Winchelsea 2.2
Loa 2.26m (7’ – 6”)
Beam 1.19m (3’ – 11”)
Draft 0.127m (0’ – 5”)
Dry Weight 22.5kgs (50lbs)
Maximum Load: 500lb (227kg)
Crew: 2 Adults
The Winchelsea 2.2 is available as a kit and as DIY plans. It is a little smaller than the Winchelsea 8 and the planks can be cut from a standard sheet of 2.44m x 1.22m plywood - no scarfing required. It is different from its larger sister as it does not have a long keel which is replaced by a flat keel plank onto which a length of timber and a skeg are fitted. The open edge of the stem is capped with thin strips of wood that are carefully bent round to join at the keel. The flat keel plank makes for an easier build but it is still built in the same way - over a mould. However, it could be built using stitch & tape if you don’t mind the stitch holes. If you’re painting your hull inside and out, this is not a problem but, if you want to varnish your hull then I wouldn’t use it.
Available as digital or A3 Workshop plans or plans with Full Size patterns (8 x A0 sheets of plank, bottom, stem, transom and frame templates).
Basic Materials Required
Plywood – 2 sheets of 6mm exterior or marine grade for the hull, 1 sheet of 9mm or 12mm ply for the mould, transom and the seats, for the knees and breast hook. Solid timber lengths for the sheer trim 2.4m or longer. (The mould can be made from 12mm chipboard or MDF as a possibly cheaper option). 4.5kg Epoxy pack

Winchelsea 8
Loa 2.44m (8’ – 0”)
Beam 1.168m (3’ – 10”)
Draft 0.152m (0’ – 6”)
Dry Weight 30kgs (65lbs) Rowing Version
Maximum Load: 500lb (227kg)
Crew: 2 Adults
The "WINCHELSEA" rowing/sailing dinghy. 8' - 0" x 3' - 10" and a dry weight of around 80lbs (36kgs). These are the original plans for this boat as I originally designed it - a multi chine clinker style dinghy that has a variety of uses. It has a keel piece instead of the keel plank to give a more traditional appearance. It can be rowed, sailed or motored and is a sturdy little vessel. The plans also include the sailing rig details. The size of this boat means you can't get the length of the planks from a single sheet of plywood so you have to "scarf" (join) a small piece to 4 of the 6 planks. Full details in the plans.
Available as digital or A3 Workshop plans or plans with Full Size patterns (10 x A0 or large sheets of plank, bottom, stem, transom and frame templates).
Basic Materials Required
2 sheets of 6mm exterior or marine grade for the hull, 1 sheet of 12mm ply for the moulds and keel/centre frame, plus half a sheet of 9mm or 12mm for the seats, knees and breast hook, or solid 18mm thick timber to fit, The moulds can be made from 12mm chipboard or MDF as a possibly cheaper option. Then the keel can be made up from a smaller sheet of 12mm ply although still 2.4m in length.

Winchelsea 10
Loa 3.04m (10’ – 0”)

Draft 0.178m (0’ – 7”)
Apprx. Dry Weight 39kgs (85lbs) Rowing Version
Maximum Load: 700lb (317kg)
Crew: 2/3 Adults
These plans are for the "WINCHELSEA 10". The pictures above show two great examples from first time builders. A very similar looking larger version of her 8’ sister, continuing with the clinker style hull, 6 planks per side, multi-purpose Rowing/Motor or Sailing dinghy that can be used as a tender to a yacht or larger vessel or for a day of fun on the local water. She is 10’ - 0" in length, 4’ - 6" beam and designed to be as light as possible for her size and construction. Although she could be carried on the roof rack of a large car, she is far more suited to a small trailer. She will also take a small lightweight outboard 2hp - 3.5hp for motoring up and down the local river, canal, harbour or around the local lake. Electric outboards are an option with this boat too. The plans detail the transom outboard pad to add strength. Built in buoyancy bags can be added by enclosing the seats or fitting inflatable buoyancy bags. The plans are available for a rowing/motor or full sailing version or you could build to rowing/motor standard now and add the sail rig later.
Available as digital or A3 Workshop plans or plans with Full Size patterns (10 x A0 or large sheets of plank, bottom, stem, transom and frame templates).
Basic Materials Required
3 sheets of 6mm exterior or marine grade for the hull, 1 1/2 sheets of 12mm ply for the moulds and keel/centre frame (unless using 18mm) and transom, plus half a sheet of 9mm or 12mm for the seats, knees and breast hook, or solid timber to fit 6kg Epoxy pack

Dry Weight 64kgs (140lbs)
These plans are for the "WINCHELSEA 12" now has full size patterns and is easier to build with a keel plank instead of a long keel. The A3 plans will keep the long keel for now as some people prefer it.
Still very similar looking larger version of her 8’ sister, continuing with the clinker style hull, 6 planks per side, multi-purpose Rowing/Motor or Sailing dinghy that can be used as a tender to a yacht or larger vessel or for a day of fun on the local water. She is 12’ - 6" in length, 5’ - 0" beam with an approximate dry weight of around 140lbs (64kgs). Not really suitable to be carried on a roof rack, she is easily trailed and launched. She will also take an outboard 2.5hp - 3.5hp for motoring up and down the local river, canal, harbour or around the local lake. Electric outboards are an option with this boat too. The plans detail the transom outboard pad to add strength. Built in buoyancy can be added by enclosing the seats or fit inflatable buoyancy bags. The plans are available for a rowing/motor version. The plans include the details on how to adapt a rig that would suit this boat and a Mirror dinghy has been adapted to this hull.
Available as digital or A3 Workshop plans or plans with Full Size patterns (14 x A0 sheets of plank, bottom, stem, transom and frame templates).
Basic Materials Required
6 x sheets of 6mm exterior or marine grade for the hull, 1 1/2 sheets of 12mm ply for the moulds and transom, plus a sheet of 9mm or 12mm for the seats, knees and breast hook, or solid timber to fit, (The moulds will become the seat supports.
