The Leapard 4000 should be fine. You can bring the boat between the hulls as I mentioned.
The davit system on the newer Leapards is also the best I have ever used. No need to ever tow the dinghy. It's quick and easy to hoist. A added side benefit of the davits is if you dive. Roll out of your gear in the water and clip it to the davits. Climb aboard and hit the up button and it brings your gear right to the cockpit.
