The BB37 is constructed using GRP sandwich lightweight construction with an extra reinforced keel sole, double glazing, five hatches, and four sliding doors.

Comparison with Kronland 2

Both motor catamarans share a generous amount of space, comfort similar to home, easy and safe handling, a very shallow draft due to lightweight construction, economical operation, and long range.

The difference between Kronland 2 and the BB37 is that Kronland 2 offers comfort and functionality for travel inland and along sheltered coasts. It can navigate narrow and flat areas where others cannot. The BB37, on the other hand, is designed for sea travel, allowing you to reach islands and unfamiliar shores.

Experience the beauty of nature from the king/queen size bed, listen to the sounds of nature, enjoy your freedom, and wake up to the rising sun. The BB37 can effortlessly reach European capitals via inland waterways.
