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.  Scroll down for all the forms, fees and payment options.

YDSA has always stood for the highest standards and therefore the attainment of membership is seen as ‘The Gold Standard’.


The YDSA Academy was launched in 2019 and will be adding new modules and practical opportunities as the programme develops.  All members have login details and a personal record of modules completed.
