You could always have it launched for you via travelift. Yes, it increases your costs (roughly $250-300 for the haul-out, maybe the same for the launch, maybe less because it won't get power washed). Just putting it out there, though.
We'd all like to pay less than we do, trust me!
I'd suggest looking at it from a different perspective - the money you save by putting it on a mooring will help pay for the winter storage, and also helps you afford the 27 over the 25. What's your real difference in price between the two?
