Why No fan in the heads? Oyster, Hallberg!

[Jamesuk]

So i have been onboard some of the finest yachts in the world and the sailing boats from Oyster and Hallberg Rassy being two examples of top flight luxury yacht brands and still you walk in and they have no fans in the heads/toilet area's. An extracter fan would be at least the minimum, beacuse to many the courtosy flush is beyond them.

So why do boats not have fans in the heads. You see them all over the place on some boats but never in the heads. Why is that? Above say 110 feet AirCon runs all the time on smaller boats its on occasionally.

PS
A lil experience: I worked in Vietnam about 7 years ago and i was introduced to a long standing joke by the business agent there when it came to going for a number 2. "Right just heading off to the Sofitel Hanoi." or "Nipping up to Jacks bar for happy hour.."

Why did we go because in these 5 star hotels they have air conditioned toilet areas so when wearing a shirt and trousers the last image you wish to portray to someone is that you appear to have just gone out for a run, sweaty and potentially smelly.

Ahh good times Hanoi.

I looked into this when we were specifying the first Rustler 44.

The problem I came up against was that I couldn't find a 12v unit that had watertight integrity. The only solution I came up with was a fan on a hinge bracket that could be swung across over the lewmar hatches or portlights.

We didn't install them in the end, but when certain people are on board (you know who you are) I sometimes regret my decision.

Smaller Finngulfs come with two Niacro (Marinco USA) solar powered vents, one on each side, head and aft cabin. I was originally a bit dubious about them but they still are running after five years and shift a fair bit of air, they run when the boat is sitting not being used drawing air right through the accommodation provided the doors are open without draining the batteries however they do not run at night or under cover in winter so I have had to make a winter washboard with louvres right down it to maintain the through flow.
For a boatbuilder from the cool Gulf of Finland Finngulf seemed obsessed with good through ventilation. A screw down mushroom on the foredeck in front of the forehatch, another hatch and big dorades incorporated into the hatch garage over the main cabin for a designed airflow from forward to aft. All the coachroof windows are openable too and the boat came with flyscreens for every hatch and window, though in Scotland our insects are not voracious enough to bother fitting them. Their bigger boats are even better ventilated.

Large boats with a lot of electrical power don't really have any excuse, this is the 21st Century and we're all supposed to travel by jet pack, wear silver one piece suits and have a protein pill for lunch, so what's so difficult about extractor fans for loos ?!

I would say though one has to be careful about certain fans, I asked a salesman at the Boat Show if his solar fan ( which charged a battery so it worked overnight too ) was 'spark-safe' to use in the fuel locker; " Oh yes, Spiffingly So, Sir "

I learned later that this thing was totally unsafe and we were lucky not to be already in orbit, he was probably basing his sales pitch on the theory " We've never had any complaints, just heard the odd rumour about explosions "... this may apply to Methane emissions too, which can happen even on Hallberg Rasseys !

Also the standard 'tannoy vents' are not green water proof, go for the jobs with an internal collar which closes them off in heavy weather.

One idea for loo fans may be the sort of 'bilge blower' things mobo's use to ventilate explosive fuel from the bilges, and I'm only half joking !

Obvious. Those who can afford Oysters simply dont fart like the rest of us. Its pre scented with roses.

Wow, so my 24-footer beats all those expensive yots?

There's a fan in the heads bulkhead, pulling air out into the machinery space under the cockpit, ultimately to escape through a vent in the cockpit locker lid.

Of course, I've never actually used it, as the heads compartment is too cramped to attempt a no2 except under the direst provocation. I'd rather use a bucket in the cockpit.

Pete,

this is of course complete common sense for blokes, just before First Date With Potential SWMBO; in my experience the bucket is the better option but there's always hope.

Solar vents have their place but they do not solve the venting the heads problem.

Does that mean you cannot take a d**p unless the sun is out?

Me, I have trained my bowels to move in the morning when the fan is buzzing away overhead, to be frank I usually open the window as well before sitting down.

Is 'dump' a naughty word or are you just extra prudish?
