N30 #335 engine sea water strainer

[Bill M]

Hello again, this has to be the most helpful forum I have ever participated in and I have another question. I noticed the screws in the picture below while sanding and scraping (a lot of scraping!) the bottom of my boat and realized that there probably used to be a strainer there for engine sea water. I would like to replace the strainer with what was originally there so I can use the existing holes and am wondering if anyone knows what strainer was there?

Thanks again,

Strainers are a double edged sword. They help keep debris out of your intake but they also make it much harder to clear that debris once it gets in (and it will). Everyone has to make the decision for themselves based on their local conditions and the likelihood of various kinds of blockages. My personal decision has been no strainer. I like the idea of being able to pop the hose off and run a stick quickly down the through hull to clear it in a “crisis”.
Just something to consider....

In that vein, Bill, one must consider why (and for how long) that strainer has been removed. 

Paul's thought is a good one but, as he says, you need to consider where your boat is.

I would agree with Paul, exterior strainers will clog much faster than a thru hull and are harder to clean.  A plastic bag or balloon will stop the water flow outside of

 the hull, you need to enter the water to clear it, which if single handed or in any size sea can be dangerous.  They also are a breeding ground for barnacles, mussels and the like, again into the water with you.  Your interior strainer will do all the straining you need and easy to clear.  If you must put one on be sure it is of the hinged type giving access to the thru hull itself.  Good luck.

When I saw this photograph I completely forgot the initial question. 

My focus would be on those screws! Are they screwed into solid laminate or in the balsa core? Is there ANY chance of leakage, because that would be the end of this Nonsuch. 
Hinterhoeller did a great job making sure all thru hulls are through solid laminate but I question this one because it's different and larger.

In the cove where we keep BENEFIT the Speedo clogs with algae about mid season.

I would expect the same or worse would happen with a strainer.

We are at Mystic Shipyard, West Mystic, where are you working on your boat?

Next time you pull “speedo” / paddle wheel to clean algae etc- apply a light coat of waterproof grease 

Them creatures including mussels etc don’t like grease as fertilizer !!

I am going to go without the strainer, thanks for the quick answers. I don't know if the screws are into the core but I took a couple out today and they are well sealed. A little wet core isn't a huge endeavor but that is not an issue that I have. I don't know how long the strainer has been gone for but it is obvious that after it left someone removed the screws and applied sealer and then put them back in their holes. It is also obvious that one of the recent coats of paint did go around the strainernbut it doesn't look like the last coat did. This boat had a lot of bottom paint on it. The boat is at Safe Harbors Mystic right now but will be summering at Spicer's in Noank.

Thanks again for all of your help.

Thanks for the advice on greasing the speedo!

As I recall from pre-COVID strolls on the Spicer dock after dinner at the Sea Horse there were several Nonsuch in the slips.  We will look for you on FI sound.  

Did I see you are a Mudhead?

So you may already know about the Nonsuch racing contingent in our area.

I’ve been using a blue antifoul on my paddle wheel for some years but it rarely lasts more than three months before fouling and requiring pulling the sender with the predictable wet, messy result, drying and repainting. I usually ask my diver to spin the paddle after he replaces the zincs, but I failed to alert him in February because of the Covid distancing rules. Do you believe that waterproof grease would give longer protection?

Curt,

I am a Mudhead and last summer was the first time in 36 years I missed Wednesday nights or any racing for that matter. Raced a J/24 for years but for the past couple of years i've been racing on a Capo 30. There are a couple of Nonsuchs out there on Wednesday nights but what is really impressive is the Nonsuch fleet that races in off Soundings, the biggest class in the series.  I'm not sure that I'll be racing this boat except possibly Off Soundings.

The strainer was probably removed before the bottom was painted and someone forgot to put it back on. I have the same plastic strainer on my 30U and it does a good job. BTW the strainer plastic slots are flexible enough to slide a 1/2 pipe into the opening should you have to during the season. You don't have to remove it to clear any growth. I would recommend you replace it if it is on the head intake line. The strainer will do a good job of keeping large items from clogging the head intake. Especially items like  Jellyfish which since you are in Connecticut can be a problem in those waters during the summer.

[Joe Valinoti]

I agree that it’s better without the strainer, having experienced problems with trying to clear the intake during a delivery.  Had to dive on the bottom.  Also, those screws scare me as they could hang up on something.  I’d get rid of all that and glass it fair.
