Tender to Megayachts?
How about an electric convertible? Cars got it decades ago, but in the boating world few are built with tops that can open and close with just one hand, or better electric. To be able to get in and out, it is not a typical cars system you can use. But as here, divided in two sections you can have all the practicability and safety needed on a boat.
And in an emergency, you can always get out through the foredeck hatch.
So, who will be the first to build a boat as elegant as a car convertible?
