I don't quite get why anyone would pay for a slip and then still haul the boat out every day. That defeats the purpose.
We used to trailer the boat, launch it, pull it out, etc (all the things you mentioned) and it was a PITA. You see all the weekend yahoos at the boat ramps each weekend? Guys who have never backed down a trailer, guys who run into the dock, boats die at the dock, jet ski fools all around. That was enough to get on the list and get a slip. Well worth it even though the gas (same Chevron gas you buy at the station) is a bit more pricey but if you're going to owna boat you can't go cheap on everything.
I don't get why people wouldn't use a slip they paid for either. Dumb, IMHO.
Those weekend yahoos are so annoying! But we had it down and were in/out in a matter of minutes. I liked checking out the boat everyday and keeping it clean. I also liked knowing that nobody was going to be messing with my boat when I wasn't there, too. But, to each their own.
