The TT Marshals' Association will try and recruit new volunteers onboard the Manannan next week.
Marshals will travel on a number of sailings to try and encourage more people to sign up to help.
More volunteers are needed to help provide cover for the Festival of Motorcycling which takes place later this month.
The recruitment drive is aimed at those people who are arriving early for the racing.
New marshals do not need to have experience as they will be paired up with those who have marshaled before.
