To trailer or not?
If you bought a boat with a swing keel would you keep it on a trailer and only launch it when you wanted to go sailing? If this is the plan, I would recommend against it. It is a hassle. It is so nice to just hop in the boat and go out on a moments notice. If you are going to keep it in the water it really doesn''t matter which type you get, unless you are going to be dealing with shallow water. I bought a Colgate 26 recently (the boat you will be training on). It has a keel, but is easily trailered (2600#). It is nice to be able to trailer a boat for winter storage, or if you want to take it to go cruising somewhere. The cabin on the Colgates is kind of small for cruising but you can''t beat the cockpit size (about 13'' long) for daysailing. You could probably get a used Colgate thru Offshore Sailing School for under $20k.
