A slight back story - I am now within 60 days of making a boat purchase which is part of a 2 1/2 year process. I initially narrowed my search down to the 400 Sedan Bridge and found one with three cabins (which I really would like to have). Just before I took my wife to a sea trial with me, we stopped and looked at a 420 Aft cabin. Needless to say, we are now in the market for the aft cabin. I have a few questions for anyone who may know: Changing out the carpet. Is this difficult to replace? We have found several boats that are cheaper but the carpet looks horrible. Any gotcha's to look for? I'm aware of the problems with the 3116 Cats. Cruise speed, hull speed and fuel burns would be nice. I'm figuring around 20-25 gph at 20 kts? Thanks all and Happy New Year.
