Replacing our Vent Cowls - Again!
We purchased Eximius in May of 2015, at that time it had plastic Vent Cowls and they deteriorated badly in just a few months. Was it something we did when cleaning them? There was always a grotty sticky feeling to the outer surface. I would put it down to UV damage but the boat was in a slip in Port St. Lucie, it should have been no different in our slip in Fort Lauderdale. So, I replaced the cowls in 2018 and again in 2021. They turned grotty in 2023! Two years! And now, four years later they too are grotty and sticky again! Enough! They cost $190 for two, time to remove the lock on the wallet and buy some decent cowl vents.
Initially searching Amazon but really could not find any that would fit the original Catalina Plastic Dorade boxes. Searched the rest of the web, at least it seemed like it, but finally I found Buchan Marine - Cowls - that's what they do!
They have several styles to chose from and I like the low profile cowls, I know that I have leant upon the plastic ones several times, the low profile design should reduce the risk of damage if that happens again.
The Deck plate should fit where the existing vents are and will look a whole lot better. Definitely an upgrade for Eximius.
Perhaps I'll get them in time for Father's Day 😉
I sent an email to Scott Buchan at Buchan Marine
https://www.buchanmarine.net/ventillation and he replied on Saturday evening! He suggested that I confirm the deck plate size, so I'll go down to the boat later today/early Monday and measure the plates. The hole pattern appear to be the same and I did see this pic in their photo gallery images.
That looks exactly like our C34 except the teak is in better condition.
Just an FYI, the deck plate allows the vent cowl to be removed and blanked off. We're in SoFla, and part of our Hurricane prep on the boat is to blank off anywhere that water can get in. Being able to just unscrew the vent cowls and blank the holes off with the Deck plate is a big help. The existing plastic cowls do have a blank, but it's not screwed down and we have used gorilla tape to hold it down during preps for previous hurricanes.
I ordered the 4" Low profile vent cowls this morning ( June 10th 2025 ) from Scott at Buchan Marine:-

BTW, this will make Peggy happy as she detests the plastic ones.
Nice to be adding some Boat Bling for a change.
June 11th, the day after sending an email to Scott at Buchan Marine, I received a reply with an invoice for the total cost and shipping for the 2 vent cowls. PDQ response time.
The invoice is for the two cowl vents with Deck Plate and Cap, two bug screens, and a T handle ( for the Deck plate Cap ) and Shipping. I'll not post the total as I'm guessing the price is going up like everything else.
Update: June 12th. Scott replied to my payment via Zelle. Confirmed the shipping address. So far so good!
I'm not being sponsored by the Company, although I have been chatting to Scott since I placed the order.They are a small business specializing in Ventilation Cowls and have been around for 25 years. As a small business owner myself, I appreciate really good customer service and Scott clearly wears that hat.
Buchan Marine are located in California. But they are not a new startup and have been in business for around 25 years.
Scott just advised me that if you mention Eximius in your order, he will give you a 10% discount
Hopefully, the new Cowls will arrive this coming week. We're planning on some other work on the boat this week after working Monday & Tuesday on a customer's project. We'll install the Cowls the day after they arrive as it should be a quick and easy install.
The new Cowls should ship in the next day or two, seems they do individual QA checks and a final Polish before shipping. I'm getting excited, bright shiny things do that.
So, just to have a comparison, here's a pic of the Starboard side Cowl Vent on the boat:
The plastic really cannot handle the South Florida Sunshine, it's way beyond 'cleaning'
If you notice the Black Dorade housing, it's because I refinished both of them a few years back. Time to make them Boatiful again to honor the new boat bling.
Anticipation is growing.
The insides look pretty grotesque too!
Again, the astute will notice the nice non-skid finish in the pic, that was done earlier this year ( 2025)
Got an email from Scott today, Cowls should ship tomorrow. WooHoo.
Thursday, July 10th. Arrival Day.
Oh My Goodness !
The package arrived a day early, it was waiting on our doorstep when I got home from the grocery store.
The box was heavier than I expected, it took an effort to restrain myself from opening the package before I had stowed the foods in the freezer.
I carefully used a box cutter to open the substantially packaged box, I didn't want to scratch the new Cowls.
WOW ! They are gorgeous. Sorry if I'm swooning with praise, but they really are awesome. You know how it feels when you install a new Stainless Steel Turnbuckle to replace one made in the dark ages? Looks Good, Feels Solid, the shape is amazing. I'm totally impressed.
The package contained the two new cowls, two blanking plates ( Shiny Stainless too ), two bug screens and a Stainless Steel blanking plate key to aid installing / removing the blanks.
Ok, so I obviously have a thing for big bright shiny things, but I didn't realize how bad, I'll have to work on that. Meanwhile, I have to go to the boat to install them. From what I can tell, it should be a simple task of unscrewing the old cowls and installing the new. I'll put some butyl tape between the stainless retaining ring ( very shiny ) and the original plastic/fiberglass base. That's it.
Of course, life events are happening and I'll have to wait till later before going down to the boat. But.... if there's a chance break in the life events, I'll be down there in a flash.
Just picking up one of the cowls brings a smile. I should have done this years ago.
I'll hold off posting this until after the install and I have some pics to show them in place.
In my garage, they look fantastic, growing antsi for the install.
Saturday July 12th - Install Day
Despite the threat of a stormy day, we headed down to the boat to finish another project and to install the new Cowls.
The old cowls were now really gooey, the plastic has been really affected by UV here in South Florida.
It only took a few minutes to remove the screws holding down the old cowls.
I did have to drill holes in the Dorade base as the holes in the cowl's stainless steel base did not line up with the holes either the original holes for the cowls installed by Catalina nor the two replacement plastic cowls that I have installed during the past 10 years. That only took a minute for each cowl.
Here's what we started with. The top of the old cowls is horribly sticky. I was able to rotate the cowls in order to reach the screws in the base.
The new cowl next to the removed old plastic cowl.
This is a significant upgrade and is long overdue. I Should have done this job right when we first replaced the original cowls. At least, I presume they were original, but I'm guessing that as the replacements were in such bad shape after just a couple of years, then the ones in place when we purchased the boat in 2015 were probably also just a few years old.
And this is the result of the new replacement.
Absolutely gorgeous. Super solid, high gloss and they won't fall off.
There's hex head set screw on the inside of the cowl, just a couple of turns with an allen key wrench and the cowl is locked in place.
I am totally pleased with these cowls. They did take a few weeks for delivery but was it worth it. You Bet!
Thanks Scott. I'll send you an email about some other cowls I might be interested in replacing.
Now when I say " See you on the Water " I'll be thinking that you'll know it's Eximius, she's wearing her Jewelry and looks Fine!
See you on the water.
