trimaran motor yacht


Norpol Yachting is proud to announce the birth of a trawler-type motor trimaran.

The LEEN 56 motor trimaran combines all the advantages of the live-aboard trawler motor yacht, dynamic appearance, outstanding seaworthiness, and optimized interior volume. This trimaran exudes balance and serenity.

This eco-friendly design is estimated to be a lot more fuel-efficient than typical monohull trawler yachts and power catamarans. This trimaran only requires a reasonable sized engine and is very fuel-efficient. Manoeuvring in port is greatly enhanced thanks to the electric motors in the side hulls.

  • Long-range cruising speed 12 knots
  • short-range cruising speed 18 knots
  • full speed 25 knots


The LEEN 56 is designed both for long-distance (transatlantic range) and coastal cruising. She is both luxurious and seaworthy. The dimensions of her flybridge are breathtaking.

The main deck features a large kitchen and dining area to port and the owner’s cabin to starboard. A few steps up, the wheelhouse and navigation area to starboard and a cosy lounge to port in which to relax and enjoy the view. The standard layout includes 3 double cabins with bathrooms.

The owner’s cabin occupies the trimaran’s entire starboard side. The bed and office area on the main deck level offers majestic views over the sea. The bathroom with a shower and separate toilet can be reached a few steps down to the hull’s lower level. The owner’s suite occupies the entire starboard hull.

The two other double cabins are fitted in the central and port-side hulls.

We can fit the LEEN 56 with additional single-bed cabins and separate shower rooms. In the 6-cabin layout, the LEEN 56 accommodates up to 10 guests. The quality furniture is designed in light-coloured wood and made by qualified cabinetmakers. The layout and fixtures of the outdoor areas (cockpit and flybridge) are left to the owner’s desires.
