Re: leaving boat in the water for awhile
That's probably about it and it will ruin that nice paint job that Triton puts on their Alum's.
Other option is to buy a hoist and hoist her up.
Some folks that have lake property have a driveway that goes into the water and others just have a rail system.
In the case of the driveway, they leave the boat on the trailer and just back the trailer into the water (leaving it while boating) and pull it back out when finished....some have a shed/carport thing and pull it up and under that; works great.
Same thing with the rail. Have a dolly that holds the boat and use an electric motor/winch system to launch and retrieve.
