The day is focused on simplified stability for motor vessels and RIBs not requiring a Stability Book.
This event is a must for MCA coding examiners who want to brush up their skills in this area, as well as general surveyors and students wanting to know more about how to perform heel tests and accurately record the data. After a little theory at Haslar Marina, it is very much a practical day and a chance to get up close to understand how the test is conducted. Fraser Noble, Chairman of the IIMS Certifying Authority will lead the training with assistance from other suitably qualified surveyors. All are welcome to attend.
Life jackets are mandatory (IIMS has some available to borrow).
The cost is £130 and includes a sandwich lunch and a drink at the nearby Creek Restaurant at Haslar Marina.
