An anchor buried in the mud and the ground plate on your boat may make a
great electricity source. Run an insulated wire from the anchor and one from
the ground plate to a simple dc-dc converter and you can charge your
batteries:

Works for Neal.

That would be a trolling battery!

I suppose if one chose the right material for the ground plate, one could
electroplate it with the zinc that formerly coated the anchor?
Scout

Now that's a positive statement.

Read on about the dc to dc converter in the Kongsberg Simrad references

I especially like the 'simple DC to DC converter bit. What is the EMF
you are generating and what is the bandgap for a silicon transistor?

Also you can multiply voltage using a varactor charge pump that works well
below semiconductor bandgap levels. You could also use a mechanical
vibrator-relay.
