I don't think many here are very familiar with TakaCat catamaran dinks. They sure seem interesting from what I've seen on videos. Light and fast and stable.
I worry about how awkward removing the outboard in the water and transferring it to your Hat, between the odd TakaCat transom and the inflated floor and tubes getting whacked by the outboard prop. If you try it, please let us know how it goes...could be really nice. I have a Hydraulic TNT swim platform on the back of mine and currently have a heavy and too long Zodiac Hurricane 420 that sticks out 12 inches--nerve-wracking when docking or locking through.
