Partial surveys are of a reduced scope compared with full condition surveys and insurance surveys.
Partial surveys are tailored to your specific requirements. For example the assessment of osmosis in the hull or the integrity of a steel hull including thickness measurement without removing protective coatings.
It can also encompass an inspection of your own yacht or boat to prevent breakdowns during the season, which are often avoidable.
This kind of inspection cannot be carried out in an optimum way by a yard.

It can last half an hour or much longer.
Sea trials are conducted to measure a yacht’s performance and manoeuverability and general seagoing capabilities.
The propulsion, engine(s), steering characteristics and thrusters are part of this type of survey.
