Discovery Marine Surveys


Al's Hat,  Cpt. A. P. Routhier 1968  Hatteras 41 classic motor yacht.

Free presentation.

In the fall and winter months I offer to visit the clubs and marinas of the area and do small marine related presentations and 'tech.-talk' that are informative and entertaining.

These presentations are free.

The presentations are usually about one hour long, the format is informal and relaxed.

This fall and winter, the topic is:


Stray current and galvanic corrosion are 'hot' topics on the docks these days. Why you should walk away from someone talking about 'electrolysis'.

The long title could be: ''Fundamentals of AC, DC, GC, bonding and grounding of marine electrical systems, their relations to ESD, galvanic corrosion and suggestions on upgrades and protection methods.''

This presentation is an overview of marine electrical, how they are/should be built, how they fail, what happens when they fail, and how you can protect your boat.
