I'm on a water budget (on the beer to champaigne budget scale), but I like to dream, and I like to figure out what changes I might make to make my "next" boat better for my family and me. One of the things that we REALLY want in our next boat is a good swim ladder. It was a real challenge to climb aboard our 1984 Catalina 25 via the ladder. The round rungs hurt my kids' feet (and mine), and the stern rail was VERY awkward to get over/under. I'd really like a sugar-scoop transom, or even a swim platform (like the O'Day 272's), but I'm not overly picky.
One idea that struck me was to just put a small, powerboat-style swim platform on the back. Sure, with the way the transom slopes on many sailboats boats, I'd probably have to find a way of offsetting the mouting brackets, I'd want to reinforce the transom in that area, etc., but that all is "do-able". And it strikes me that a lot of people want to, and actually do, swim off their boats or use a dinghy, and both scenarios seem to benefit from such a swim platform. So, why don't I see a lot of them on sailboats? Or, put another way, why is something like the picture below (which is from a sailboat, if you couldn't tell) a bad idea?
