Stephen, I just added davits to my 430 and couldn't be happier. We went "south" for the long weekend, and for the first time, launching and retrieving the dingy was a breeze. No having to muscle the motor onto a bracket etc. The ones I have were designed and built by Ocean Marine in Canada. Mike is a great guy to work with, and couldn't have been more cooperative and helpful. Depending on the size of your dingy (mine is eight feet), and because of the fairly extreme beam of the 430, we had to do some "engineering" (had to add a bar) to make it work, but I couldn't be happier. They've made several for the 430, so this is nothing new for them. Quality is excellent. If you need more, E-mail me at SAILBURG@AOL.COMPete
