Personally I would buy something with a bit of shelter,
like a Redbay 7.4+, fitted with a inboard Diesel. The difference that you would have being out of the weather in immense, you would go out and play in any type of weather instead of getting soaked or all wrapped up in drysuits etc (just waiting for the flames
The diesel would give you reliability and also an easy fuel to buy, anywhere that there are fishing boats you will buy fuel or even in the worst case from a Farmer. Diesels are generally speaking far more reliable, and you can always usually make a temp repair to get you moving again......so long as its not a catastouphoic (sp) failure.
I looked at a 8.4m with canopy etc and quite a good electronics package, boat was about a 2001-2 for around £35k. It also had a good trailer and was fitted with twin Styer inboards driving through a Bravo 1-2 leg.
