We have 2 seadoos, an old 1970s tri-hull powerboat, and a kayak at the lake. I have yet to try out the newer 'high-powered' seadoo we got last year, but imagining anything faster than our first one kinda scares me.
I have a 19' Cape Dory Alberg Typhoon, two kayaks that I built, and one kayak that I bought. I love all of them. The Cape Dory is pretty quick, can take shallow water, is stable as a rock and handles like a dream. By towing one of the kayaks, I can get pretty close to some shallow areas like mangrove swamps, then kayak in to get a closer look at what little has been saved from human encroachment. One day I would like to travel in a larger catamaran or trimaran around the world.
There actually was a point where I did have the ideal number of boats back when I had a sunfish, a 21' Wellcraft (that thing could get up to around 60 mph, but burned so much gas), and another homemade kayak. This other kayak was wood framed with canvas stretched over it. Over time, it just disintegrated. The Wellcraft really belonged to my uncle who gave it to us when he was starting a business and had no time to care for it. We had that for a few years. The Sunfish I eventually sold.
we had a 21 foot searay 3 years ago but we sold it. all us kids were grown up and didnt want to go anymore. This was before i was worried about gas but it used high octane and was at leat 100 bucks a fill up and we did that 2-3 times a week
