Building my first SOF kayak.....
I'm sure to make some mistakes, leading me to constructing another boat...and another, quite likely.
I am constructing my strongback at present. I bought 3 2X4X12 and 1 5/4X6X12, all Pressure-Treated.
I had to do this because it's quite likely my strongback will have to live in the weather. I don't have a garage or storage shed long enough to take it. This will likely be the same fate of the 'yak, as well.
All of which leads me to two possible ways to address this.
Knowing that cedar is rot resistant, not rot-proof, and no natural wood is rot proof- encapsulate with epoxy, or start with a material that can take exposure to the elements for a good long time in the first place.. pressure-treated wood.
Yes, I am aware that SOF construction doesn't need epoxy, is beautiful on it's own merits, etc... and I agree. But if I can use modern materials to supplement this (with the obvious caveat of let's not make it into a moonshot) and increase the durability of the project- why wouldn't I?
Obviously the boat will be heavier.
A quick google search shows us SYP 2X4X8 is about 1.28lbs/linear foot... so 10-1/4 pounds (10 pounds, 4 ounces)
Treated is about 15% heavier. Of course this all depends on species of lumber, etc...
Yes, the weight difference will be substantial- about 3 pounds, maybe more. I'm still going to have a darn light boat- and to be blunt, the first thing I need to work on lightening is my arse- and I'm doing that...
I won't be able to store the boat indoors ( I live in Charleston, SC, so frost really shouldn't be a concern). I realize that there will be a UV concern with the coating. I'm ok with having to redo the finish now and again (although, I may have a solution to avoid that, too).
The point of this is to find out if a SOF is worth doing to a high-end level (all cedar, etc) when it won't be able to be "babied". It'll be strapped to my fence in the back yard (basically, a kayak rack) year round.
