RE: [bolger] Fiberglass sheathing for a reduction in the number o f ribs I have to bend
My two bits...
We built a 16 foot strip canoe using 1/4 inch strips without the benefit of
bead and cove (which, as I found on another project, really stiffen up the
hull). Our only bracing comes from the narrow centre thwart, the two seats
and the gunwales. I think the Herreschoff you refer to could also be built
without frames beyond a pair of frames at each seat position, which would
support the seat and add some strength to the chine joint at the same time.
(For what its worth, the book (Hazen) we built the canoe out of also had a
20 foot freight canoe built the same way, with no more bracing than ours.)
The Herreschoff looks like a nice boat -- good luck!

Subject: [bolger] Fiberglass sheathing for a reduction in the number of
ribs I have to bend
I am presently in the process of building a form for a Herreshoff 17
foot row boat as shown in Gardner's "Building Classic Smallcraft."
The boat is double-ended with approximately 16 inches of beam at
bottom and 48 inches at the sheer. The method shown in the book is
bent ribs (approximately 5/8"x5/8") at eight (8) inches on center
with lapstrake sides of 1/4" plywood. I am planning on using 1/4
inch cove and bead cedar strips with 6 oz glass on the outside and
either 4 or 6 ounce on the inside. Due the added strength of the
fiberglass I would like to reduce the number of ribs, but still
retain a considerable amount of strength and rigidity in the hull.
As a minimum I will install ribs at the twart and oarlock stations.
Does anyone have any thoughts, opinions, or recommendations on what a
suitable rule-of-thumb might be for the trade off between fiberglass
sheating and ribs.
