20 footers is where it is right now. I would venture to say it will continue with that same trend. The P4 seems to have a very specialized market and it serves that purpose very well. Judd Lasiter
Judd has answered your question on the Bass Cat sizes for the most part. The sales of Bass Cat boats revolves around the 20 mark for the most part in 2008. 2009 will move more to an 18 and 19 foot market, though 20 models will still rule that area.
So if you were going to get a boat to run for a year and then sale, what is the best size to cover the market. I personally like the 20ft size, but would be happy with a 19ft boat if I thought it would cover the market better.
