20' plus...great idea. (hiding these boats is easy)
115 hp...even better idea.
CC...best idea. (will keep you dry in the spray)
With 6 to 8 trips to the east, you'll be glad to have the bigger boat, and the added floor space and storage.
I have a 2070 Crestliner w/ SC with Yam 115.. It has served me well, but I still wish I had something like a 20' Maycraft CC.
With a lay-out boat, Seaduck rigs, Full array of Divers, and Puddle duck decoys. 3 to 4 hunters and their gear, and 2 or 3 dogs, even a 20' boat can get crowded quick. Good luck with new boat. Also, if you can wait, their will be some bargains in February after season ends.
