I'd appreciate hearing from those who have installed a lifting davit on their 310. I took the one from my old boat thinking it would be a routine install on my 310-no such luck-it will require some significant re-fabrication. So I am going to sell it and get one perhaps from Garhauer or Kato who appear to have experience of what's needed to fit it to our boats. Anybody have pictures of how they did it? Thanks all.
