My bases are genuine MP and are 'as new'. It sounds as if there's some base abuse going on here. ;-). Or in Boggy's case, bass abuse 'coz he's bored of sheep. :-D

Clearly yours doesn't get in the water enough, ours where already green and furry when we got the boat!

Ok, I heard you the first time! Partly true, and also, your bases were made of shit material. I could leave mine on a swinging mooring for a year and I very much doubt if my bases would rot.

Our marine ply bases rotted after about 5 seasons on swing mooring and non closed cell foam.

Just had new "modern" man made ones with closed cell foam.

Closed cell foam? I thought the idea was open cell foam so that water could pass straight through rather than soaking into the cells of the foam?

I always thought that the idea of closed cell foam was that it does not soak up water.

That is the other 'issue' with my seats from day 1 is that if the boat is out in the weather for a while, when you sit on them you are sitting on a giant sponge and the water scooshes out = wet ar$e if launching in jeans! As it now lives under cover that is not an issue but I still need to take the seat cushions off to let it air out in the garage otherwise the seat pods go mouldy inside.

A proper seat cushion with a rigid base made out of some sort of plastic material and waterproof closed-cell foam for the cushion would be the answer.

I have no idea whether the ply on mine is marine ply or not - but it was certainly untreated on the visible side. It looked like the stuff I'm building a house with at the moment (what is sold as 'exterior ply') but the seats were one of several finishing touches which weren't really up to the quality of the underlying hull. Good to see it has moved forwards.

Another question while we're talking about progress: on the jockey console, water on the console always runs down the front of the cushion and into the under-seat void as there is no form of sealing where the cushion sits on the console. I tried adding a strip of sticky backed door seal along the front for the seat cushion to seal onto, but it comes off too easily. Does the current model of this seat have a seal or different arrangement for the cushion fixing to keep the water from getting in? It's not a lot, but again in heavy rain or when washing it down you get some water ingress.

I agree with Kerny. Motorbikes use closed cell foam too I believe.

The trouble with closed cell foam is that it doesn't stay closed with use. It breaks down and allows water in, but doesn't allow it out.

That's what I understood
