The Martha's Vineyard Fishermen’s Preservation Trust got a provisional go-ahead to build out new infrastructure at the Menemsha commercial dock this week.

The Chilmark select board gave the trust the green light Tuesday to construct a davit crane on the bulkhead.

Select board member Jim Malkin said its purpose is “to lift heavy items off of boats and swing them onto the dock,” and it will be constructed by John Keene Excavation. Plans will come before the conservation commission next week for final approval.

The board also approved a beach committee proposal to replace wood on the Menemsha beach seawall, using $2,245 from their maintenance budget, also subject to conservation commission approval.

Meanwhile, the board announced the completion of the bonding process on a $3 million loan for the town’s new fire and EMS building. Town treasurer Dawn Barnes noted that the town will still have to borrow another $1.4 million for the project.
