Can I launch a runabout boat to fish inside Pillar Point Harbor?

I have launched kayaks from HMB both trailered and via cart from the boat launch area many times.  Typically if you pull up to the left side of the launch (south side) that 3rd launch ramp is shallower and much less likely to be used by traditional boat on trailers.  Thus it isn't a problem to park, unload, and set up before walking down the ramp to launch.  I usually do all my prep, park the car/truck leaving the yak at the launch, and reverse on return without issue.  If you have a trailered yak and you launch it by hand/cart at the boat launch you can ask for a trailer pass at the harbor master office.  With it, you can then avoid the launch fee and/or ticket you might receive if you have an empty trailer in the parking lot...  HMB Kayak has become my go to though and they are cool about you using their hose and washdown area.  Same rules apply though if you have a trailer.  Empty trailer in parking lot without a launch fee receipt or the above mentioned trailer pass, and you may find yourself with a parking ticket.

I completed my kayak's first "sea trial" over the weekend at Half Moon Bay harbor.  Roamed around inside the harbor.  A lot of learning from the trip; a very successful test.

Was hoping to catch halibuts, but only caught rockfish and released.

I saw some gigantic mussels; took a few home.  Are mussels from the inner rockwall eatable?  I figure if not eatable I'd use them as bait.
