Wind and waves are one concern...ferry prices are another...lingcod is closed, crabbing is currently closed...yet another factor might be the dearth of suitable launches at a given tide...I live on Orcas and frequently launch at Bartwood, but it's a tricky spot for larger boats...don't know about the other islands. If you have the money, look into renting a more suitable deep-V boat from one of the local outfits. Check around at http://www.sanjuanweb.com/ or http://www.orcasboats.com/

...as if we need any more tourists in July! lol
