320cms and 40kgs. The reason i askis there is one for sale in good condition and its a lot cheaper than a zodiac futura. The 350 vib i have does about 18mph one up with my 15hp which seems to me to be on the slow side compared to what others are achieving. Hull is inflated to correct pressure. When going onto full power the revs on the engine drop (got a tiny tach) and i think its because the floor flexes so badly altering the planing surface. I realise this is another air deck but would the shorter length and speed tubes make a great difference or would i be better off getting a solid floor model. Just crave that extra bit of speed and sure the engine the can provide that with a more efficient hull.
been looking at these inflatables for a while, seem quite good build quality, speed tubes for better handling and quite light for a fold away. nearly bought one from roche marine to use with my 18hp tohatsu s/s, but have been informed you need l/s motor cos of the speed tubes. anybody got any 1st hand performance stats on these sibs ,ie speed, handling, floor flex etc
