First Cold Day

We have been watching the boats cruise past with smoke rising from their solid fuel stoves.  However we haven’t lit the solid fuel stove on Kelly-Louise and probably won’t.  However it has reminded us that the temperature is falling.  Jan has been feeling to cold and has taken to wearing two pairs of socks.

Both of us have noticed the cool breeze entering the vents in the front and rear doors.  I’ve probably noticed it more than Jan as I’m the one closest to the bow doors.

Jan made two observations regarding the vents.  The first was our bedroom is in the front of Waiouru so if we have the vents in the doors then we will feel the cold breeze in the bedroom.  Her second observation was how pleased she now felt about our decision to have the saloon in the middle of Waiouru thus avoiding the direct breeze from the front and rear vents.

My assumption is the vents are a safety requirement.  I must ask Andy (the builder) if it is possible to locate them so the air doesn’t directly blow into a compartment.  Perhaps they can be fitted to the exterior of the front and rear bulkheads with the internal vent terminating in the wardrobes and then out via vents at floor level.  Interestingly, I can’t find any specific requirements for the vents in the RCD <here>.  It mentions ventilation/drainage with respect to gas lockers, fuel and water ingress causing flooding

When we woke this morning I would have been tempted to light the stove.  It was overcast and there was a strong breeze.  The wind chill factor was high (for us!).  But by midday the sun was out and the temperature was rising.  If I had lit the stove we would be wasting fuel.

Yes, you can duct the ventilation to exit from the bottom of a cupboard, that's no problem. If you check out Sec 8.9 of the BSS on page 15 of this pdf: it explains it a bit.

Hi Tony,
It's an interesting link and I'm please the vents don't have to be in the doors. However it's also headed a "guide" and it states "advice" and the examiner "may" issue a "warning". None of this gives me the impression it's mandatory. Not that I want to eliminate ventilation.

Hi Both
On Seyella we have vents in the front bulkhead, one either side of the front doors, into the airspace created between the lining and the spray foam on the steelwork. Then we have internal vents on on the last riser on the front steps. The convoluted route avoids draughts, and also encourages ventilation in the void behind the linings, reducing condensation.

Hi again,

Yes ventilation is not currently mandatory, but it's your life that's in danger if you don't follow the guidance. If you look at the October 12th entry on Siskin's blog: you'll see how he's organised his low level ventilation in much the same way as Geoff and Mags describe.

My front vent is a simple letterbox to the right of the doors that then goes down to floor level runs under the bedside cupboard and vents out below the bed when the bed is out from the under the tug deck. When it is really cold you can sense it but judicious placement of a book in the cubby hold above the vent deflects it again.

I'm going to follow all these good suggestions and make sure the vents are not in the door.
