Thanks for all your feedback and suggestions guys, keep it coming
Yea jockey seat is a must as the bench seat provides little support and you can't stand up with it but I will leave it in for when other people come out on the calmer days.
@Pete7 I have tried it out and found it to be bow light, but do you think moving the console a metre or so forward and moving the fuel tank will affect the balance enough to do without ballast?
Yea my parents used to have an osprey sparrowhawk that they used for diving around Ireland and it was a terrific boat aswell.
@stul Was it actual trim tabs you fitted or hydrofoils on the cavitation plate? Which one do you guys think is better - bearing in mind how expensive trim tabs are?
Also if you could please help me out, I've started a thread entitled securing console/seat to the deck. If you have a chance check it out and give me a few pointers - http://rib.net/forum/showthread.php?t=24880
