Cruising

How far can you go?

Electric motors run reliably as long as they have enough power supplied to them. The question of “how good are they?” is just the incorrectly asked question “how good are the batteries?”

We have crossed the Atlantic twice and visited many ports along the way. We have managed this on just eight 100ah batteries hooked up in series and parallel to give us 200ah at 48v. As a result, we have practically no range and as a result do not count on our electric motor to take us far. We have been using it just for docking and maybe for maneuvering around an anchorage, otherwise we rely solely on the sails to get us from port to port.
After 4.5 years, we have never actually done a proper range test to see how it works. Now is the time to see what this baby battery setup can do!

Sailing the Caribbean: Season 6 is Coming

Normally, people go cruising just to sail the Caribbean; these people also sail straight to the islands in the most direct way possible and thoroughly enjoy life. We went the really long way to get to the Caribbean, arriving after 4 years of cruising and two Atlantic crossings. It’s a good thing we did the other sailing first because we might have never left the Caribbean!

How to calculate wind shadows

Hiding in the lee of an island is a great way to protect yourself from punishing winds. The land blocks the sea from building waves that will rock your yacht as well as blocks the wind m, allowing you to anchor rather peacefully in some horrible conditions!

When you are looking at a new place to go cruising and need to find happy hiding holes that you can tuck into if the wind builds, how can you figure out how far away from land you will still be protected?

Navionics will tell you the elevation of various points on a landmass. Some are in feet, some are in meters, but the math all works out the same.
The equation is simple:

Elevation in Nautical Miles x 20 = Distance of wind shadow in nautical miles

For example: 564 feet (elevation) / 6076 feet (number of feet in 1 nautical mile) = 0.09nm tall

0.09nm x 20 = 1.85nm wind shadow

In other words, if you are within 1.8nm of that point of land, you will experience much less wind as you will be shielded from it.
Another example would be 168m right next to it:

168m x 39 (number of inches in a meter) = 6552 inches / 12 (number of inches in a foot) = 546 feet / 6076 (number of feet in a nautical mile) = 0.089 x 20 = 1.79nm wind shadow


To make it easy, just do these calculations:

If the elevation is in feet:

Elevation / 6076 x 20 = Windshadow

If the elevation is in meters:

Elevation x 39 / 12 / 6076 x 20 = Windshadow
