21′ Classic Sloop Day-boat

21' Classic Sloop Day Boat

The Roeboats Classic 21′ Sloop Dayboat is based on a hull design recorded by William Atkin in the late 1940s. It’s a beautifully balanced hull with a plumb stem and a modest reminiscent of 19th century boats and a shaoe that evolved to suit the dichotomy of good speed and sea keeping ability rather than to satisfy a racing rule as was later the case at the beginning of the 20th century.

These hulls originally had two rigs for summer and winter use. The summer rig was a single massive cat boat rig which was needed for the light airs of the summer. The winter rig was more versatile and easier handled to suit a variety of conditions. The rig illustrated is a gunter rig of 210 ft² with a self tacking jib. There are many advantages to this rig including: Low stress on the rigging, small easily handled spars and perhaps the most  important for a boat that will be easily towed to far flung cruising grounds short spars that fit inside the hull.

Also the mast does not project beyond the transom of the boat when lowered in the tabernacle and so all standing rigging etc. can remain in place for traileing.
