Leaving Boat In Slip

[MaliWop]

To the OP. What are the details of the lake you are on? Is it a dirty lake? Lots of scum? Clean and clear? Our lake is pretty clean. We pulled our boat out once in the middle of the year last year. As soon as we pulled it out I wiped it down. This got all of the scum off the hull while it was still wet. It never looked like it was ever left in the water. Took it home and put another coat of Collonite on it, than put it back in the water for the rest of the season. There would've been more to it if our lake wasn't as clean as it is. But that's why I ask how clean the water is on your lake. The best advice I was ever given was to wipe the hull down as soon as you pull the boat out of the water. I also give the boat I wipe down at the end of the day before putting the cover on. I wouldn't be too worried about leaving your boat in the water for the season. Make sure you keep it covered when not in use (it will keep the sun off the interior and minimize the amount of sun on your gelcoat). Wipe down the boat with a damp microfiber cloth after each use or at the end of the day. If you're like me you can go one step further and wipe down with a spray on wax (I use Eagle One Wax as you Dry) at the end of each day of use. But most importantly, make sure you have a good coat of wax or sealant before dropping the boat in at the start of the season. There are a million threads here about waxes and sealants which can help you chose the right product for you. I use Collonite myself. Works great, makes the wipe downs super easy, and lasts a long time. Not to mention it's cheap (Amazon).

I totally agree with MaliWop. It totally depends on your lake. We have some of the best drinking water in the world and our boat sits on it for months at a time with zero problems. But let's say I was down south in some "hot chocolate" by no means would I leave my boat not on a lift. 

Just make sure you give it a gold scrub afterwards and some hull cleaner.

Our home dock..... 19 boats, 4 of which are Malibus, 2 Mastercrafts & an assortment of others. No blisters.

There is one boat I know of that has blisters. It's an MC & is kept in a canal nearby, no water movement at all.

Like others have said, I pull mine every few weeks, clean it, gas it up, drop it back in. Also, I pull the boat any time I'm leaving town or there is any sign of bad weather. Going on 8 yrs with this boat. Zero problems.
