replacing tall vetus cowl

[anaisdog]

one of my vetus fresh air cowls left the boat so i wanted to replace both, since the other one is probably original, from 1986, and looks weathered.  i've put in pictures, the opening is 6 inches, for the cowl and 4 inches for the base.  is there any reason not to go with a cheaper and shorter cowl, which is also 4 inches in opening?  it seems i could replace both at 100 each or replace them with shorter ones for 35 each.  I do not live on the boat nor go for more than day sails so i'm not too worried about fresh air exchange. 

thanks

no idea on the one on my boat.  the one i was going to replace it with was a sea dog 901469.  thanks

i'm assuming what i have is    Vetus CHINOOK Silicone Cowl Vent .  I measured the opening, which is 4 inches. I was thinking i could replace with any of the other cowl vents which have the same opening, just shorter height.  any issues that idea?

Leaving your boat unattended is when the air exchange these provide works well.
Mine had mushroom vents inside the dorade so just be careful when you are changing sizes.

I purchased mine through Jamestown:

thanks.  the dorados are fine, its just the top cowl part that was kicked off the boat so i wanted to get two new ones.  which ones, of the cowls, did you go with?

thanks

I replaced the mushroom vents only. The PO had replaced the cowls with tall Stainless Steel ones which love the mainsheet going down wind...

ah.  yeah, i want the low profile ones, so they are less likely to get knocked off

becki,

oh ok, I thought you were referring to replacing w/ a Vetus part number.

nope, just curious if there was any reason a shorter, though just as wide opening, for this cowl, wouldn't work

     Becki,

        I'm guessing you lost it with a sheet whip during a tack, that's when mine would get knocked off. I finally got tired of this and replaced them with "4 stainless steel solar vents, they're very low profile, they move air 24/7 not just when the wind blows the right way, and I think they look better too.

[anaisdog]

which ones did you go with?

thanks Stu, read the article you wrote.  i did replace the mushrooms right after i posted the 2014 article.  was just curious if i could get the cowl smaller, for the opening, but not the base.
