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.

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

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.

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.

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).

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.

For sailing downwind the design may be equipped with a spinnaker.

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