James, drove a 6.5m with Opti 150 for a weekend on a boat handling course weekend before last. Quite impressed, well built and nicely finished. I now have the Tohatsu version which is the same design just slightly older.
At rest the tubes don't touch the water when they are lightly loaded (4 ppl) which is how they get the good performance from the hull. Handled the Solent chop well and gave a great feeling of confidence. Wasn't keen on the Optimax throttle control box which was as always awful. Given a choice I would much prefer the top mount "commander" type of controls even at the extra expense.
Suprisingly the course boat didn't have an elephants trunk to drain the hull, although the owner did say he didn't like them therefore assume he requested a boat without it. This was a mistake as a 3/4" pump is nothing like as effective as a 3" elephants trunk when it really matters.
Thanks for the info Pete.
I think i will go for the 6m cause i have already got a new 135 optimax really cheap, and its just a question of find the right boat for it! The 135 on the 6.5m i fear may be a bit too slow for my liking, so the 6m seems more reasonable.
Go for a drive in one first before you settle for the smaller hull, if you can get away with it that 50cm will make a difference to comfort and handling. Would you like to have a drive in my 6.5m ? do you a swop for a days plastering in me new house
