Who ever uses marina loos or showers?

[RichardS]

We have a 110HP tubocharged Yanmar. The boat has a huge calorifier. It takes 40 minutes of motoring or 1 1/2 hrs. of running light to heat the water.

I'm surprised that a large engine which produces a huge amount of heat even at tickover would take so long to heat up the water, bearing in mind how quickly the block on most engines becomes too hot to touch. I wonder whether some calorifiers are connected to the heat exchanger side of the thermostat rather than the block side?

I strike up the genset where it takes 30 minutes.

I will not leave my main engine running light for hot water or battery charging, hence the genset.

I too am reluctant to leave my engine running without load. I have been forced to do so quite enough while negotiating the Dutch canals. It is a FW-cooled V2030. I suspect that the temperature difference between the Med and Essex may account for some of our differences but I am fairly sure than 1/2 at idle won't allow me to have a shower even though normal running will make the water piping hot.

One of the advantages of keeping a boat at a marina is that I have an additional place where I can take a shower. During the warmer months, I often do a 5K run at a park near my office after leaving work. The marina is much closer to the park than my home. If I have errands after my run, I go to the marina to take a shower and change clothes. The shower is in a building that is little more than a shed with concrete floor, but it fills the need.

Is that 28 hp and a 24 l calorifier, may I ask?

You may indeed ask but because of my ignorance you may not get a satisfactory answer. The engine is actually 27hp for what it's worth but I can't offhand remember the calorifier size.

Standard for an HR34 seems to be ca. 24 litres, but I presume other sizes were optional. Calorifier size is obviously important but had gone unmentioned. I have never run our engine (18hp) at idle just for hot water (a 1kW immersion heats 22l in about 45 minutes) so I shall not expect too much if I do. Thanks.

In most of the marinas we visit, a bit of shampoo in the water will only improve the environment - help to dissolve some of the spilled oil and diesel!

Yes. I guess the culture of "what is accepted behaviour" varies quite a bit from country to country. People over here are sometimes a bit too eager to frown upon what other people do (whether it has any substantial ecological impact or not).

Shower water is basically clean water compared to the water coming from the galley sink.

Yes, probably so (at least with some ecologically sound soap/schampoo)! What about the sink water, then? Do people over there generally just let it flow out in the marina? Guess so?
