Commodore Roger Cave says it's a community facility for people in the town
The commodore of Peel Sailing Club says he is 'angry' at the decision not to renew the lease on the building after 2028.
Roger Cave says it's operated from the site for 40 years and disputes claims it was built in line with the development of the marina.
Club president Harry Owens says they heard rumours of the closure last year and it was formally confirmed to them in March.
Mr Cave says the RNLI, Moddey Dhoo Motorcycle Club and other local organisations are members of the club and use the facilities.
The commissioners have previously said they need to take the building back to do maintenance work including electrical, plumbing and the roof.
