Bed wetting?

Temporary fix?

Get some cheap plastic containers.

Cut a hole in each side with a hole saw.

Place over "mushroom vents".

Put something on top of container to weight it down so that it doesn't blow away.

Seen this doen with large plantpots. Works very well I am told. Obviously sufficient holes needed to equal vent area.

Said it many times, but if I built another boat I would have no holes in the roof whatsoever.

IMHO, the location of vents, like windows, should only be finalised when the internal layout has been fixed, so vents can be located above corridor areas and not beds.

 

They will always tend to drip, from condensation if not from splashing rain.

Mine have never dripped. Am I doing something wrong?

It could be that it's condensation dripping from your vents. To cure that get some plastic drainpipe of the right diameter and shove it up the vent being careful not to restrict the ventilation. That insulates the sides of the vent duct and reduces condensation. Worked for us

If you have a grille below the vent inside the boat then remove it. Next time it rains get a torch and have a good look to see what is actually going on.

 

A few condensation drips are to be expected in some weather conditions.

 

If you think the leak is from a badly fitting base then do a temporary repair with silicone type sealant round the outside of the base.If this fixes it then do a proper removal and refitting of the mushroom in the spring when the weather is drier as it will likely involve some rust removal and priming of the bare metal.

Condensation is usually the problem - with brass or steel vents you cannot avoid having a 'cold bridge' The building industry spends thousands of pounds avoiding having them in all manner of buildings. The easy way is to suspend something to catch the drips under the vent - on Dasque I used a turned wooden dish suspended on three wires it worked well.

Thanks guys. And I'm my case it's torrential rain. Im off to BnQ at the weekend to get a couple of heavy plant pots. Will drill them round the sides so the air still gets in. This sounds like a very workable fix. I've read all the advice, but sounds like a better option than hanging something inside ;)

Alternatively, there is material on the market generally known as knitmesh, it is a loose woven fine metal wire supplied in coils of various lengths and widths in stainless steel, copper, brass, etc, (the stuff they use to make pot scourers etc) that can be cut to length and rolled into cylindrical filters off suitable diameter (3, 4, 5 turns to make up the required thickness).

 

Placed around the outside edge of the flange on the roof, then being held in place when the dome is screwed down slightly squashing the mesh - but to a higher level than before to compensate for the loss of area due to the space taken by the wire itselff - but it will stop the splashes of rain.

 

Unfortunately, it is a specialist material and not the sort of thing likely to be sold in domestic shops - although a BnQ Superstore might - but if not, then readily available on e-bay.

Obviously not for nothing did working boats have much taller mushroom vents fitted.

And far fewer of them! But this worked on Warrior too. More sophisticated might to be a disc of some flat but absorbant material that could be slotted round the vent and thus less liable to blow away (or hamper ventilation). It doesn't need to absorb the water (i.e. it doesn't matter if it's soaked through), just the impact to stop it bouncing.

fix a funnel under the vent, attached to a flexible hose, which should be connected to the air vent from your water tank. any time water is drawn off from the tank the vacuum will suck out any water from the hose.

 

this way you get a proportion of your water supply as clean distilled water which is a GOOD THING.

 

alternatively just run the hose to the battery compartment, remove the filler caps and arrange some distribution hoses to constantly replenish your electrolyte.

Or store it for that next coolant change ;)
