Commentary: Electric Motors
I've got 45 days of sailing in so far this year
and it seems the summer weather is here along with the light winds. Several times winds have died to nothing and I've had to resort to turning on the engine--including today. The "engine" in these cases was a 12 Volt trolling motor attached via a fiberglass tube though the rear deck adjacent to the transom and projecting, when lowered, into the water. The exit port in the hull is above the waterline when the boat is upright. We hoist the engine up to reduce drag while sailing--a one handed operation. When I first saw these miserable looking motors, I was shocked. I thought, "What a joke!" After several years of using these motors, I've found them to be very reliable, with the principal failure point being the on/off switch--which is an easy repair. The will drive these boats [23' Ensigns] against our typical winds. Only in extreme conditions do they find difficulty motoring against the wind. The will run for more than two hours on two group 27 deep cycle batteries. They charge quickly with a low budget battery charger. Electric motors have the advantage of not running out of power, but tapering off rather than quitting completely. As lame as they look, I've come to the conclusion that electric motors are the way to go for me also. On my Etchells, I've occassionaly been becalmed and struggled against the current of the river in the extremely light winds I often encounter in the summer in the late afternoon on LIS. When I bought the boat, I was provided with a seized up Seagull outboard, and an odd looking outboard motor bracket that attaches to the port side of the boat--which means the motor must be detached whenever I want to sail. The net result is I've never used it. The Seagull outboard is still sitting in the basement--I probably should remember to toss it out. I never attached the mount, and I've been patient to sail, at times, several hours into ebb currents the short mile up the river to my boat club. My Etchells will move on a breath of wind but my crews have threatened mutiny if the horsefly's are out in these conditions! I need a better solution! My old mount would be very handy for a small lightweight trolling motor. My plan is to install just one deep cycle battery, and use that to drive a few electronics, and a light-weight trolling motor. I feel one battery will be enough to drive my sexy slim Etchells. I heartily recommend electric motors. In many days running corporate events, teaching sailing, and running small charters on these electric motor equipped boats, the hassles have been far fewer than gasoline powered outboards I've used. |
