TrawlerFest-Pacific Northwest has just added a seminar about refitting vessels with solar panels and lithium batteries, while using existing generators and alternators.

Presenters Matthew Mortensen and Chris Brignoli of Revision Marine are certified ABYC marine electricians. Together they have over 40 years of experience in the industry. Both are avid cruisers, logging a combined 150,000 sea miles under various keels. This year’s presentation will concentrate on making all around improvements to efficiency aboard boats, from power consumers to power generation. 

Mortensen and Brignoli will explain their hybrid energy systems and how they can apply to any cruising vessel with the overall goals of burning less fuel and delivering a better boating experience. 

Attendees will be invited on a proof-of-concept tour aboard the 97-foot expedition yacht New Pacific (above). Thanks to the installation of a Revision HES-70, New Pacific now consumes approximately 3,500 fewer gallons of diesel fuel in a regular cruising season.   


The solar-battery seminar has a perfect complement in another technology course, "Watermaker: Buy It, Build It, Use It" with Mike Beemer.

You can buy one or build one.

When Joshua Slocum sailed Spray around the world, one thing he really missed was a fresh water bath. Many modern vessel's are equipped with water-makers, and there are many great options available. This course will take you through the theory of water-making, options that are available, why they are so expensive, and maintenance of these systems. Beemer will also discuss options and resources for the DIY boat owner wanting to save some money by building their own system.

Beemer is department chair for the Marine Maintenance Technology school at Skagit Valley College in Anacortes.  


You can both seminars and most of the others (the diesel course is one exception) for fixed prices with a four- or six-day VIP Pass, which gives you access to any seminar. The cost is $399 for a four-day VIP pass and $499 for the six-day pass. Visit our ticketing site and do some math. You'll see how being a VIP maximizes your seminar buying power.
