My normal cruising amp draw is 40amps, which gives about 4kts in calm. With seas and wind, figure 3. So I would have made the trip to the south bay and back at about 1.5 knots, butt-first..

On the way back in (dang, no whales) the boat lurched on a swell and I stumbled into my pedestal - where the toggle controlling fwd/rev sits. You guessed it - from fwd to rev in an instant. Suddenly my amp draw was way down..hmmmm.

Move the plate, tighten the bolts, presto, belt is tensioned. To get at this though I have to crawl into a hole, lay sideways and sorta upside down. And I'm outside the Gate single-handing.

Voltage under 20amp load reading 50.3 at start and 48.4 at end. About 50% usable wind and had the tide with me in both direction (4.7kt ebb, 4.2 flood). Took about 8 hours (when the wind was up I had close to 8kts SOG)
