Other organisations have since adopted the format or are in the process of phasing in the format on their waterways. The Boat Safety Examination is now a requirement for boat owners to renew once every 4 years. In theory it’s there to help to prevent events such as explosions, fires & pollution and unsafe boats being kept on the waterways. Whilst the Boat Safety Examination is something that boat owners have to worry about once every 4 years it is also important that owners keep their boats maintained to at least the BSS’s minimum safety requirements at all times. The Boat Safety Scheme provides plenty of online content that can be used by owners as a reference for keeping above the minimum safety requirements. BSS Examiners at Maritime Survey do not have to give guidance on issues that may arise that aren’t featured in the BSS checklist.
