Steve:
If you are planning to do much swimming from your Nonsuch and/or using a dinghy often, I guarantee you’ll be much happier with the excellent Swim Platform that Stainless Outfitters also sells.
It has a flip-off ladder that extends deep enough to easily get you up onto the platform, but it makes a good place to stand and rinse off if you have (or add) a pushpit fresh water shower, and it provides MUCH easier dinghy entry/exit!
Here’s a link from Google that will give you lots of photos of it:
Helpfully yours,
