a mistake or what else

[thedog]

I have a guy interested in my 23 cc, I have had it for two years now and have worked out all of the bugs and it is perfect, this guy comes along and is willing to pay for a finished product. but now the dilemma , the 23 runs like the devil, and I have been looking to get into something bigger, in the 31 ft category
granted I don't think a bigger boat will run any smoother or in any tougher conditions than the seacraft, more room and making day trips 80 miles off is the reason for getting something bigger. now do I take the deal and expect to fish offshore more. or keep the 23 and fish offshore with it
how much better would a 31 run than the 23 in most conditions.
keep it simple and keep what I have, or open up a new can of worms with another boat
this is going to beat me up.
