What a great sail today. We had wind 15-20knots from the east all day. I put up the cruising chute, but then pulled it down later as one of the repairs from our disaster in Ibiza last year started coming undone. More repair tape and up she went again.
The kids woke up and had toast for breakfast and a sea sickness tablet, only to have all but Louisa throwing up. As soon as they were sick they felt better and they had a morning of lounging around reading books while Helen and Rob took it in turn to snooze.
Late morning Rob attempted to rig the towing generator (the wind generator with a long stiff rope and a propeller on the end). But after 10 seconds it pulled the shaft of the generator through and rammed the windings into the end of the casing. So I run the adapted funnel down the rope so that it blanked out the propeller and hauled the rope in. (If you try to pull the rope in with a spinning propeller on the end the rope tends to twist uncontrollably, with your fingers or hand or something being twisted with it - not nice)
I then spent all afternoon dismantling the generator, discovering the problem (the internal circlip groove was worn or inefficient), and then fixing it by drilling a hole through the shaft behind the bearings and putting a washer on and a split pin through to stop the shaft slipping through the bearing. At sunset I let the prop and rope back out and the thing worked ok. It squeaked like hell, lost us about 1/2 a knot in boat speed and only made us about 1-2 amps - So I was not that happy.
Then during the night I decided to pull the rope in. I attached the funnel and lowered the string drogue into the water (to pull the funnel to the prop). But the string found the end on the spinning generator and like something out of a cartoon, where the goofy gets his tie caught in something spinning, the string winds itself up, pulling the funnel up to the generator. Now the spin has a lot of torque, there was no way I can stop the spin, so the funnel is now spinning around the end of the generator, whacking on the solar panels 2 times a second. So I quickly grab another funnel and cut it and tie it up with another drogue. Now I try to encircle the rope with the new funnel while trying to reach behind the now dangerously spinning old funnel. I manage to tie it around the spinning rope after about 15 minutes, and let the drogue into the water. It slides 10 feet down the rope the string now manages to get caught in the rope and the same thing happens - it winds it self up and starts waggling violently behind the boat in the dark. The whole episode was difficult and potentially nasty, but I still have the problem of getting the rope pulled in.
My mind was weighing up the benefit of another 50 amps a day, over lost speed, excessive load and wear on the generator, dangerous handling and the now pressing need to stop the whirling funnels before they did any damage. There were 2 safe ways of stopping the spinning: Stop the boat by taking down the cruising chute, or cut the rope and loose the prop. I cut the rope. At least I wont be tempted to use the generator now - It was ridiculously dangerous.
Helen managed French and Science lessons for Sophie and Emma in the afternoon, while Jack and Louisa played downstairs.
