We have the wrong boat!

5 years ago we found a great deal on a Catalina 250 WK. We kept it on a local Texas lake and sailed it year round. Then we got a lake house (Cedar Creek Lake) with a boat lift. Now we have the boat in our backyard and can walk out and go sailing. Except, the depth at the lift is 6 feet. We draw 4 feet. And the last few years we have had flash droughts that suck the water out of the lake. As a result, over the previous 4 years we can sail only 6 months a year. Since we live on the lake we do not spend overnights on the boat. So I need a boat that draws 2 feet instead of 4. I am thinking of a Capri 18 or 22. We will be limited to 4 people but we rarely take more than 4 out anyway. We do sail year round so need a "dry" boat. Speed isn't super important, but a lighter, easy-to-handle and dock boat would be great. What do yall think? Any recommendation for big- small boats?
