My grandparents on both sides own boats.
Dads side has two lake cottages(next door to each other) in Lawton, Michigan - about 20 miles S/W of Kalamazoo.
Up there they have:
2001 Rinker Captive 21 footer I believe. MerCruiser V6 - Just your standard tubing/basic skiing/basic wakeboarding funboat.
1993 Polaris SL750 - 750cc 3 Cyl wave runner. Thing is old and slow but so much god damn fun. Blew a piston in late 2010 and sat all last summer
I want to buy it and fix it but my grandma won't sell it to me for some reason.
A Pontoon boat older than me with a 10 horse on it.
My other grandparents have a 1988 36' Carver Cabin Cruiser that he bought new back then. Twin 454's under the deck. He uses it for pleasure (obviously) and down-rigger fishing.
At their house in Florida, he has a sexy ass 2008 ProLine 29' center counsle walkaround fishing boat with twin Supercharged Merc. 250 outboards.
I personally, own none
But I hope to own that damn waverunner soon
