Amsterdam First Two Weeks


Click for larger image

During our first two weeks in Amsterdam, we enjoyed being back in familiar territory with the city already lit up for the winter. We revisited some of our favourite restaurants, found some new ones, and stocked up on supplies and parts from known vendors. We also completed a fair number of larger boat projects, including changing the wing engine PTO clutch, bolting the Freeman hatch in place, and replacing the hydraulic steering rod end.

Below are trip highlights from November 2nd through 18th, 2019 in Amsterdam. Click any image for a larger view, or click the position to view the location on a map. And a live map of our current route and most recent log entries always is available at mvdirona.com/maps.

Window Covers
We have mesh covers for our pilot house windows that we use for sun protection and privacy. We’d kept them in a covered bin in a bow locker and it looks like condensation built up on the inside and we had some mildew on the covers. We got most of it off with a power washer spray and scrubbed off anything more stubborn with a hand brush.

Changing Clutch
Today we changed the hydraulic power take-off (PTO) clutch on our Lugger L844d wing engine. We documented the job in this video, where we show the problem with the PTO clutch and how to change it.

Defrost Flow
The defrost vents above the dash for our diesel furnace weren’t producing enough heat. Here we’ve got the flybridge brow emptied so James can check for issues at the ducting inside that feeds the dash outlets. He found the furnace heating water going to the defrost heat-exchange units was cold, indicating there’s an air lock in this part of the circuit, or some other problem is preventing coolant flow.

Furnace Manifold
After James found there was no hot water flow in the pilot house defrost heating circuit, he went down to the furnace in the aft port corner of the lazarette to check for flow on all cooling circuits at the furnace. He found that the yellow handle roughly in the center was in the open position, allowing hot water to partially bypass the heating circuits. The unusual thing is the system mostly still worked acceptably well. Even the defrost system still worked, it was just slower to heat.

It seems the pump moves enough volume that, even with a large bypass open, it still operates, but just less effectively. Looking back at our pictures over time, we can see that this valve was originally positioned correctly. But the weird thing is we haven’t been back in this area hard-to-access area for a couple of years. It must have been inadvertently bumped, and probably quite a long time ago.

Canvas Snap
Over the years, a few of the snaps that secure our canvas to to the boat have broken. We recently bought a Snap Setter, snap fasteners, and snap studs and have been replacing broken snaps as we find them. One of the snaps for the engine air intake covers had broken, so we replaced that today. When we’re moored for a while where the weather is cold, we cover the engine room air intakes with custom canvas covers to keep the boat a little warmer.

Temporary Admission
Dutch customs came by today to inspect our paperwork and give us a new Temporary Admission document for Dirona. This establishes that we have VAT-free temporary admission of the vessel for 18 months since re-entering the EU Customs Zone from Heligoland. The paperwork isn’t necessary, but we prefer to have documentation of the boat’s VAT status to avoid potential hassles and delays in the future.

Freeman Hatch
If you ever see a Freeman hatch without screws or mechanical fasters in the top flange, then it’s not mechanically attached to the boat. Adhesives are used to hold windshields in cars and even windows in boats, so can be excellent and can last well.

But we just couldn’t convince ourselves that we wanted to rely exclusively on adhesives in this case. If the hatch came off in a storm, the boat would likely be lost. If the wrong adhesive was used or it didn’t age well, we could have a problem. An earlier Nordhavn 47 had experienced a hatch detaching, so we decided to play it safe and bolt it in place.

Here James is marking where to drill holes for evenly-spaced bolts where each hole is through heavy structural material and will hold securely.

Drilling
Drilling bolt holes in the Freeman hatch to secure it mechanically. This is surprisingly easy, but hard to do without worrying about making a mistake in placement.

Hatch Secure
The Freeman hatch now is securely held in by six bolts rather than adhesive. It’s not going anywhere.

Bubble Barrier
The recently-installed Bubble Barrier in Westerdok minimizes the amount of garbage that reaches the sea from Amsterdam canals, without impeding boat traffic or fish movement. Compressed air is fed through a punctured pipe lying diagonally on the bottom and the resulting bubbles push garbage to the side of the canal, where it collects in a floating platform. Its a remarkably simple design and from watching it, one that really seems to work. Brilliant!

