Throw the old pig-iron away and buy a couple of nice, shiney outboards?

I have a similar ratio and can sit at full throttle in appropriate conditions without any problems - except fuel consumption. Why am I not having the same problem?

Bruce.
Don't go looking for any more problems, you seem to have had more than your fair share already.

Very interesting discussion I've now got a better understanding of the different RIB designs out there. With my setup I think I'm at 125HP/Ton if it only weights 184KG empty which would indicate I am underpowered especially once I add ballast. What type of load should I strap to the bow, about 80KG? My sponsons are barely touching the water at the transom. I'd like to get a Searider 6+M eventually then I won't be bobbing around like a cork as much. Still a great little boat for now though.

Our leisure boat is about 180hp per ton and the raceboat is 210hp per ton - that is both without fuel ..............

just think... the amount of combined time spent writing and reading all this- you could have been out on the water feeling the waves skip merrily below (or around) your tubes rather than trying to imagine it.

Just food for thought...

What I dont understand is how y'all dont fall out of the ribs in Australia - what with being upside down on the bottom of the earth....
