Can anyone reccomend the correct pressure to inflate to for this particular dinghy? David I think it's the mkII that you mentioned in this thread earlier, the one with the 55hp rating. Would it at all be possible to get a copy of your instruction manual for this boat? Obviously I would be more than happy to cover any costs. Thanks prairie tuber I was worried it was going to be pvc it feels quite a bit lighter than our old ex MOD boat, though that has been painted, has oversize tubes, tons of patches and I'm guessing is a thicker material.
