Noob here. Looking at a Seaforth 24

Discussion in ' Sailboats ' started by TCieszki , Feb 14, 2014 .

TCieszki Junior Member

Hello all. I am new here but not to sailing. I have owned a Hunter 28.5, Sanbel 19, and Prairie 32. I currently live aboard a Hunter 30 and also sail a Com-pac 16 (with beautiful Tan Bark sails) in and around Titusville, FL. I am interested in adding a Seaforth 24 to the "fleet". Anyone tell me more about this pocket cruiser blue water boat? Tnx, Terry  

Petros Senior Member

this one? there are others that would know more than me, but based on the hull lines I would say it would be a roomy pocket cruiser, but rather slow. Likely sea kindly as well, it looks heavy and very strong. It was described as a coastal cruiser, but I think by the looks of it it would make a decent open water boat if good preparations and certain precautions were taken.  

PAR Yacht Designer/Builder

Yep, you've surmised correctly, Petros, she's a well burdened little cruiser. She's easily twice as hefty as a other 17' LWL yachts at 4,200 lbs. and her D/L of 380 and SA/D in the low 13's suggests she'll do well in trade winds, and storms, but not much else. In her defense, she does carry a 38% ballast ratio, which is respectful for her general class. She'll track like a freight train, but backing down will prove a challenge, except to the prop walk side. She's built down quite a bit, so with heavy angles of heel, she'll lose most all of her effective lateral area. She should have a comfortable motion in a rough slosh and the forefoot is cut back enough, that tacking will occur with reasonable confidence. She's a bit small to be considered a blue water boat, though easily a cat. B, but she's better suited than many coastal cruisers. Your Folk Boat will be a faster and similar companion, but your Hunters and Sanbel will eat it up on every point.Speaking of a comparison, your Sanbel has a 17' 10" LWL and displaces about 1,400 lbs., half the D/L and nearly twice the SA/D, so . . .  

Tnx, guys. I appreciate the replies. (didn't think I could reply.... main screen said invalid). I was hoping I got the one-lung diesel in it but got the outboard. Cosmetic re-fit needed but a sound boat. At 22 feet (advertised as 24) I don't expect to be using the "passing lane" much but I am sure it will get to where it's going. Tnx agn. TTC  

Yes, Petros, that is the one. Sailrite also calls it a 22 in their sail plan data. It is possible Seaforth calls it a 24 because of the bow roller (anchor) and whatever they call the wooden thingy that holds the backstay out. Those two items could make it a 24. With the generous freeboard, hopefully I can keep the greenwaters off the decks! Tnx. TTC  

Well, I bought the Seaforth! I am now prepping it for off-shore use. The weight/length ratio is 381, so it certainly is heavy enough. Anyone have off-shore time on the Seaforth 24? TTC

Seaforth for sale! Well, as nice as the boat is, I was able to rebuy the Prairie I owned in '02. My efforts will now be aimed at reffiting the "tub". TTC  

Is there a online site for a noobie sailer to lean a bit?

Where is she now?: 76' Frers MAXI, Xargo IV (renamed , built of aluminum at Palmer Johnson

Where is she now peppermint patti, nelson/marek 1/4 tonner built by betts, where is she now norwegian steam, half-tonner from -80 designed by eivind amble, where is she now: pendragon iii one-tonner (ior=30.5) designed by laurie davidson.

where should the widest part of a sailboat be?

Is it a total loss or is there something worth saving

Review of Seaforth 24

Basic specs..

The boat is typically equipped with a Renault RC8D diesel engine.

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 Seaforth 24 is 1.81, 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 5.5 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 Seaforth 24 is about 77 kg/cm, alternatively 433 lbs/inch. Meaning: if you load 77 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 433 lbs cargo on the boat it will sink 1 inch.

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)

“ I just received my asymmetrical spinnaker, with sock and turtle bag, along with a new 135 Genoa. The entire process was simple and both sales and the design team were in regular contact if there were any questions. The customer portal was easy to use and lets you keep track of where in the process your sails are. Great sails, great service -Graham Edwards (Facebook)

“ The whole team at Precision Sails was fantastic from start to finish. We’ve had a laminate main and genoa made so far and have a spinnaker on the way. They listened carefully to our needs and recommended a great sail cloth. We couldn’t have gotten more bang for our buck! -Noah Regelous (Google)

“ We received our spinnaker and launched it yesterday and I just wanted to let you know how pleased we are with it. The service we received from your company was exceptional and the quality of your product is second to none. We will certainly be return customers in the next few months to replace our main and jib sails and will recommend your company to all our sailing buddies. Once again-thank you.” -Daniel Jackson (Google)

“ we had good communication during the planning stages and the knowledgeable people at precision sails really got me fixed up good! The sails look and work fabulous! my boat sails better than it ever had! couldn’t be more pleased with the product AND the service!” -Fred Jelich (Facebook)

“ Our new furling jib for a Corsair 27 Had to be specially designed due to the height of the furler, but this was accomplished quickly and in short order we had our sail which fits beautifully and has a great shape. It’s everything we could have wanted, high tech design, thoughtfully executed and affordable.” -Nancy Y. (Yelp)
