Having tour boat slipped is very convienent, however it allows all the nasty growth to attach to your hull. Antifouling paint helps but it just adds more maintence. In my younger days I moored my boat but the constant cleaning drove me nuts ( yes I am anal about keeping my boat clean). I ended up getting a lift to lift the boat out of the water. This is the way to go!!! However not many marinas allow this nowadays. I was fortunate enough to be able to rent space from a cottage owner and we ended up building 4 lifts for all of our boats. When the opportunity for the lift became lost my boat went back on the trailer and has been there since. My trailer is set up for easy on and off, I can load and unload by myself and dont need a dock, I am 73 yrs old. Only you can make this decision and it wont be easy, lots of things to consider!!!
