The LARC continues to survey despite a 15-20 mph sea breeze.  They are on the other side of the inlet, and have surveyed a lot.  Waves on the ebb tide shoal are directionally beserk. Colliding crests with 90 degs (and more) spread.  Small crests, but they combine to make 3′ local peaks. 3-5 sec peak period.  Steep, savage little bastards that buck small craft around.

I talked to the LARC driver (he came ashore 75 m upcoast from our house).  He says they
* cut a shallow new channel all the way out.
* have 3-4 more hrs  work tomorrow  to complete the survey
