General information
There is a large variety of motoryachts. Varying from ‘small’ motoryachts produced in series to the so called MegaYachts from 35 to 80+ meters. The Netherlands is internationally recognized in the area of (Mega) Yacht building. MARIN has a large track record in the development and optimisation of Motor Yachts. The building of large luxurious motor yachts is very similar to the building of commercial ships, but with more emphasis on the finish, onboard comfort, detials and wishes of their owner.

Services & Activities
MARIN is involved in the development of the hull design, the power optimisation and the cavitation, noise erosion observation. Special interest is payed to items like transit fuel actieradius, top speed, noise and vibrations and the alignment of appendages.
Comfort is an important issue on board motor yachts. The behaviour of the yacht in waves and when the yacht is at anchor determines to a large extent the comfort level of crew and owner. The seakeeping performance, the motions and the loads, can be analysed. This normally includes anti roll systems (i.e. fin stabilisers, bilge keels, anti roll tanks) .
Since Motoryachts always have to sail into the harbour on their own power in often relatively small harbours the manoeuvring aspects of a motor yacht are important. MARIN verifies the stringent demand on the manoeuvrability of your vessel.
The Trials & Monitoring Department is involved in full-scale measurements of ship performances, cavitation observation, pulse and loads measurements.

Facilities & Tools
Motor yachts are tested in the following MARIN facilities:
Motor yachts are tested in the following MARIN facilities:
- Deep Water Towing Tank: resistance and propulsion tests
- Seakeeping & Manoeuvring Basin: seakeeping and manoeuvring tests
- Depressurised towing tank: cavitation and vibration tests
- High-speed Basin: tests at high froude numbers (ahead and astern wave conditions possible)
Motor yacht behaviour is simulated with the following tools:
RAPID: Calculation of wave resistance and potential flow
PARNASSOS: Calculation of the viscous flow around ships hulls
DESP: Prediction of propulsive performance
SHIPMO: Motions and seakeeping of ships
WASCO: Workability analysis of ships and constructions offshore
GULLIVER, a ship designers’ edge
FREDYN: Seakeeping and Manoeuvring behaviour of ships in wind and waves
SURSIM: Calculation of ship manoeuvres
SHIPMA: Simulation of ships in ports or fairways (pdf)
