Inflatable thwart seat

[claretcass]

I have just purchased a 60cm grey inflatable thwart seat for my dinghy. It is pretty standard being shaped like a circular tube rounded at each end with a Halkey Roberts adaptor for inflating. No instructions so what pressure do you inflate to? Is it the same as tubes maximum 2.9 -3.2psi or just until comfortable to sit on?
Thanks for any information.

Inflate the dinghy, put the seat in, inflate it til it doesn't move when you sit on it.

Rock hard works best for rowing.

Many thanks for the information

Depends on how big your bum is.

Large, very LARGE....I will blow it up to 25psi and work back from that....

That is as much as I put in my van tyres.

I am looking for an inflatable thwart for a Wetline 320 RIG Dinghy. With the tubes pumped up I reckon the gap for the thwart between tubes is around 69cm I can only find 60cm long ones and I don't expect over inflating will make up the 9cm difference. Does anyone here know where else I could look please?
Many thanks
Steve

I have a takacat inflatable cat, which comes supplied with a cylindrical inflatable thwart, similar to that described. It also has Halkey Roberts valve, and recommended pressure is 3 psi max. I find that too hard for me, and reduce it slightly. You may be able to get one from Ribs marine, Christchurch, Dorset, who are importers
