I haven't been there since I was a kid but that place is HUGE. I have a friend that spends a lot of time at his grandparents place. I was asking him about smallies recently and he was like oh ya we kill it. I'm not sure about your boat on that lake though
Bobby, I would not hesitate to bring your cartopper. There are dozens of smaller BOW withing a 30 minute ride, some a LOT less of Sebago. The bass fishing is amazing. I have a book at home that has a list of lakes and ponds, their size and what species are in them and where the access points are. Let me look for it tonight and if I find it you are welcome to borrow it or photocopy some pages if you like.
Sebago is huge, crystal clear and can be TOUGH. The smaller connecting ponds like Long lake and Brandy pond are smaller and IMO fish better with a good mix of LM and SM
