First thing to look for?
Availability ... which is usually the biggest issue. After that, the other conveniences are icing on the cake!You might want to try a mooring. They are normally about a quarter of the cost or less, your boat takes less beating in a blow, and your boat looks way more picturesque when you are driving by the lake!Seriously, some marinas can be very exposed to the wind, and in your midwestern location, I would bet that could be the case. If the slip isn't wide enough to tie the boat off with adequate space or adequate cushioning, you can suffer some damage at times. I've seen it on our lake even though waves aren't a problem. Often times, the slips are designed with one finger for every two boats, which does not give you much opportunity to tie yours off at four corners.On a mooring, be concerned about adequate weight (yours won't need much, especially if it is sunk in mud), and keep your pennant from chaffing. We use a bridle for our Starwind 27 with 2 pennants for redundancy. Our mooring block is close to a yard of concrete.A mooring is less convenient, what with the rowing out to the boat and all that nonsense. But the cost savings is pretty nifty. We pay $450 for our season, vs a minimum of $2,800 for a slip (if I could find one). The slips I could find are WITHOUT shore power or water. There are a few locations on the lake that offer those amenities, but they are unavailable to sailboats and besides they cost about $4,800 for the season.
