The Bear' thoughts...
Macgregor made a 33' that was heavy duty vehicle trailerable though for going off shore Pacific Seacraft's Nor'Sea 28 would be my pick. Very capable, seaworthy craft. Several different layouts avalable. Heavy, 8000#, usually cutter rigged, inboard , narrow 8' beam, can be single handed. Usually pulled with f350 heavy duty pu. Something to think able is big boat needs lots of water under it. How deep is how much of your lake?
