Length of Strongback?

Post by GraMac » Sat Jan 20, 2018 10:40 am

Just about to dive head first in to my first ever canoe build – I have, after much deliberation, chosen the Cottage Cruiser.
Forgive the nativity of my question but, how long should the Strongback be for a 15’6” canoe.
Many thanks.

It will depend on how you cut your forms !

If you cut them so the stems are above the base line, and your forms resemble mushrooms. Make it as long as the canoe, or even longer.

I cut my forms so the stems are below the base line. This Is how I got started, It saves a lot of plywood, when cutting form. But requires the strongback to be matched to the length, of the design.

So in general terms. My forms require a strongback to be roughly 16" shorter than the canoe I'm building ..

Hope that helps !

I think 16’ is pretty much the standard length ... if you don’t have copy ofCanoeCraft, ithas a lot of this info, including the plans for the stronback. may be worth grabbing a copy.

Build it 16' and cut your forms so they are above the strongback. You can build it easily out of 8' sheets of plywood (see Canoecraft as Brian suggests).

You shouldn't custom build your strongback for your (first) canoe. You'll need it for the next canoe you build (you can't stop at just one).
