We have been finding large amounts of water on top of the freshwater tank where we store supplies. When we first found it, there there was evidence of the shower drain leaking. We fixed that and leak-tested it carefully so put it all back together. A week or so later, there water on top of the tank again. We’re pretty sure the shower was leaking but it’s definitely not now.

We chased this for a while before finding that it’s coming from the master stateroom air conditioning unit. Normally these leaks are easy to find. If water accumulates in the tank, it’s easy to see and clearing the drain will fix the problem.

In this case the drain is clear and the condensation is draining properly. What we didn’t see was at the back there is an area where dust has accumulated and formed a damn that just includes a small part of the tank below it. Just this section is dropping condensation below. It’s a difficult to get to area only accessible when everything is removed behind the head. From there a panel can be removed and the leak can be seen. Not super hard to fix but quite hard to find.

The 387 ft (118 m) barque Viking, built in 1907, is believe to be the largest sailing ship ever built in Scandinavia. The ship is now permanently moored along the Gothenburg waterfront and is a 3-star hotel,

Here we have the master stateroom HVAC unit detached from the floor and lifted so we can clean it thoroughly and dry the sound insulation below where water has been leaking. The leak was due to accumulated condensation-soaked dust that made a path for a portion of the condenser run-off to run down the outside of the drain pan. James is visible on the other side, where we have the panel underneath the head sink off to access the back of the HVAC unit. This was a time-consuming fix but we can’t complain too much in that in 10 years of use, this is only the 2nd leak problem we have had to chase down.

When filling the fresh water tank, we noticed there was pressure in the tank and the vent was plugged. Here James is removing the vent from where it connects to the tank so he can check the vent is clear both from the hose to the vent vent but also from the fitting to the tank.

Across the river from where we were moored in Gothenburg, we could see several Team Oracle America’s Cup containers probably from the last races in Bermuda. We don’t know the story of how they got here.

An interesting boat design on this trimaran. In an effort to get the speed advantages of a multi-hull without paying the normal width penalty, this boat has hinges that allow the two outer hulls to be folded back up against the main full. This allows the trimaran to fit in a monohull slip but, once it leaves, it can open back up and travel as a trimaran.

A delicious and fun meal at Pinchos Tapas restaurant. The establishment has no printed menus—patrons download their app and order directly from it, entering their table number. Customers are notified through the app when food or drinks are ready to pick-up. The tapas are served on wooden planks that fit double-deckered on holders built into the tables. It’s a casual and fun place to eat, with good food.

Volvo isn’t just about sedate and safe road cars. The company also produces jet engines and Volvos are actively raced. The 37 Viggen fighter, equipped with a Volvo RM8B engine, was one of the most powerful fighters of its time.

The Volvo D16 Euro 6 is a 16.1 liter engine able to reliably produce 550 hp up to 750 hp in different configurations all with a torque of 3,550 Nm (2618 ft lbs). The engine meets the modern Euro 6 emission regulations using Diesel Particulate Filter and Selective Catalytic Reduction. We’re not sure what we would do with a 16.1 liter diesel engine but we know we want one. :-)

A 1979 Volvo B10M bus chassis that was built from 1966 through 2000. This is what a bus looks like prior to the body being installed and many bus builders like Scania, Mercedes, and Volvo sell chassis with all mechanical components installed like this one to bus coach builders like Setra that build finished buses. This puts the major bus manufacturers in the position of both producing finished buses and providing chassis to competing bus manufacturers. The upside is it allows them to target more markets and gives them more opportunities to be the bus manufacturer that a given customer chooses.

The B10M sold 51,492 buses during its 35 years of production. The particular configuration has the engine mounted centrally rather than at the rear of the bus which is more common in highway buses. Mounting the engine centrally requires that the inline 6 cylinder engine be leaned over 90 degrees to fit between the interior floor and the bottom of the bus. Having the engine lying on it’s side allows the engine to be centrally located but leaves the bus interior space unchanged.

One applications of this chassis was a double articulating design from Volvo Metrobus that seats a surprisingly large 270 passengers. Because the oil pan is no longer the lowest point of the engine in these central engine bus designs, they have to run dry sump oiling systems where the oil is pumped out of the engine during operation to a separate reservoir and then pumped from the reservoir into the pressure oil system. Dry sump oiling is also common in race cars where they want to mount the mass of the engine as low as possible and they don’t want high-g acceleration to cause oil starvation as the oil moves around in the oil pan. Putting an inline 6-cylinder engine on its side is a nice solution for the central engine layout common in articulating city buses and many passenger trains.
