Swanwick marina had their annual "Motor Boat Show" thing planned and so they were short on berths, even for little boats like our Nordhavn. We originally wanted to have around 4 days out of the water but this morphed into 10 so that we were high and dry for the boat show time. Actually not a huge issue as the rather high cost of hard standing space is still way cheaper than the exorbitant cost of a visitor berth there. The lift crew are, as usual, a law unto themselves. Maricom asked them about lift timing so they could ensure that the boat was driveable despite all of the battery work going on. No luck, despite them being a commercial tenant in Swanwick.
So, on the allotted day we prepared the boat and waited, while Paul and Mark worked away on some battery installation things. There will be a separate post about that amusement sometime. Then we had a call asking us to go around to the hoist bay and saying that we would drive straight into it and get lifted. Phil and Jess from Nordhavn Europe were on board catching up so they came as extra crew for the long voyage. Only it became way longer as we hovered off the hoist bay for nearly 15 minutes, waiting for a very slow Fleming to start engines and back out. When we entered, one of the hoist crew was plain obnoxious and needed some serious customer handling training, Very very unimpressed. Les, the yard supervisor man who has been there for many years and kind of knew us from when we were permanent berth holders, looked almost sheepish about things and tried to "suck up" a bit afterwards.
Here we are emerging from the salty stuff:
We retired to the Nordhavn office for coffee whilst the boat was being pressure washed and chocked up. This time they did a very good job supporting her - on the last lift here they used only two chocks underneath the keel and we were mightily unamused. The first report is on the effectiveness of the "snake oil" stuff that we applied to the props last year. Amazingly, it worked pretty well. Almost no fouling on there compared to years in which the prop was left bare. The coating still looked OK so we decided to run an experiment and leave it untouched for a second season to see if it was still better than bare metal:
The crystal prop stuff seemed worth the cost and effort, much to our surprise and delight:
Our folding prop on the wing engine needed new stops inside it (when the propeller blades fold out they rest against these and ours were wearing away. As removing the prop assembly is tricky even though we have the big special spanner needed, and giving the whole thing an acid bath is even harder thanks to the size, we asked the evergreen Geoff from Swanwick marine engineers to do that for us. Geoff is a proper old school engineer, in his 70s and is one of the few people we would trust to work on the boat there. Here is the P bracket and shaft, with the prop hub and blades removed
The crew and then the captain with some brick acid did an excellent job cleaning up the keel cooler:
aided by the glorious weather that allowed outside work to continue :
We cleaned and painted antifouling stuff on the bits that needed it. Replaced the bow thruster anodes, greased the seacocks, removed and acid bathed the main engine rope cutter and did some stainless and GRP polishing too.
Inside the boat, we drained down the coolant, and replaced the O rings on the gearbox oil cooler. This is simply put, a messy job and not one that is enjoyable. Luckily it is only needed every 4 years. With the system drained down, the thermostats were removed:
and then replaced:
as preventative maintenance. They were getting on a bit, like the captain and crew really.
We'd been waiting on some more coolant to arrive as we planned to swap out the main engine stuff early, to save having the job when, possibly, we don't have a car and access to a council refuse site to dispose of it. That became a comedy of errors - the 20 litres of pre-mix we ordered on line prompted a message from the supplier saying that when they went to the warehouse, they found their stock computer was wrong and they had none. So, we decided to order the 20l of concentrate they had instead, after negotiating a better price as they wanted more for it than 2x30l of premix. We pointed out that we also had to procure the distilled water and so....
We were told that the concentrate was "on the way" but the courier kept saying that they didn't have the parcel yet. We contacted the supplier who promised to chase them. Another message and they assured us it would be shipped and delivered the next day. Sure enough, it was but it arrived as pre-mix the stuff originally ordered, not concentrate.. A credit later we at least had some coolant but we also now own 20 litres of distilled water and a 10l drum to mix it all in. This little saga burned many hours.
We could then drain down the entire system via the keel cooler and refill it nice and slowly. The cleaned up wing prop with new stops was refitted with tons of grease inside it, anodes fitted and the boat was pretty much ready for relaunch:
Inside, the stabilisers had a top end overhaul (new bearing surfaces, hydraulic oil and filter change and at long last the pressure gauge was swapped for a test port that the captain had bought ages ago. Pressure gauges are known to fail in a nice spectacular way and we didn't fancy mopping up all that messy oil coming out at lots of PSI. We also fitted a new pressure switch - the manufacturers of the system, told us that the older unit had a history of failing as they aged and ours was nearly 20 years old. Again, we'd bought a replacement a while ago and that was fitted too.
Finally, the Seafire fire extinguishing system was checked and certified OK by the dealer, Golden Arrow who also did a chunk of the stabiliser work for us as the fins have a sensor that needs to be realigned after the new bearings are fitted. Very luckily as it turned out....
During all this fun we stayed with Ann and Martin who live very close by. An excellent B and D service indeed, plus a couple of Toddlerville trips to take Mrs T to her normal spot - the Southampton hospital eye department and on a little shopping spree.
Les, the boatyard man was most accommodating offering us a choice of times for relaunch. The tide times were less than ideal so we expected some fun getting into a berth afterwards. We popped into the marina office the evening before the 7:30 am relaunch to ask about where they wanted us to go for a couple of nights once back in the water (pre-booked by Maricom) and were told to "ask again in the morning". What could possibly go wrong?
