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.
