You are still not necessarily entirely a powerboater. You can use a kite w/o a
mast and run downwind or even upwind if you get the hang of it. Of course, you'll need more room than a
canal.
But on to perhaps more serious issues. I have spent time on
cabin cruisers of varying lengths; a 22-ft
Catalina, a 30-ft
Islander, a 29-ft
Ericson, and now an O'Day 37. If the weather's nice, the company's good, and you don't mind bending alot, things might be fine. But tight quarters can make strange bedfellows. Everyone needs a little private time, which is hard to find on 23 feet. Or say someone gets the flu. Nowhere to go but topsides for the healthy crew, and the boat becomes a petri dish.
Keeping your trips on the short and near-to-hme side for the first few times is a good plan. You never know if you might need a "vacation" from the vacatointo save a marriage. Have lots of good
food,
beer and/or wine on board and have a great time!
I'd also recommend some towing
insurance, just in case that trusty
motor goes kerplunk. I also agree about keeping the
fuel cans off the stern. Maybe several smaller cans?
Best, lorenzo
