This is a new kind of boat : the upper part is a pleasure boat with the helm, a bench and a wooden box which contains life jackets. The mast carries two folded sails. The under part is a submarine with a shell made of glass to enjoy the under water world. There is also a bar with bottles, glasses, and a chair. The upper part is releasable.
I built that set because I imagined a 2 in 1 boat which could permit to have a pleasure boat to sail on the sea when the sun shines AND another to admire the seabed and having refreshments.
I would like this build become a great LEGO set because it's an original boat, and the owner can personalize the seabed.
I know the product can be upgraded but if you enjoy the idea, vote for it.
