Re: New Used Boat Advice - Lots of Small Children
I don't think you'll be happy slalom skiing behind a deck or toon, or 12 person boat of any kind--you may have to sacrifice some of your criteria. I also don't think the other 11 people are going to have much fun watching you ski, and if you give them each a turn, you're up next 3 hours later. and teaching someone to ski behind one often results in axe murders.
If you must get one boat for 12, look into the big Carolina Skiffs, too. They have high sides, good floatation, aren't expensive, run well and hold lots of people.
Remember that a boat for 12 will be expensive to operate, store, and to repower when the time comes.
Keep in mind that a boat rated for X is comfortable for X-3. When it's hot, you don't want to be all stuck together. Children like to move around; guys like to stand. When it's colder, one side of the boat is catching some spray but you can't shift half your passengers to the dry side if you're full to capacity. And 12 people tote a lot of stuff.
This may sound extravagant, but why not consider 2 boats? A cheap old basic skiff for skiing at $3000 and a barge (toon, smaller deck, etc.) at $7,000? The families can hang out, anchor, toodle around while you and two others ski and tube in the vicinity. Someone can go out fishing in the small craft while the rest nap or hang on the beach.
My point is: $10 K, families, 12 bodies, slalom skiing, tubing--a lot of requirements for one vessel. Those children will be bigger before you know it--and will want to bring friends. Some trips (hopefully!) you won't have the whole clan and will be glad to have a smaller option. And more economical.
I've done a lot of large crowd/small boat vacations--whole weeks on an island--and having the options presented by several small boats is great. PLus since you have to buy an older cheaper boat, you it won't be running all the time--you have a spare.
