. They have a fenced marina and lots of people keep boats on shore there.One thing about keeping your boat at the dock - you have to account for rain and weather. A good storm can swamp a 12ft tinny, even at the marina. The last thing you want is to get to the dock and see your motor under water! You can get one of those auto-pumps for under $40, but then you need a battery, which has to be kept charged etc etc...
I agree with the above posts that a trailer really opens up fishing possibilities. You can tow it with just about anything too.
Do you know anyone that lives on the bodies of water you want to fish? Maybe a friend of a friend? Nothing wrong with asking them if you can beach your boat on their property or leave it at their dock. A nice word and a few pieces of silver will often open up possibilities.
I also might suggest you think about putting the boat somewhere on the Rideau System. Lots of access to lots of water! A lock pass isn't that expensive ($125?).
. I ended up getting a 14 footer and I took it for its first fishing mission last Sunday. I caught 3 bass and one pike. One of the bass was kind of small so never got a pic but the other two were nice...certainly had fun to bring em in (top water action is sooooo cool)
