if going new
sea search 390 heavy duty 25 hp max 5 man max 68 kg weight £935.00 new two year warranty Ron hale marine.
i would go for an heavy duty boat for fishing
plus loads of other boats with a decent write up on each
If you're considering new, and considering paying up to a grand then seriously look at the Honwave boats, highly regarded as one of the better brands and I'm certainly very happy with my 3.8 which I bought here last year:
I bought a yam 3.83 in 2001 and married it up with a mariner 25 two stroke.
She was great and still going string today I believe. took four divers on short runs, plenty of hours on safety covers and pulling toys, had loads of fun and thought she was a great toy.
I think the condition will dictate if the one you are looking at is a rubbish build or a better one.
Others have mentioned honwaves, I personally like the Quicksilver range of sibs but which ever one you go for make sure it'll do what you want, not what we think is best.
