I have one of these Dinghy Slings for my boat and it has worked out great and held up for me for over 3 years now. It looks like a large floating cargo net that you float your dinghy over and then pivot up and into the transom. What I like the most is that I did not want to attach hardware
to my swim platform or dinghy. Price
but the quality was not. I considered trying to make one of these myself too but it looks like it would take a lot of time trying to find all the hardware
and sewing it together. I just decided to try it and was happy with it after I learned how to use it. I figure if it did not work out it was not too much money
and I could use it for other things.
