i think you can still launch at coyote point just before the sfo airport off highway 101, and pete's harbor in redwood city off the 101 at the woodside road exit east.
give slammin sam a p/m.
he works right there in redwood city and would know whats up.
as for ocean waves, i launched at princeton harbor north of half moon bay on highway 1, but that was over 6 years ago.
these a smooth harbor (5mph ???) to the breakwater exit, then "BIG" waves are waiting for you there.
they still might have the jetski only area posted, but remember thats a big ocean out there.
what they dont know wont hurt them, unless you break down, or get stuck in the breakwater.
good luck
