The 2nd hand marine store in Freemont (Seattle) is "Second Wave" not Second Wind.
Second Wave-New & Used Marine Supplies it's fun to browse but as with anything used, buyer beware. I have had some luck at the semi-annual swap meet that takes place usually in April and September in the parking lot of Fisheries Supply in the Northlake nbhd of seattle. 48 deg no. will announce about a month in advance. If you go, go early for the good stuff. E-bay has also served me well for sailing gear both as a buyer and seller.
happy hunting
