Slowest passage ever?

If there is any wind, we're a 6 knot boat. We have typically averaged about 150 miles in a 24 hour period on passages. From Trinco to the northernmost Maldives port of entry is 720 miles.

This one has been different. Aside from the south coast of Sri Lanka, where the light NE trade winds are deflected and increased by the island, and the engine was shut off for a day, this has been a motorboat ride. And because we've still got a long way to go, we're maximizing our fuel range by motoring and motorsailing slowly. At 4 knots.

At 4 knots we burn about 0.4 gallons/hr, at 5 knots it's closer to 0.6. Fuel consumption in displacement boats is a very nonlinear curve.

We carry 60 gallons of diesel. At 0.4 gph we can motor for almost 150 hours. 150 hours x. 4 knots = 600 miles. We've never tried to maximize our motoring range until this passage. Let's all raise a glass and say "cheers" for bit of wind out here. 320 miles to go as of 3 am today.

Its boring to motor for 6 days. 🍻
