Driving force yes, but negative.
Experiment with a (stern hung) fabric rudder migh be in place before a keel..
Basaltex in Belgia I've used.. very good experience with them. ps. Basalt is also easier to laminate, it wets out epoxy resin much better...
I made one like this. Stripplanked bottom, sides 10mm divinycel but could be done strips also 300gsm biax/epoxy on all surfaces. Lifting keel,...
The buttock angles make the main difference on close and over hull speeds where the vessel is moving from dispalement speeds to semi planning. Bow...
Too much concluded only by the entry angle and a single speed. Hull forms are totally different. Buttock 1/4 angle plays way more on 9kn than entry..
Another method which allows more complex forms. Wood strips layed as base grid, fabric stapled over, plaster to form final "mold". Laminate over...
My pick would be 10mm Divinycel. Cut to stripes narrow enough to follow the curve..
For wood (and ply or OSB) it's easier, faster and better, I've done both CSM/Poly and Biax/epoxy so know the difference. Even if epoxy costs more...
Forget CSM, use 600gsm Biaxial with epoxy. You end up stronger laminate with much less material used. Read Gougeon Brothers book before starting,...
It's not that. All biaxial, triaxial, uni, wowen, twill etc are without binders and compatible with epoxy. Chopped strand matt is always with binder..
The right side sample might be from the end of the roll so not a good sample..
Did you notice any difference on resin amount you used on those two? Looking those samples makes me think the one on the left you get better...
Not by trade but "involved" in boat building since childhood and as a hobby afterwards. Aside that building a hull is straight forward work as...
Yes, lofting and setup included. I made the bulkheads after the deck was in place so concur about the bevels and curves, but eventually with...
Repurposing when it's viable. In Northern Norway old wood boats have been used as sheep shelters upside down. A plastic one could hold longer.....
Have you checked the weight? It might be heavier just labeled wrong..
Sorry to hear that.. Not even on private shore property?
Spring tide, wait a few days, do the work, refloat.. That's how it's done in my whereabouts.
I collected lead from shooting ranges and one old keel of derelict boat. Costs mostly some diesel to collect the stuff and 1k € for moving that...
