The issue with more power is with the mixed ability of the people who will be opperating the rib.
Which is afterall why we converted from twinn 55s to the single.
Yes a 70 fourstroke would be ideal but we're a small sailing club and finance like that is not easy to come by.
Blocked up the holes today and fitted a bilge pump.
Fitted the vhf and checked the regulator and the charging system.
Messed around with the cable adjustment for ages trying to get neutral, reverse/forward in the correct place and think I got there in the end.
Went for a blast down the coast and all seemed fine.
On the sea she felt far better than she felt on the high speed section of river.
Hand held GPS says 24knts compared to the twin setup which we saw 36knts.
So in terms of speed and the sort of use she'll have I think performance is about right.
That said, I think that the engine might need flattening out a little as she tends to go nose high and at around 4-6knts she throws out a big wash.
I think that she'd benefit from a finer prop especially when we have to tow dingies in and out of the harbour.
However like a fool I forgot to check what prop we have - I'll do that tomorrow.
Thanks for all the help thus far.
