Shhhh! Soundproofing

The Repowering Project: Day 16 (Thursday)

Fine weather at last, but where were we? Stuck inside fitting the soundproofing. So far we've cut all the pieces to do the sides of the engine compartment. Sound simple? Wrong. For a start there are cross-braces, so each side has an upper and lower piece. Then there are all kinds of intrusions - webs coming up from the floor, the shelf for the batteries coming in from the aft end of the compartment, and one side and the floor are angled rather than straight. Much careful measuring, measuring, measuring, crouched in awkward positions in the engine compartment. Then measuring up the soundproofing material, marking, measuring again, then cutting with a Stanley knife, which is hard work - the Vybar we are using is tough stuff. We swapped crouching and cutting roles, so as not to get too much cramp or RSI.

Then you have to wrestle the cut sheet into position behind all the pipes and cables, and correctly positioning the cutouts. For the upper pieces this proved so difficult that we had to cut each one into two. Finally, we had to cut holes in the lower pieces for the access hatches on either side, retaining the cut out bit to stick on the back of the hatch cover. It took us most of the day, with a short break for lunch.

In the process of crawling around and moving pipes and cables, the engineer realised that some more bits of electrical cabling would need to be moved, and that the new exhaust will require a bit of carpentry in the floor of the lazarette to allow it to pass under the cockpit drains. His evening was spent relocating the splitter (a device which allow the alternator to charge two sets of batteries independently).


Keith came by early this morning and attached the adjusted cotton reel to the back of the engine - one more piece in place. We also ordered the through hull fitting for the exhaust pipe - another piece on its way.

Fine weather not entirely wasted - another coat of paint on the Danbuoy.
