Avon Redstart: Aft seat dimensions?

[NigelBirch]

Does anyone have the dimensions of the aft seat for an avon redstart? I need to make a new one and forgot to measure it last time on the boat.

Thanks

Did you ever get back to measure it? I am now in the same situation and wanted to make one too.

I have a Redstart and there is no aft seat ... an inflated centre one yes. Sure you have right model ?

The Redstart and Crest are round tail inflatables .... didn't know a seat could be had for aft in one. Unless someone made up one from board ?
