Oh, joy!

We got the news we'd be going back in the water Saturday. She went afloat no problem, and Joseph Griffiths had the wheel again for his knowledge of the narrow channel: "Don't look at your depth sounder, you're better not to know."

Oh, joy! We have been afloat for 48 hours now, and the pump has yet to go off. I looked - no water, wow! All this was, it was a butt joint and Alan (shipwright) couldn't say whether it was a nail hole or the caulking in the butt itself that was letting water in. Anyway he replaced two nails with silicon bronze screws, and caulked the joint, and it's tight. As is the weepy transducer, all dry now. Also fixed the wee bump on the stem (long delay shifting gears when you have a Gardner idling at only 420 rpm married to a Twin Disc reduction gearbox, more bumps likely in the future) and sharpened up the boot topping (thank you Wayne). Also followed the 'O' Bros advice to reduce the zinc and bonded the remaining anode to the aft bearing housing, thanks to Joseph for your work on this. In a very good space right now.

  1. The thing about the low idle speed causing the long delay is a myth. Gregory Engineering found a broken spring in the selector valve. Replacing the spring has fixed the problem.

  2. In response to articles by Chris McCullen we've now let the zincs go to nothing, and I have recently disconnected the bonding. Chris's advice has to overcome a lot of industrial momentum, but there is no question that he is right: remove your zincs, disconnect your bonding.
