My boat has a davit on the bow that
used to lift a 10' Avon. When in the slip, you can't launch the dinghy! Even if you're stern in! One of the favorite past times in our marina is going to dinner in the dinghy but we would have to untie the boat and move out of the slip to launch.
A bow mounted dinghy is very limited as to where you can launch it. Conclusion: We sold it!
P.S. The dinghy in the photo is not ours...it's a neighbor's that is hard to launch from his boat too!
