Hull Design

Getting on the Plane

The main difference between Raedwald and other similar traditional, clinker style dinghies is her ability to plane.
Her lightweight construction, and flat mid sections, mean she will be able to accelerate over her own bow wave, even in a modest breeze, and skim across the surface of the water.
Planing can be an exhilarating ride, but the pressure of the water flowing faster under the hull actually makes the boat more stable and easier to control.

Being able to sail fast downwind has other advantages too, such as reducing the apparent wind strength, and hence the load on the rig. It also makes the boat easier to gybe, as there is less weight in the sails.

Cutwater

A plumb stem maximises waterline length, and allows for an extremely fine entry.

This increases the hull speed in sub-planing conditions, reduces drag at all speeds. It also means the boat will not lose as much momentum, cutting into waves, in choppy conditions.

The way the bow parts the water generates a lot of grip in the water, improving the upwind performance. It also affects the flow over the rest of the hull, so it is extremely important that it is as smooth and sharp as possible.
The hull shape quickly flares into very full shoulders, with enough buoyancy to ensure the bow could never be submerged in normal conditions.

Plenty of freeboard

The shape of the hull, particularly above the waterline, can trace its Lineage back to 'barge boats', an essential part of any Thames Sailing Barges equipment.
