My Scantlings

Engineering Scantlings

I have given good reviews to the engineering in unreadable engineering books.
I have given good reviews with reservations to scantlings for large wood strip boats in various books.
I have given poor reviews to scantlings for canoes and kayaks in all wood strip canoe and kayak building books.

I now offer a booklet of my engineering scantlings for sale:

about 38 8-1/2"x11" pages.
Design rules for wood core / cloth epoxy face construction valid

for displacements from 100 pounds to 600 pounds,
for when you can overpower the wind and water and for when you cannot,
for E-glass, S-glass, carbon, and Kevlar 49 fibers in plain and satin cloth, and
for hulls, decks, bulkheads, coamings, seams, and paddles.

Engineering analysis.
Strength Optimals.
No building techniques.

Cash or a check for $40 sent by US mail to the address at the bottom will get you a copy of my engineering scantlings sent by mail. US orders only.

Power Scantling

I have given poor reviews to software that computes drag on boat hulls.

I now offer a booklet of my power scantlings for sale:

about 18 8-1/2"x11" pages.
Design rules for hulls based on power output

for touring and racing
for displacements from 100 pounds to 600 pounds.

Engineering analysis.
Excel spreadsheet that does power computations
Formula for one of the most efficient hulls if not the most efficient.

in a comparison to 64 production hulls our racing hull finished first.
in the same comparison our touring hull finished first among the touring hulls and in the top 10 overall.

Cash or a check for $25 sent by US mail to the address at the bottom will get you a copy of my power scantlings sent by mail. US orders only.