Parts or Machine Shop
On Dirona we have a Teleflex Capilano steering system. The steering cylinder is Capilano HC5378 and we need just the rod end for this cylinder. The rod end is a bit unusual in that it combines a 3/4-in ball hole with a 7/8-in 14 thread-per-inch shank where 99% of the rod ends combine a 3/4-in hole with a 3/4-in 16 TPI threaded section. The picture above is of both these parts. We need to either find a source for the correct part or a machine shop in the Amsterdam area that can drill the 3/4-in hole out to 7/8-in and thread it at 14 threads per inch. This one is proving challenging.

We would appreciate any recommendations on Teleflex parts suppliers that might be able to get us what we need or machine shops in the Amsterdam area that could drill out the common part to the size we need.

Update 11/14/2019: This one is solved. Thanks for all the suggestions.

Fender
As part of our fendering redesign a couple of years back, we purchased four EasyStore 42x132cm fenders. They’ve performed well, particularly through our 97 lock passages this year, so we ordered one of their larger ones and it just arrived today from Amazon UK. At 24×59 inches, it’s a beast. And it cost only £175, about half the price of the smaller 24×42-inch Pro Stock marine fender we currently use at the bow.

Damaged Breadboard
It’s only 5 volts, but a year back we made a wiring mistake on this one and the breadboard was damaged. We weren’t intending to change it, but the board comes from a batch that weren’t great. So, the combination of the thermal damage and this being a low-quality board, led us to replace it. The new board even feels better when installing jumpers.

Junction Box
This is the junction box with the new breadboard installed. This junction box doesn’t really have many connections but it’s enough to look busy and to require some care when changing the breadboard. Passing through this junction box are:
 • matrix 4×4 keyboard connection—8 wires in and 8 out
 • Lax I2C bus—4 wires in and 4 wires out
 • I2C to 8 pin digital I/O—4 wires of I2C and 5 signalling connections to sense:
   ◦ Digital in: Gen Autostart off/on
   ◦ Digital in: I2C bus off/on
   ◦ Digital out: Blue autostart warning light
   ◦ Digital out: ER Yellow warning light
   ◦ Digital out: ER Red warning light

Weatherstripping Reinstalled
We removed the Freeman hatch cover and brought it inside to reinstall the weatherstripping. It’s easier to work with the cover level, and the adhesive works better at room temperatures. Here the weatherstripping has been reinstalled using Loctite 37532 Black Weatherstrip Adhesive.

Steering Maintenance
Today we removed and replaced the hydraulic steering rod end. In the video at https://youtu.be/3kAtUMZ3_kk we step through the steering system on the Nordhavn 52, showing some of the wear points and the changes we have made to minimize these issues. Finally, we show the removal and replacement of the hydraulic steering rod end. This is the part that transfers force between the hydraulic cylinder and the steering arm. We show how to check for wear and change the part.

Oil Delivery
The five 20L pails of engine oil that we’d ordered from Amazon Germany just arrived today. (Well, four of the five did, the fifth came the next day.) That folding cart continues to get heavy use on Dirona.

We’d used every drop of oil on the boat, so this 100L delivery takes us from empty to back to full capacity. This will maintain all of our engines for about a year under normal use.

Rimula R4L
Obtaining circular pails is getting harder in many geographies, where each company is using their own proprietary-shaped 20L container. We need secure storage when we’re in rough waters, so it’s far easier for us to use a standard shape. We try to get ACEA-E9 whenever we can, but sometimes can only get ACEA-E7, which meets the specs for our engine and is acceptable, but is not our preference.

Tender Battery
It’s time to replace the tender start battery. This particular battery is nearly four years old and spent most of its life as a spare battery in the old tender and then was moved over to the new tender, where it has been in use for about a year. Technically it still starts the engine well, but it tests as needing replacement due to waning capacity.

