Title: Blocked Deck Scuppers
Post by: britinusa on June 23, 2017, 08:44:45 AM
We keep Eximius at a Dock in a residential area, there are trees on the property and they drop lots of 'Stuff' such as seeds, flowers and bits of hair like bark (they're varieties of palm trees) and this flotsam clogs the deck scupper, so we end up with dirty water laying on either side of the scuppers. After a heavy rain (and this is South Florida) it's even worse.

Even though we visit the boat several times a week, it only takes a day for grot to build up and we have to rinse / scrub the area near the scuppers.

Our boat is not the cleanest of boats top sides, we know it needs work, but the scuppers getting blocked every week is a pain. Yes we get the black marks on the sides below them.

I was thinking of expanding the scuppers, they look to be about 3/8" right now and wondered if it would be reasonable to drill them out and line the insides with GFP to water proof the toe rail.

There are several articles on putting tubes into the scuppers to move the pour point further from the boat, but our problem is water not being able to drain when the block.

Ideas?

Paul,
I had the same question although my scupper clogging issue doesn't sound as bad as yours.  See attached link. I was warned off expanding the holes.  The idea to add clear plastic tube doesn't help with the fact that the deck scupper holes are too small.  I've lived with it.

I drilled mine out many years ago and it worked out great.  I used epoxy to seal the newly cut areas of the toe rail.

Ken, do you have any pics?

Paul, IIRC Ken just made a bigger hole.  Have you considered putting some kind of screening over them? Kinda like over a downspout at the end of your roof gutters on your house?

Stu, yes, I wondered how I might do that.
Haven't come up with a method or material yet.

The amount of vegetation that falls on the boat (that and Iguana Poop) is considerable and regularly blocks the scupper holes. That tends to leave a grotty black/brown residue and the scuppers full of debris & water.

If there's considerable debris forming a grotty black/brown residue it doesn't sound like a bigger hole is going to solve the problem. Why not put a tarp/cover over the boom to or over the port and starboard lifelines? Something inexpensive at first to try it. If it does the job upgrade to something "shippy".

Paul : Go to a bigger hole and be sure to seal the new hole cut with epoxy.  Then you can use a larger tube to get the water away from making a dirty mark down the side.

A thought

Paul, I don't have any pictures as I sold the boat a number of years ago.  As Ron said, just drill it and then coat the newly cut surface with epoxy.

Thanks guys.
I was cleaning the hull today and noticed that the holes appear to have a tube stuck into them that is perhaps less than 3/8" diameter.

Going back to the boat in the morning and will see if they come out.

Paul,

Obviously, the answer is......... be on the boat more often!   :thumb:

Agreed! We feel it when the boat is still tied to the slip with two week old knots.

Then again, we have been pretty busy on the boat, the hull cleaning is really the first chance I have had between house and boat and, most importantly, our 3yr old Granddaughter, in 2 years. But the hull is looking really good.

Off to do the other half today.

A dock mate had the yard professionally sculpt the scuppers leaving a open shape. I drilled one out to see what was there and found the gunnel to be solid glass. Bored all 4 out to 1" and "painted" epoxy resin inside the hole. Works great!

What is your boat's year and hull number?

2nd that Q.

Not sure if our 87 would allow that, anyone got a pic of the deck/hull joint on a Mk 1 ?

When looking at adding an outside t-track for downwind sailing I talked to Warren Pandy at Catalina. He sent me two PDF's. Unfortunately I can't attach here due to the file size. If you send me a PM with your email I can send to you via email.

Jon, can you post them on the wiki and add the link here?
Title: Re: Blocked Deck Scuppers
Post by: Jon W on July 01, 2017, 07:38:06 PM
I can but not sure how so some breadcrumbs would be much appreciated.

Jon

If you want to email me the PDFs I have software to reduce their file size.  Usually, anyway.

Thanks for the offer Ken. I just sent both files to your email address. Thanks for the help.

The PDF's are attached.

The first attachment is a Catalina factory cross section drawing of a toe rail dated 1980. The second attachment is a newer Catalina diagram I'm guessing from a sales brochure. The 1980 cross section shows plywood in the toe rail construction, the newer diagram does not show plywood. I haven't asked Warren when the plywood construction method changed yet.

FYI - Ken is creating a Factory Issued Drawings section in the Tect WIKI that will include these as well as other drawings.

The page is here:
http://c34.org/wikiwp/?rdp_we_resource=http%3A%2F%2Fc34.org%2Fwiki%2Findex.php%3Ftitle%3DManuals

Under the heading
Catalina Factory Issued Mods, Fixes, Construction Details, other documents

I added a single home for the CTY factory documents, just to make organizing/finding/updating them easier.  BUT, "feel free" if anyone wants to also add link(s) back to a document, on other wiki pages (for instance, under the HULL section for these two documents.)

Armed with those pics from the pdf's, I'll take another look at the toe rail with a mind to enlarging the skuppers.
