The minimum draft
Snapdragon:
In regards to the sailboat: A draft of 6' is an absolute "No-Go" for us, so is a full keel. The shallower the draft the better. Our Ovni with its lifting rudder and centerboard changed our cruising lives for the better immensely and I am not going back. Also, I do not want a sailboat or a boat without active stabilizers.
. But while they are optimized for the speed I desire, they are not efficient.
for us it was only the right choice for our type of cruise.
Like to go in some place with very shallow water.
After our schooner Damien II (not a lifting keel only centerboard model 1.60m) we built in Vietnam a 17.40m lod ketch motor sailor twin engine the draft of the hull is 1.35m half of the ballast in the center board half in the bottom of the hull.
After that built our "passagemaker" Long-Cours 62, (same designer for the hull line than the Damien, Vietnam built : Joubert),
we said to Joubert : flat bottom to stand on alone, low consumption, below 5 m width, minimum draft (hull 1.12cm, ruder 1.30m , could be 1.13 if 2 rudder) for us it was the perfect boat : very low consumption, basic K.I.S.S. boat.
Unfortunately even if we sold our actual boat we will not able to built a new "near " similar one even smaller because the price to built hull now $$$and we are now really too old to start again a built one by ourself :-(
even, if all owner of boat, I play to design the "next one" smaller (because $$$, one engine because $$$, less alloy (10 in place of 12, 8 in place of 10) because ... yes $, but even it is too expensive for us .
For example a member of this site contacted us and he said for an hull of 8200kg he got a quotation of....378000€ only the hull !! It means 42€for kg of in a finish hull ? ! In 20 year the price for an empty hull increase by more than 500% !? more than 8.35% per year ? I don't know your salary but in France clearly they don't follow this curve
:lol:
And also the "raw" material alloy don't