Fixing Prop
We love exploring in the tender and frequently touch bottom. We’re not too concerned about that, since a new propellor is only $90. But to maximize propeller life, James periodically straightens out the blades and files them smooth. We typically average around a year’s use on a prop.

Watermaker Maintenance
Today we completed a number of maintenance items on the water maker. We changed the high-pressure (HP) pump oil, greased the HP pump motor, backflushed the media filter until clear and changed the carbon and 5-micron pleated filter. In the picture, James is pumping out the old oil from the HP pump.

Old Filters
The old carbon filter and 5-micron pleated filter from the watermaker after changing. The last change was about ten months ago.

In high plankton areas like North America’s Pacific Northwest, having to change the water maker prefilter once a day is not uncommon. This can get tedious, so we ordered a simple solution. In front of the standard 5-micron pleated paper filter, we have a media filter.

A media filter is essentially a large vessel full of carefully-selected sand. This approach is the most common approach used in swimming pool filtration and is very effective. We can run the water maker full time for 2 to 4 weeks until the filter begins to show signs of needing to be cleaned.

On ours, pressure gauges on the inlet and the outlet allow us to check the pressure loss across the filter. It’s pretty simple to clean when needed. Rotate the inlet and outlet valves and turn on the media filter booster pump to backflush the filter. After a couple of minutes, it clears and the process is done. Restore the valves and it’s ready to return to use.

Before using the media filter, depending on water conditions, the media filter might need back-flushing weekly, or it could be as long as a month. With the media filter we only need to change the prefilter annually, even when in heavy use.

Antifreeze Leak
We had developed a slight antifreeze leak under the main engine and could see a drip from one of the coolant hoses that run out to the keel cooler. So the hose clamps likely needed tightening. Unfortunately they are all under the engine on the port side, and the only way to access them is reaching across from the starboard side where you can’t actually see what you are doing. This picture, taken looking aft from underneath the front of the engine, shows James stretched out to arm’s limit and working by feel to place a wrench on the nut to tighten it.

Our experience with heavy wire-reinforced hose is that well-installed clamps will still probably need to be tightened after one to two years, but after that it usually is fine for the life of the boat. That’s the good news. The bad news is these particular clamps are just about completely impossible to access. The entire job took several hours, and the most difficult hose clamp was two hours all by itself.

James has worked on Lamborghinis, Ferrari and other Italian exotics not known for ease of service, but has never found a hose clamp as difficult to access as these four. Fortunately one of the upsides of Nordhavns is they’re designed to be used and serviced, with few parts that are actually “built-in”, so this is a rare problem on Dirona.

    Wow, your preventative maintenance is very extensive, exhaustive and impressive. I can see why you have suffered so few equipment failures over many years of voyaging. Good idea to bolt down the Freeman hatch even though the company believes adhesives alone are strong enough. Belt and suspenders attitude.

    I am a bit surprised that Nordhavn built the boat with critical coolant hoses that are so inaccessible. One of them took two hours to tighten with a cool engine — would it be impossible to service them if the engine was hot? Wire-reinforced clamped hoses may be good enough to last the life of the boat, but they still seem like an item that should be more repairable.

    • These hoses are remarkably challenging to service but it’s a rare point. I’ve seen some terrible things in the boating world where engines and other components are installed before the boat is fully built and they simply can’t be serviced. There are some ugly things out there. These hoses are silly difficult but they are a rare design point and we can’t blame the manufacturer on these ones since they were installed 7 years after the build. Prior to replacing these hoses when doing some keel cooler work, I never even knew about these 4 clamps. It leaked immediately after the work, I tightened them up and they went 3 more years. Now that I’ve tightened them up again, I suspect I’ll not need to go back in there unless the hoses are changed.

      If these hose clamps leaked at sea, I agree they would be very tough to tighten them in a rolling boat with a hot engine. But, you can manage even fairly large leaks by just adding water to the coolant reservoir as a temporary measure. It wouldn’t be a problem but, of course, they really shouldn’t be leaking and I’m glad they are now sealed up tight.
