Hyannis Yacht Club Docks Repaired

Publish date:

SF Marina rebuilt the T-head attenuator and dock walkway array at the Hyannis Yacht Club on Cape Cod, Mass., after a series of storms.

Having completed a breakwater replacement, SF Marina finalized phase two of the project, during which Hyannis Yacht Club replaced its 216-foot dock. SF Marina used floating concrete dock segments with HD guides to accommodate new steel piles. Stainless steel tracks were incorporated to accommodate the timber fingers for 36 slips.

“Due to heavy icing in the area, we used to store our attenuator in a lagoon all winter,” Randall Wallin, Hyannis Yacht Club vice commodore, said in a statement. “Now we just leave it out year-round. The new breakwater performed better than expectations.”

The 135-by-9.8-foot breakwater was built using three of SF Marina’s SF300 floating concrete pontoons held in place with nine steel piles with center guides that distribute and absorb stress loads.
