The "Alegra"
- a multi-purpose dinghy.

Principal dimensions:

	L.O.A.      3.35 m  (10' 11.8")
	Beam       1.475 m    (4' 10 ")
	Sail area    5.0 m2   (54 sqft). 

I designed this dinghy originally to be an alternative tender for my yacht. The ply/epoxy "Alegra" weighs only about 48kg/105lb, whereas my aluminum tender is a more hefty 78kg/172lb. Your yacht would have to be flush decked for stowing her on the foredeck.

I can see her also as a super family fun boat to take to a lake near your home, where you can let your kids learn to sail.

She is safe and stable, has buoyancy compartments in the enclosed aft side-seats and the forepeak.

Sails:
I have designed and tested a few rigs for this dinghy. You can use most any mast and dinghy sail easily available.

Just mail me the dimensions and I will check on suitability and balance and suggest how to rig it up. The sprit rig and the triangular 'leg-o-mutton' sail are two suggestions to show what can be used.

A free-standing mast would be my first choice to avoid rigging wire etc.

Here are a few pictures of the Alegra sailing with a fairly large sail. This is a gunter gaff rig, which keeps spars short.

Recently I came up with an experimental sail based on a jib. See Experimental sail for "Alegra"

Propulsion:
Alegra is long and slim enough to row easily. It is always a pleasure to row quietly to and from the yacht, so I recommend fitting rowlocks at the mid thwart.

For longer hauls of course an outboard can be fitted. The transom height is suitable for a short shaft outboard motor.
Power: 2-6 HP, max. 9.9HP.

Hull shape:
"Alegra" is of the single chine type, but with the addition of a flat keel strake, which improves the hull shape, making it closer to a double chine form. Beneficial is also that the flatness of the keel panel makes joining of the daggerboard case and fitting of the mast step easier.

Only a little extra work is required compared to a pure single chine shape:

There is the keel panel to cut out and one more seam needs taping as in effect there are now two keels joints.

A good example of the flat keel strake can be seen in Piccolo built in California - this link takes you to some very interesting pics of a recently completed boat.
