these fine boats to share photos and information etc. please feel free to join, just search for Endurance owners group. cheers!

I am owner of a 1988 De Kleer Endurance, and am interested in finding an owners group. I have searched Facebook for their owners group, and find none. Could you post a link if it still exists?

Hi, I just found the group under "Endurance Yacht Owners Group". Have a nice day.

Hello Everyone, We have a Belliure 35 version of this lovely design, built in Spain. She is a little old at 1978 but fairly solid. Not the fastest boat in the world but then why hurry something you love doing. Concur with comments regarding manoeuvring in marinas, different every time. We have the cutter rigged ketch version which offers lots of flexibility but have yet to try her out in heavy weather. The power unit is a Volvo 2040 which does enough, and we are slowly upgrading bits of the interior and electronics. We always get interest from other people in harbours, partly because they are worried we will crash into them and partly because they love to see a fine old boat. Always interested to hear from others. Matt

Thinking of buying one to go cruising with my wife and 8 year old.Would the Endurance 35 have sufficient space? Also Ferro or Grp. Thanks. Any feed back would be appreciated

endurance 35 plans

• Add to quote

I'll start by saying hey, and thank you for all the great info, this is my first post. At the moment I have a Santana 22 and am looking for an upgrade, after much deliberation I've come to the conclusion that the best fit may be building my own boat (it sounds crazy I know). ferro sounds like the best option, since I'm no expert welder. I love the look of the endurance 35 ( https://sailboatdata.com/sailboat/endurance-35-belliure ), but have not been able to dig up the plans. I know they are out there as I've seen some pictures in ads for the boat ( Endurance 35 purjevene 1988 - Turku - Nettivene ), but they are all outdated and in different languages, so no luck contacting the sellers. I also realize the designer, Peter Ibold has past away, so no chance of contacting him. If anyone has any input or ideas on the whereabouts I would love to hear! I'm also not set in stone on the endurance design too, open to suggestions, but i need something that has ferro plans, preferably with a pilot house as I live in the pacific northwest. 35 feet is as big as Im willing to go and the lower the draft the better. thank you -Bryce  

I would have to recommend that you stay away from Ferro boats. they just don't work out very well. the material does not hold up as well as the designers will tell you and now that the material has been around for many years we see proof of this all the time. the boats have very low resale value and most do not sail very well. partly because they are built to very old sailboat designs and some just plain bad designs. also just does not make since to build a boat today with all the very inexpensive boats available on the used market. the money it cost today to build a 35' boat is going to be 5 time the price of a good used boat even after you refit the boat it will still cost a least twice. there is no way you can build a capable 35' cruiser for less then 150K. if you are building because you want to build then fine but if you are building to to have a bigger boat to sail then buyy a used boat and fix it up, you will be dollars ahead and many years ahead also. Sorry to bust your bubble about Ferro boat but they are not that good and can even be dangerous.  

thanks for the input overbored, I understand these boats are in no way equal to glass, but it's not just the finished project that excites me. I am definitely keeping an eye out for the right kind of "project" in my area. From what I've seen these boats get a bad reputation from poor build quality but there are a lot of solid ones out there. I see your point, but i'm going to try and keep an open mind to ferro for now.  

There have been some pretty strong boats made using plywood covered with fiberglass. I know this isn't the question you were asking, but, don't build a boat unless you like building more than sailing. You won't save time or money.  

I understand where you are coming from . many many days ago I was involved with a Ferro project, as time went on and the project never seeming to get close to being finished My life moved on to other projects and the owner bought a new fiberglass boat to sail and he said the deciding factor was that he went sailing on another ferro boat of the same design and his take away was that the sailing qualities of the boat were not good. by the time he had done all this work and time moved on the new fiberglass boats designs were a cut above any of the designs offered in Ferro. Yes there are some solid boats made of Ferro but how old is the design and how do they sail. The other factor is the material does not lend it to inspection of the structure. the internal metal reinforcing structure does rust and break down over time and can not be inspected without cutting into the material. so you are always guessing how how long until it fails. like some of the early homebuilt aircraft wings that used wooden spars that were glassed into a wing and the wood could not be inspected after it was built, they have a use by date. Have friend with a Ferro boat that he is has been fixing up for the last year going on ten years now. the cost of the special hull coating he has just purchased would buy a really nice fiberglass boat. the other sad thing is even when he gets it in the water it is a design from the 60's and is also known to be a sailing pig. not only is it not fast but it is so slow you need to have GPS just to tell if you are moving. if when pointing you are into saiing sideways then it is a great boat. we tried sailing the boat when he just got it and he said he was going to haul it and fix a few things. he was 60 then and now aa 70 he still is not sailing his boat but goes with us on occasion.  

I think I see what your saying, I just wish there were some more modern designs for ferro boats, but i guess there is a reason for that, (they don't work as well). Again it's about the build as well, i could see myself working on a glass boat to some degree, but when building my own boat i know exactly what's going on and problem spots, no mysteries. If I can find the plans for the endurance, i figure there's a reason that hundreds were build, many from ferro.  

I owned and chartered a ferro Endurance 40 for seven years in the Med’ in the 1980’s. It was a fairly slow cruising boat, but very sea kindly in rough weather or the choppy seas of the Med’. I never had a single spot of trouble with it, but then it was a Lloyds certified hull from Windboats, in Wroxham, England. I visited the Belliurre yard in Calpe many times, and I can attest to their workmanship and quality, but they didn’t do ferro hulls when I knew them. All this was a long time ago, and I didn’t even know Peter had died. It might take some web searching, but I’m sure you could find some drawings of the 35 somewhere. If you can find a Windboats ferro hull I think it would still be sound, provided it’s not been damaged. A survey, by a Ferro surveyor, would definitely be in order. JR

Review of Endurance 35

Basic specs..

The Endurance 35 is equipped with a long keel. A long keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

The boat can enter most marinas as the draft is just about 1.52 - 1.62 meter (4.99 - 5.29 ft) dependent on the load. See immersion rate below.

Endurance 35 is typically equipped with an engine.

The fuel tank has a capacity of 269 liters (71 US gallons, 59 imperial gallons).

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Endurance 35 is 1.66, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.9 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Endurance 35 is about 182 kg/cm, alternatively 1020 lbs/inch. Meaning: if you load 182 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1020 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

What is SA/D (Sail Area Displacement ratio)?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 20m 2 (215 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.
