I have just bought a Portofino 31. I'd be interested in talking to other owners about their experiences specifically top speed, prop size, trim etc.

Re: we\'re not not speaking to you...
..just that there ain't enuf of of us to have a quorum of PortoFino owners round'ere. In fact, you're the expert and we bet it goes like stink! 40 knots in the book means 38 knots more like 35 with antifoul and gear. A sunseeker dealer in the uk will praps introduce you to other owners. A sunseeker dealer in the Med will introduce you to other owners and a severe drink problem.

You probably have explained why I can't get much more than 30 knots out of it. That an the halfwit french guy I bought it of fitted a forward & side looking depthsounder with a transducer the size of a small football to the bottem of a streamlined deep V hull.
My first big boat so I am still learning !!

Re: boats not reaching spec speed
Talking of which, does that apply to all boats? I mean, is it the case that all boats somehow never quite reach the speed in the brochure? From my limited experience of say half a dozen boats, I reckon all boats are 2-3 knots off the brochure speed, then knock off some more for clean antifoul, more still for dirty antifoul, plus some for ropecutters, then the weight of crew and toys etc etc. Does everyone else find the same?

Re: boats not reaching spec speed
Yes. Two categories :
First is that (for example T48) some examples are *miles* offtheir target speed. There's a T48 in mallorca for charter which the bloke says can only do 24-25 knots. F did a deal withim, and it's still chugging around.
Second is as you say, not making the speed at all. I *did* go in a t48 which made 34 knots on so'ton water with 8 on at the boat show. After 4 years I found out how to do it.
1. Leave boat on dry land for a few months
2. Clean, Antifoul
3. Don't put much water or diesel in
4. Thrash downwind with gps on for Quite Some Time
Five mins at top tilt and we saw 36 +knots, with brief flashes of 37-39. It won't do it once the boat has been in the water for more than a week.
