Longbob-

Give Maxweld a call and talk to Andy about his smaller cats. I have seen them down to 24', with a single outboard. He will build to your specs. A 24-26' Maxcat will be light, tough, fuel efficient, stable, fast, and have a great ride. Probably 18" draft at rest with the motor down. As long as you're not running rapids it will beat any similar monohull hands down.
