The key focus of the YDSA is to support Members to provide services of the highest standards to clients in surveying and designing of commercial and pleasure craft under and over 24m (excluding ships and cargo vessels).

YDSA offers a Code of Practice and Guidance Notes, a Sample Survey Report Pack, a Code of Ethics, a standard survey contract, an insurance scheme, plus assessment and feedback on reports submitted for membership, plus a range of training events to support members’ development within a training framework for career advancement.

YDSA has always stood for the highest standards and therefore the attainment of membership is seen as ‘the gold standard’.


We provide a range of courses throughout the year to assist surveyors and designers in their professional development and offer great networking opportunities. Some of these events are for members only while others are open to non-members. For these events Members enjoy a discounted rate.

Please see the Courses & Events page for more details.
