I just bought the 390DA and looking for some advise from anyone with the same boat. It has an integrated swim platform and I am looking to put an AB Mares 10 VSX (10.6 length and 5.7 Bean weighing 400LBS to 450LBS depending on motor) or similar dink on the transom as well as be able to put a Sea Doo Spark that weights 438LBS. I have been looking at the Hurley H30+ electric mentioned in other threads here. Here are the questions. 1. Will it fit with room to get on board? 2. With the Transom rear wall is there room to swing it down into position? 3. Is the height of the swim platform to the water going to be an issue? 4. Will is cause any issues with the handling of the boat and getting her to plain? Thanks for any advice you can share.
