Keith , an interesting post.
Thanks for including your wind and current assistance .
I have a similar trip , but its 55nm each way.
If you get it right , with winds and currents assisting you , its a pretty easy trip.
But when they are working against you , it can seem to take forever , and use every bit of horsepower you can get out of the engine.
It would be interesting to see how you would go , working against the wind and tide .
Have you tried it at all ?.

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)
