Am thinking of some upgrades / changes to the boat for 2010...but am struggling getting realistic (or any) ideas of the performance change I will see.
My current top end is around 43 knots.
I have already sealed off all unused hull fittings and reduced weight (though I am obviously not going to get down to some of the displacements I see on other boats here
!!!). I can lose maybe another few hundred kilos here and there.
The only upgrade that seems to make sense at the moment is Lab finish & cup props at £60 a blade from Steel Developments....12 blades £720 (ex VAT)....though Steel Developments won't be drawn on what sort of performance gain I might see, they'll only commit to "...this should give you an increase in top speed..."
Any ideas????
Other (more exotic) ideas include
surface drives (though Arneson also won't suggest a performance target...and finding ASD8 in the UK or even US second hand is a struggle) and/or
re-engining ....though I won't do this until my Yanmars die. I will then go for 440hp Yanmars or 480hp Mercruisers with either surface drives or NXT drives if I go Mercruiser....though both these options are years away though and I want to squeeze what I can from some tactical changes to the current set up....
