Many thanks chaps - very helpful and no I had missed that thread re buying a used RIB
Okay have now seen one I like the look off but before annoying the seller further thought I'd seek opinion here.
It is a 5.4m Searider, ex customs, Suzuki 65hp with electric trim and tilt and Self righting equipment
Seems a genuine sale - no storage space and family grown up - he's owned it since 2001
I don't think it's anyone from Ribnet - but apologies if you are :-)
I've seen the discussion re the eBay 5.4m so not sure on the price for this one
Many thanks as ever
