What I unabashedly call Lamoine, Maine’s first electric lobster boat, Eleccentricity, has just received a roof or “dodger” for the future installation of photovoltaic panels. The ultimate goal is to have a zero-emissions motor boat. A side benefit is shelter from the rain and sun, not to mention an elevated platform from which to spot pirate ships.
I put this robust structure together in my garage. Of course it would not fit through the door when assembled (I knew this, really), so after disassembling it and painting or varnishing all the parts I had to devise a way to lift the roof onto the supports. I had integrated a lifting tab into the roof for this purpose. Two big trees in the driveway gave me the idea that I could run a line between them and hoist the roof high enough to bring the boat under. The first attempt failed because I used nylon rope which stretched so much the roof only got about five feet off the ground. I quickly replaced the rope with cable and there was zero stretch as the roof climbed about 12 feet. Then I simply maneuvered Eleccentricity under, mindful of my sudden possible death from falling dodger. I forgot to mention my difficulty finding a thing to tie the block-and-tackle line to after hauling the top up. I settled on a hooky thing underneath the bumper of my Honda Fit. I had just used it to pull out a big ornamental plant root ball, but that’s another story.
Anyway, a little jockeying of the boat and backing up of the Fit and the top settled down nicely without me even having to climb into the boat. Since then, I reloaded the 7 batteries and the electric outboard and am nearing launch for the summer of 2012.
One of the pitfalls of designing and building one’s own boat is the knot in your stomach which reminds you of a possible huge mistake. What if the dodger makes the boat so top heavy it flops over in the first strong wind? It does look unstable on the trailer, but I wanted to achieve standing headroom, and I’m not THAT tall. The 400 lbs of batteries in the lowest part of the boat should help, and after all, sailboats are notoriously top heavy. That’s why they have lead keels, and I have a lead keel too. Another concern is the fore-to-aft balance. Last year, without a dodger I found Eleccentricity a little stern-heavy. This put the motor well too far into the water and created more drag than I had hoped for; I was trying for a transom above the waterline. The extra weight of the dodger (probably about 150 lbs–I didn’t weigh it because I broke the bathroom scale weighing the boat last year) will shift the balance more toward the bow.
Last year when I first launched I wired up the motor in reverse and the steering too. I could only go backwards by steering the wrong way. I am not afraid to look like a fool. This year’s launch may be just as entertaining.
