Thread: Iki Waa three years on

    Default Iki Waa three years on

    Iki Waa is a 12 x 30 open canoe which was built lightly and cheaply and without some of extra work and expense of similar craft.

    I thought therefore it would be worth reporting how he has survived three years of abuse.

    A bit about the build
    4mm quality 3 ply ply (Robbins Elite BS1088)
    Canoe has fore and aft and side to side symmetry with ply internal and external ply butt joints all in line at the centre line
    Chines internal fillet and covered with 50mm glass tape, peel ply used
    No external tape on chines, keel coat with 25mm Kevlar tape. Outside chine area coated with epoxy to seal edges and minimal filling.
    Inside bottom where the panel is wide coated with 200g carbon, I had some lying about.
    So no epoxy encapsulation painted the big shed primer and gloss couple of coats of each.

    As a shell Iki Waa weighs in at 13kg, 28kg to which an off the shelf SOT seat and buoyancy bags.

    The abuse, Iki Waa has been down mild rapids, bounced off rocks and down weirs. I have thrown him about a fair bit with the focus on use rather than care. He has also be converted to two variants of sailing canoe and further stressed as this development progressed. He is kept inside a garage.

    So how has Iki Waa survived three years. A few scratches and dings on the bottom but very superficial and not through the first laminate of the plywood. The bow keel area did wear the Kevlar a bit (running up beach and portage dragging) and a 3mm stainless rod has been epoxied in. I have touched the outside a couple of times and he looks as good as new, which was a working finish.

    No structural issues or anything worry about the long term durability of the canoe

    Interesting read. Just goes to show that as long as you use good quality marine ply (like BS1088) there's no need for an epoxy coating. I can never understand people's desire to smother good wood with all this epoxy stuff. And after that comment, I await any flak!

    They believe the hype is the answer but if you boat spends most of its time in a dry garage epoxy is unnecessary in my opinion.

    Sun light is the most damaging environment from my experience and epoxy isnt UV stable. I listened to an interview of a classic boat wooden mast maker a bit ago. He thought the idea of epoxy coating was potty.

    Epoxy is awesome as a glue but for coating Im still to be convinced. Part the problem is it very much cheaper in the USA so lots of books have been written where it is the norm and peoples just follow.

    What does this mean? Does she weigh 13kg or 28kg?

    Yep, obviously it is only small which helps a lot and others may have spent hours getting it perfectly fair and added lots of filler, but the work boat finish works for me.

    The lightness also comes from not tapping the inside and not coating it in epoxy which as a build method hasnt let me down.
