Port Townsend is one of
the more popular destinations for pleasure boaters in Washington's
inland waters. During boating season, the nearshore area off the
downtown waterfront is heavily used as an anchorage. Dur ing festivals
and events, the use can become very heavy with up to 50 vessels or
more anchored off the town waterfront. A small number of the vessels
end up anchoring in the eelgrass meadow that extends more or less
continuously from the Port Townsend boat Haven to Point Hudson. The
eelgrass beds along the downtown shoreline (from Point Hudson to
Indian Point) vary from 175 ft. in width between Union Wharf and
Point Hudson to 410 ft. between Indian Point and the Boat Haven.
The average depth at the outer edge of these eelgrass beds is -13
ft at mean lower water.
In most cases, these vessels would only have
to move offshore 50 to 100 ft. (2 to 3 boat lengths for a 30ft
vessel) to eliminate the
anchor impact. Damage to the eelgrass bed is observable as vessels
pull up anchors weighted with plants and mud. In addition, as
vessels swing on their anchors or drag them in strong winds, the
chains and
anchors can plow up plants as well.
As a side benefit, vessel
safety is enhanced. Anchors hold poorly in vegetated bottom and
are more prone to dragging. Port Townsend
experiences major windshifts at any time of the year and a
south easterly wind can quickly turn the anchorage into a lee shore.
As a result, vessels do go up on the downtown shoreline with
the potential
to cause property damage and pollution incidents. By moving
vessels
out into slightly deeper water where the anchoring is better,
these incidents should be reduced. |
