Review of Etap 26

Basic specs..

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.

The boat can enter even shallow marinas as the draft is just about 0.95 - 1.05 meter (3.12 - 3.42 ft) dependent on the load. See immersion rate below.

Etap 26 is typically equipped with an inboard engine at 10.0 hp (7 kW).

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 Etap 26 is 2.10, indicating that this boat would not be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Etap 26 is about 142 kg/cm, alternatively 799 lbs/inch. Meaning: if you load 142 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 799 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 L/B (Length Beam Ratio)?

What is a Ballast Ratio?

SA/D (Sail Area Displacement ratio) Indicates how fast the boat is in light wind: - Cruising Boats have ratios 10-15 - Cruiser-Racers have ratios 16-20 - Racers have ratios above 20 - High-Performance Racers have ratios above 24 Sail-area/displacement ratio (SA/D ratio): 21.01

The ETAP 26 is a Belgian trailerable sailboat that was designed by E. G. van de Stadt as a cruiser and first built in 1982. [1] [2] [3]

• 1 Production
• 3 Operational history
• 5 References
• 6 External links

The design was built by ETAP Yachting in Belgium between 1982 and 1989, with 500 boats completed, but it is now out of production. [1] [3] [4]

The ETAP 26 is a recreational keelboat , built predominantly of glassfibre, with wood trim. It has a fractional sloop rig, a raked stem, plumb transom , an internally mounted spade-type rudder controlled by a tiller and a lifting keel. It displaces 5,084 lb (2,306 kg) and carries 1,568 lb (711 kg) of ballast. [1] [3]

The boat has a draft of 5.25 ft (1.60 m) with the lifting keel extended and 3.11 ft (0.95 m) with it retracted, allowing ground transportation on a trailer . [1]

The boat is fitted with an inboard engine with a saildrive for docking and manoeuvring. The fuel tank holds 7 U.S. gallons (26 L; 5.8 imp gal). [1] [3] [5]

The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin and two straight settee quarter berths in the main cabin with a drop-leaf table that allows one to be converted to a double berth. The galley is located on the port side just forward of the companionway ladder. The galley is L-shaped and is equipped with a two-burner stove, an icebox and a sink. A navigation station is amidships, on the starboard side. The head is located just aft of the bow cabin. [1] [3] [5]

For sailing downwind the design may be equipped with a spinnaker . [1] [3]

The design has a hull speed of 6.24 kn (11.56 km/h). [3]

Operational history

The boat was at one time supported by a class club, the ETAP Owners Association . [6]

A 2009 review in Yachting Monthly stated, "the largest of the lifting-keel Etaps, launched in 1981, the 26 manages a proper heads compartment amidships and an inboard engine powering a saildrive. She is designed to right herself with the keel fully up, but many owners tend to sail with it permanently down, because the mechanism for lifting this large chunk of ballast manually requires a good 15 minutes of winch-grinding at the foot of the mast. Some 26s have an electric servo motor to relieve this burden. The deck-stepped 7/8 fractional rig has sweptback spreaders and an adjustable backstay. All sail controls are led back to the cockpit. She is fast and commendably stiff under sail, and goes well to windward with a tacking angle of 75-80°, but needs to be sailed fairly flat to avoid weather helm. She has an unusual cabin layout, dictated by the large lifting keel. The chart table is at the forward end of the saloon and the navigator is obliged to work sitting sideways-on. She has four sea-going berths, or potentially five at anchor: two straight settees in the saloon, one of which converts to a double, and a vee-berth in the forepeak." [5]

The Etap 28 is a 27.62ft masthead sloop designed by E. G. van de Stadt and built in fiberglass by Etap Yachting between 1978 and 1987.

375 units have been built..

The Etap 28 is a moderate weight sailboat which is slightly under powered. It is stable / stiff and has a low righting capability if capsized. It is best suited as a day-boat.

Etap 23 is a 24 ′ 2 ″ / 7.4 m monohull sailboat designed by Jacques De Ridder and built by Etap Yachting between 1982 and 1989.

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)
