Murre Specs & Equipment

Murre in Sea of Cortez

Murre in Mexico, 2010.

(February, 2016. This page was created some time ago as an advertisement for Murre, who went on the market in 2015 and has subsequently sold. I’ve left the page up as it contains a good overview of the Mariner 31 specifications, projects completed on Murre between 2003 and 2010, and Murre’s equipment list for the 2010 – 2012 Pacific cruise.)

I bought Murre in 2001 and spent many summer weekends, and even some work nights, sailing her to the far corners of the San Francisco Bay. For years, the favorite activity of my wife and I was to high-tail it to Murre on a Friday evening and be anchored at Paradise Cove or China Camp before nightfall. In the winters I often put Murre in a covered berth where I slowly rebuilt and readied her for more challenging waters outside the Golden Gate.

In 2010 Murre and I took off. Over two years we made three long ocean passages; we explored Mexico’s Sea of Cortez, the tropical paradises of French Polynesia and Hawaii and even Alaska’s glaciers and the Inside Passage (map). Our course covered thousands of miles of open water; we passed through the trades three times and over the equator twice; survived calms and gales; saw seabirds and dolphins and flying fishes and the vast Pacific from 20 south latitude to nearly 60 degrees north. Without doubt it was the grandest adventure I could have imagined.

We returned under the Golden Gate late in 2012, and I’ve since been organizing a different adventure requiring a much different boat.
