Bob692 Posted December 11, 2019 Report Share Posted December 11, 2019 Are low profile vents BSS compliant? I am thinking of fitting a couple of these where I am going to fit solar panels, so the can lie flatter. https://www.midlandchandlers.co.uk/products/vent-mc-tannoy-9-s-s-13509-av-112 Link to comment Share on other sites More sharing options...

(Doesn't necessarily mean they comply, just that the examiners think they do) Edited December 11, 2019 by Alan de Enfield Link to comment Share on other sites More sharing options...

I understand removing the fly trap screen will give a larger area and putting spacers on the screws even more but as you want low profile the latter is not relevant.

OldGoat Posted December 11, 2019 Report Share Posted December 11, 2019 Yuk! Only suitable for plastic cruisers. No respectable narrowboat owner should use them. Proper mushroom vents are the only proper solution... Times change....... Link to comment Share on other sites More sharing options...

Never have understood the need for brass mushrooms that either look terrible or need constant polishing. 1 Link to comment Share on other sites More sharing options...

Bob692 Posted December 11, 2019 Author Report Share Posted December 11, 2019 (edited) I wondered why most boats these days have mushroom vents.......... So its a traditional/fashion thing. Even if they are infra dig they will be hidden under my solar panels and solar panels are hardly traditional but they are practical. Now I need to go a feed the horse thats pulling my boat.

Kendorr Posted December 11, 2019 Report Share Posted December 11, 2019 Fitted 4 UFO vents on my new build, absolutely fine with BSS. Link to comment Share on other sites More sharing options...
mrsmelly Posted December 11, 2019 Report Share Posted December 11, 2019 I didnt think vents were obligitory anyway? Just advisable? Link to comment Share on other sites More sharing options...

There's something about having to have hog and low level ventilation (and when I built) there was nothing terribly specific in the original BBS manual. Hence I made my own decision and studiously provided both. I didn't care for the caravan type vents and IIRC liners or finishing plates weren't available - so went for 'proper' brass thnigies made by someone in Leicester - another 'traditional' metal worker, long since gone. Standards change - hey ho. Link to comment Share on other sites More sharing options...
system 4-50 Posted December 11, 2019 Report Share Posted December 11, 2019 If you're fitting UFO vents, rejig the fixings so that you have 4 holes in the roof rather than umpteen as the standard fitting requires. They are far from ideal in many ways. Link to comment Share on other sites More sharing options...

They are far from ideal in many ways. Mine only have 4 screws - at 2 o'clock, 4 o'clock, 8 o'clock and 10 o'clock. I have found them "ideal", fully waterproof and 'sea-worthy' even when waves break over the roof. Link to comment Share on other sites More sharing options...

As has been said previously - the BSS has no 'say' over ventilation in Private boats (commercial boats is a different matter). They can suggest that it may be better to have more ventilation but it is not a 'fail' not to have any ventilation. Link to comment Share on other sites More sharing options...

It is well worth reading the BSS guidance so you are in a position of strength when your Examiner fails you on something that is not madatory. Each section of the BSS has a letter in the top of the section 'box'. It will be either an A or an R A is 'advisory' and your non-compliance means it is not a fail just "in our experience it is better if you do it advisory", or R which means it is required and mandatory.

David Mack Posted December 11, 2019 Report Share Posted December 11, 2019 Once you get dirt under the dome of those things you can't get it out, short of removing the domes (which involved drilling out the pop rivets in my case). Once the dirt accumulates, moss will start to grow in it, this in turn holds water, so the paint below fails and the cabin top starts to rust. The rust then creeps under the plastic inner part, eventually allowing water to leak through and drip into the boat, and further supporting the growth of plant life in the space between the vent unit itself and the inner cabin lining trim... I have removed mine. Link to comment Share on other sites More sharing options...

cuthound Posted December 12, 2019 Report Share Posted December 12, 2019 An alternative to the UFO type of vent, which eventually leaki s a low profile mushroom vent. https://marinestore.co.uk/Merchant2/merchant.mvc?Screen=PROD&Product_Code=veportos1&gclid=CjwKCAiA58fvBRAzEiwAQW-hzTlocH1UaSjlboRelnNnbh7WENrlEfkfa_fN2p171WrY5lv8Si3uFxoCJd4QAvD_BwE Link to comment Share on other sites More sharing options...
