Winterisation round-up 2017

November 17, 2017

Following crane-out there are a number of winterisation tasks on my to-do list. The one that I always tackle first is hosing-down our Macwester Malin’s hull to remove the worst of the season’s fouling. This year, as can be seen above, there was heavier weed growth than I’ve ever witnessed (on our yacht).

Still, nothing that would cause any problem to our type of sailing, and certainly much less than the growth that I spotted on our chum’s Colvic Watson earlier in the year [above]. She sported a rather impressive matching goatee-beard at the pointy end too.

Next up is swapping out the impeller, flushing away the salt water, and filling our Lombardini diesel engine’s cooling system with anti-freeze. I didn’t bother swapping out the impeller this year, as I plan on buying a new one for the start of next season.

When it came to winterising our Lavac heads, I thought that I’d try something new. The idea was to ensure that there was no water left in the system, including the intake. With this in mind I shoved a length of hose (kindly provided by Calloo’s skipper) up the inlet.

The other end was positioned with care in a strategically placed bucket of anti-freeze. All I needed to do was nip on-board and pump the anti-freeze through the whole system and the job would be done. Unfortunately, this didn’t work despite various adjustments. There must have been too much air leakage to enable enough suction in the system. This is something I’ll need to improve upon for next year.

We remembered to bring one of the children’s sledges with us to drag the Hippo buoy through the mud. That goes some way to reduce the energy-sapping nature of removing our mooring ground tackle for the winter. Despite that, this year, the crew put in too much effort and jiggered her back.

Above; note the promenade wall that was a feature of the previous post [see here].

While I’ve still to brim our Macwester Malin’s fuel tanks, and complete one or two other tasks, the biggest item remaining on the pre-Christmas to-do list is to address the gearbox problem. While some might just put the loss of gears on the last day of the season down to a glitch, I’m not the kind of skipper who’s comfortable taking a gamble on that sort of thing …so it looks like the gearbox might have to come out to see if any remedial work is required. Yay!

  1. Have you checked the oil level in the gearbox if its low the gear box doesnt work

    • Hi Alan, Thanks for your suggestion. The simple answer is yes and no. Yes I checked the oil at the beginning of the season, but no I haven’t checked since …so that’s certainly a great place to start – thank you. I’ll check the oil before doing anything else. With any luck something has changed between crane-in and now. All the best!

      • We bought our Malin new in 1988 Sail Ni 248 in those days the gearbox had an oil filter. If you went hard to port or stbd the steering mechanism impinged on the filter bending it so the seal leaked oil into the bilge. No oil=no gearbox. The engineers could see no reason why it needed a filter, so ditched it and plugged hole with a bolt of right thread.

  2. You mention Brim the tanks – does this mean you fill them to the brim. Why not empty them and flush them out.??

    • Hi Robert, thanks for your comment. Yes I fill the tanks to the brim. Our Malin may well have had replacement tanks at some stage, but they’re mild steel rather than plastic or stainless 316. Emptying the tanks is a lengthy process [ see https://macwester.wordpress.com/2017/03/20/fuel-system-overhaul-2017/ ], so standard practice in our neck of the woods is to brim the tanks to reduce/prevent condensation from forming …as condensation obviously leads to water that settles at the bottom of the tanks and corrodes over time. So to recap, it’s much less work to fill the tanks up than drain them. All the best!

  3. Re filling tanks over winter make sure that there’s no water lying at te bottom. Bugs love growing at a diesel/water interface and they form a sludge which bungs up pipes and filters.

    • Hi Alan, thanks for your comment. I overhauled the fuel system before the beginning of the 2017 season [ https://macwester.wordpress.com/2017/03/20/fuel-system-overhaul-2017/ ]. It was a job that needed doing, as I didn’t know when it had last been done (and we bought our Malin in 2011). There was no sign of diesel bug, but there was surface rust at the bottom of both tanks, so it’s reasonable to assume that water had been there. I always put in an anti-diesel bug additive when I’m putting diesel in the tanks, so that might help along with the low temperatures up here. All the best!
