I think Cash Bar had the best quote for that comparison:
I still say the most amazing part of the day was watching that 43' Sunsation running smoothe as glass at 85 or so on the first leg.....no BS.
I think the F4 is a better looking boat than the 43V but that is just my biased opinion. I know Mark and Eileen's new 43 V tags 100 with triple 650's and the F4 Powerboat tested hit 99.2 with a pair of 700 Mercs.
Nortech has a good dealer/ factory for Florida but Sunsation has several nationwide. Anyone here can call Sunsation Monday-Saturday at 6 am and talk to one of the owners. Company has been around since 1982 and has unbeatable customer service. I bought the my 32 and I had never heard of the company before! The F4 would be on my short list but Rob your 39V is one of the sharpest NT's out there!
