Cowl ventilators

I own a NS36 and I am looking to replace my 4 roof cowl ventilators. I would like to replace the chimneys only since my dorades are already installed and function well. These chimneys are the slip-on type. Are they still available on the market?

Stright-Mackay sells the Vetus cowl ventilators Chinook (4’‘) silicone for $125 each or the TOMS (4’') PVC for $134 each. Both of these come with the plastic ring nuts and the mating deck flanges. Does anyone know if they fit the NS dorades and templates?

Should I go with silicone or PVC? The old ones are pretty discolored and yucky. Thanks.

I replaced mine this year after one accidentally went overboard. This was the best price at the time for a white PVC.

Thanks for the info Will. I’ll check to see if the Sea Dog line is available in Canada.

I’ve had fantastic luck spray painting a flexible cowl. Used special paint (available at Home Depot). Three years now and it still looks like new.

Jim -

Do you know the name and type of paint that you’ve used on the cowl ?? Is it a lacquer, by any chance ?

Ernie,
It was a Rust-oleum but it specifically said for plastics. The cowl I painted looked like trash and I just took a chance. Surprised myself in that it came out looking like new.

Wow …

On a (white, presumably) plastic flexible cowl that gets gooey and sticky halfway through the summer ?? How fantastic is that !!

Thanks, Jim.

I keep ours looking new with 3M wax/cleaner...

I clean my flexible cowl vent (very quickly) with acetone.
