Hi Rob,
I am not sure if I should post questions to you on my design via
private email, or the forum. Since there aren't any specific structure
or finance questions, I thought I would try here.
1) What is the "best" beam clearance for a harry-sized boat? I figure
2' min and 3' max. The higher, the more force on the rudders. The
lower, the more wave impact. What do you think?
2) Does a bit of rocker help? If I am going to go with carved foam for
the "front" 25% of the hull, I could give the hull a little rocker as
easiliy as not. Would that help turning? If so, should I then lengthen
the ww hull to give it a better length/beam ratio?
3) I have drawn the ww and lw hull with as small a beam as I think I
can get away with.. 20" for ww and 12" for lw. Increasing that beam a
little will give me a better walkway in the ww hull and easier access
into the lw hull. If I increase to 22" ww and 18" lw, will I be giving
up significant speed?
4) I read in your harrigami papers that you put a bulkhead 26" back
and (I think) carved the last 2 feet of bow out of foam. Is that the
recommended procedure, or do I bring the foam sandwich forward as far
as possible and just round off the bow?
5) Cutouts for hatches - do I cut these out of the foam before
infusion, or do I make solid panels and then cut the hatches into it
after assembling the panels into a boat?
6) How do I know if the sail plan I drew up will really work? Is this
calculated, or do you just have an "eye" for it? I am particularly
referring to the use of the screacher on the extended jib boom.
Thanks,
- Gardner
