The options for getting to the Vineyard, particularly at times other than the summer high season, continue to diminish.

Following the recent cutbacks in off-season high-speed services to the Island from New Bedford by the New England Fast Ferry, two more boat lines have flagged their intention to reduce the number of runs they do to the Island.

Hy-Line Cruises has notified the Steamship Authority, which licenses ferry service to the Island, that it intends to shorten by two months its operating season between the Vineyard and Hyannis.

If given approval by the SSA governors at their monthly meeting next Tuesday, Hy-Line will run its high-speed service between the Vineyard and Hyannis by the Lady Martha for only six months, from May to October, and drop service during the months of April and November.

And Cape and Island Transport Inc., which operates the Pied Piper service between Falmouth and Edgartown, proposes to cut the number of runs it does in peak season between June 20 and Sept. 1, from 36 to 29 per week.

Pied Piper also would run three daily trips on Fridays, Saturdays and Sundays during the spring season between May 23 and June 15, but would cut its autumn schedule between Sept. 5 and Oct. 13 from three daily trips to two on Fridays Saturdays and Sundays.

SSA governors are expected to consider the Hy-Line proposal at their meeting on Tuesday, although the Pied Piper request is likely to be deferred.

The Steamship Authority meeting, which is scheduled to start at 9:30 a.m. at the Candle House on Water street in Woods Hole, promises to be otherwise largely uneventful.

Apart from the usual updates on progress with various capital projects, only two relatively minor policy changes are set for discussion. One would provide discounts for disabled passengers; the other would change the rules for wait-listing for large trucks.
