Beam Reach

I’ve always wondered how people in Medieval times sailed. I was told by the captain that it was much more difficult because they did not have motors and modern technologies such as GPS and weather forecasts.  Sailors had to rely mostly on experience and observation. I find it really amazing. And I feel fortunate that we have the resources to sail safely through the oceans.

What makes the Gato Verde green? First of all, Gato Verde is the first Catamaran in the Pacific Northwest to make use of biodiesel. Gato Verde also uses LED lights on the boat, which are more energy efficient. The Gato uses lead-acid batteries, which are recyclable. These batteries only allow the Gato to go full-throttle for about 30 minutes (to be prudent). There are other types of batteries, namely nickel-metal and lithium. Lithium batteries are lighter and has twice the power of lead-acid batteries. To make the Gato more green, captain Todd has been considering adding solar panels to the boat.

On the boat, we make use of our resources sustainably. One good example is using sea water to wash dishes. It really worked for me as I usually prefer to rinse the dishes until they are spotless. I could do so without worry with sea water because we never have to worry about running out of sea water. The dishes are given a brief freshwater rinse after being thoroughly washed with sea water.

We learnt during a discussion the difference between “black water” and “grey water”. Grey water is waste water from washing. Usually, grey water from a boat is released directly into the open sea. It is worrisome to think about the potential harmful effects of surfactants on marine life. In the United States, boats are required to “pump out” their sewage at designated pump out stations. In Canada, however, boats can release their raw sewage into the open sea. This is worrisome. If sewage gets into freshwater sources, there is concern about contamination of drinking water. This is not a concern with sea water as we don’t drink sea water. However, by releasing sewage into the sea, we are releasing hormones, drug metabolites, and terrestrial pathogens into the marine environment. That can be harmful to marine life. Usually, raw sewage can be treated to remove harmful materials before being released into water.

In not so long a time we have learnt that ropes should not be called “ropes” but “lines” and “sheets” on the boat. Ropes the keep the sails in place are called “sheets”. Typically, a sailboat has a jib and mainsail. The jib is smaller than the mainsail, and its orientation is changed during tacking. Tacking is a sailing strategy where a boat sails zig-zag close reach, about 45 degrees to the direction of wind. Beam Reach is where a boat sails across the wind, approximately 90 degrees to the direction of wind. It is also good to remember the parts of the boat, especially when deploying the dock lines and fenders. The front of the boat is called “bow” and the back “stern”. On the boat, the direction to the front of the boat is “fore” and the back “aft”. With this special language, the boat seems to be a world of its own.
