Trawler 52


Trawler 52

The design meets category ‘A’ of the R.C.D. Seaworthy and long legged with a range of over 2000nm.

The Trawler 52 is different from the typical ‘Passagemaker’ is the low enough air draft for the continental waterways. Most comparable seagoing designs simply cannot navigate large parts of these waterways.

Tough rugged steel construction (over Lloyds ‘A’ S.S.C) and heavy displacement(30 tonnes) provides comfort and reassurance whilst cruising.

A passive ’Flopper Stopper’ rig can be incorporated to further reduce roll and improve sea keeping.


The design benefits from a rounded multi chine hull form along with a low superstructure, naturally leading to a gentle response to beam seas.
Many remote and beautiful harbors are drying ones, yet the optional bilge keels allow the 52 to take the ground safely.

Accommodation while underway is important for a ‘passage maker’. It is generally agreed the most comfortable area onboard is the last third of the length of a vessel. The owners stateroom, saloon galley and most importantly the helm station are located in this position.
