I was looking at the new WDFW fishing pamphlet and noticed that the two pole endorsement will apply in MA 13 year round.

"Two-Pole
- New this year, anglers can fish with two poles when
in possession of a valid Two-Pole Endorsement in Marine Area
13 year-round. Other coastal and Puget Sound salmon fishing
opportunities with two poles include: Sinclair Inlet in Marine Area
10 (July 1-September 30), the Tulalip Bubble in Marine Area 8-2
(May 30-September 21, 2014, and May 29-June 29, 2015), Willapa
Bay (August 1-January 31), and Baker Lake."

I also noticed that you may use two poles in allowable areas even without the endorsement on free fishing weekends.
