A far better way to keep your boat shipshape — and it's free

Port of Friday Harbor Marina distributes free adapters that make pumping out boat sewage cleaner and easier

The Port of Friday Harbor Marina is partnering with Washington Sea Grant and Washington State Parks to distribute hands-free pump-out adapter kits that make the job of emptying out onboard sewage holding tanks cleaner and easier. The kits can be picked up at the Port's harbormaster’s office through the summer.

The advantage of the adapter, which screws into a boat’s waste-discharge deck fitting, is that it can be securely clamped onto the pump-out hose. This means that boaters don’t have to hold in place the rubber nozzle found on most pump-outs, which may seal poorly and leak or spray sewage.

Each free adapter is contained in a waterproof tube that also includes pump-out instructions, a pair of rubber gloves, and a QR code that links smartphone users to a map of pump-out stations.

“We’re a certified Clean Marina, with many ways for guests to pump out. Handing out the adapter kits is another step in being a green facility,” said Port of Friday Harbor Harbormaster Tami Hayes.

The adapters proved tremendously popular last summer, when Washington Sea Grant began distributing them as part of a campaign to encourage boaters to use pump-out stations.

In addition to Friday Harbor Marina, Washington Sea Grant is partnering with the Coast Guard Auxiliary and other groups and marinas to get the adapters into the hands of boaters around the state.

In addition to distributing the adapter kits, Washington Sea Grant has created a Google map showing all 150 CVA pumpout locations in Washington. The map can be accessed using the QR code on the pumpout adapter instructions or at
