Equipment, software, techniques, information and more

I love my Spectra watermaker, but the filters are really expensive. Today I found a replacement activated charcoal filter. Spectra resells the KX Matrikx Industries brand for $30.50. The filters are nominal 3 micron extruded carbon, 10″ x 2.75″. Filtersfast.com has the same filter (KX Matrikx +10 /2 10-250-190-975) for $8.50.

I just concluded a passage from British Columbia to California. Between Bodega Bay, CA and the Farallon Islands we encountered dozens of large whales: humpback, grey, and many individuals of a much larger species. Here is a video I took of two of these unknown whales. Any idea what they are?

I’ve had problems with timed transmit mode on my Raymarine C70 for years. The v4.29 software update seems to have finally solved the problem. Updated documentation is here.

Dial A Buoy

NOAA has a useful service called Dial A Buoy. Unfortunately, the only phone number listed is 888-701-8992; if anyone knows of a non-800 number, please let me know.
Please, no bad puns about San Francisco and “Dial a Boy”. This is a high class blog.
