I may be building a K1 eventually and will be striving for the best strength I can get in a VERY light kayak. I need to do some calculations to see if I can match the weight of the production K1 boats. I am thinking king 1/8" strip and the thin glass with as little resin as possible, I just might make a competitive kayak for my kids.

It is possible to build a strip built K1 to match the weight of production kayaks.

This one is only a whisker above the minimum legal weight for a marathon K1 of 8kg. That weight includes the polystyrene block for floatation, the seat, footrest, tiller bar and rudder. If it was any lighter then technically I would need to carry ballast.

It is made almost exclusively from Paulownia, which is about 20% lighter than WRC, so that saves about 10% or about 3/4kg on the total weight. An identical WRC K1 would weigh about 8.75kg.

The strips are 3.5mm thick because that was the thickness of the WRC used for accent strips. I was given a lot of WRC venetian blind slats.

The glass is 85gsm inside and out. That is about 3oz.

In the last year, I have competed in ten races in the NSW marathon series, used it for close to one hundred social paddles and even managed a few dozen training paddles, so it has done about 1500km and it still looks almost new. The only tiny scuff marks on it happened carrying it through the gate to put it on the car. So it is quite strong enough.
