Dan,
This sounds like a troll but I'm going to bite anyway. Your response below
has got me curious as to how much cold water diving experience you have, and
I don't mean this as an insult.
A little background on why: I learned to dive in Florida while stationed
At Homestead AFB. Eventually I moved back home to the Northwest and a buddy
invited me diving on his dads boat in the San Juan Islands. Talk about
culture shock, this macho diver from Florida (me) was in for a rude
awakening with this cold water crap. Comparing diving in these two areas is
like comparing apples to oranges.
From about April through October visibility in the 3-5 ft. range is the
rule up here, not the exception. Its also known as the diving season
here.Big currents are also the rule, not the exception. Winter is a much
different story, but you can't get many people in the water when the air
temp. is 30-40 degrees F.
The seas here are also nastier, A 3-5 ft. sea up here is twice as nasty
as I remember it being in Florida. I don't know how to explain this one
except that while Florida currents usually run one direction we get two
currents trying to run against each other.
I'd like to offer food for thought on the drifting deco debate also.
Recently we were diving on a reef (70' deep)in the Straits of Juan De
Fuca. This reef is so small ( about 100ft. x 25ft.) you have to Use a GPS
and depth finder to find it, but its loaded with fish. You get close with
the GPS and then watch for the blip on your depth finder. With a 2+ knot
current running we marked the site with a standard 24" inflatable float ball
with an anchor for the dive. After the first dive we went back to port for
lunch and came back using the GPS to navigate. It wasn't until we got about
50 ft. from the ball before we could see it, we were all shocked and I was
glad I wasn't doing a drifting deco. I don't know how to explain it but the
seas are just different up here.
All things said and done I would take a dive at Dunkin Rock (our diving
Mecca) over anyplace else in the world that I've dove. You haven't been
diving till you dove " The Rock".
