moving scupper through hulls to above waterline

I have an 1976 E27 with helm steering that has 4 scuppers (2 in each cockpit). The scuppers drain below the waterline in what looks like 1 1/2 or 1 1/4 through hulls located either side of the companionway one in the quarter birth starboard and one under the sink to port. In the past few years I've changed all through valves to ball valves. the sink also drains into the same line on the port side.

In spring, when it gets warm enough, I am planning on taking out the transponder and speed wheel located on each side of the bilge and glassing those holes. I installed an in-hull transponder unit under the V berth and no longer need these through hulls. (speed I just use GPS)

Since I will be grinding and glassing those holes I have been thinking of moving the two scupper through hulls to the stern of the boat where they would exit just above the water line, where the hull sweeps up, instead of below it. I know one or the other may be under the waterline when sailing but when at dock they would be a few inches just above the line.

My questions are:
Has any one ever moved these through hulls and

Is there any reason not to locate them just above the waterline

Thanks in advance

I can only say that through-hulls don't bother me such that I would bother relocating the drains. Also, I left my old paddlewheel and obsolete transducer in place--they don't bother me either.

If the thru hulls / seacocks are good quality, operated periodically to ensure they function smoothly, and checked for corrosion, I also wouldn't worry about them. Although I close most of our seacocks when off the boat, I leave the ones for the cockpit scuppers open all the time to ensure good drainage, but I still operate them periodically to ensure they don't get stiff.
But if you enjoy working on your boat and are good at fibreglass work, go for it! :)

Remove them! A PO did it on Cinderella and I’m so glad he did. The fewer holes below the waterline the better. My cockpit has two large drain pipes above the waterline at the stern that all 4 cockpit scuppers feed into. The scuppers 90 just below the cockpit sole and head straight aft. There is a T either side of the aft cockpit well, where the aft scuppers join them.

If I was you, I’d consider an easier approach. Just glass two 2” pipes at the level of the cockpit floor directly through the transom and out the stern. I may do something similar if I ever get around to cutting out that annoying T in the e-35 cockpit.

A PO removed the wheel and did a great job installing a much beefier rudder/tiller. I am so glad he did, these boats are a dream to tiller steer. Why they ever put a wheel on them, and all the way in the back where the skipper is most exposed to the elements is beyond me. Wheel steering is a sure way to overcomplicate the small yacht and open one’s self up to more steering failures.

We have filled our cockpit several times broad reaching in big seas in 30ish kts. The cockpit takes quite a while to drain. At least a minute. The kiwis have it right, open the transom and that water disappears just as quickly as it fills.

I like the idea.
Just remember to have some flex tube between the cockpit and transom, as the inner and outer parts of the boat do move in relation to each other.

I have an E35-2 and really (really !) do not like the drain though the bottom of he boat. Especially in winter.
Is there enough drop to get from the fwd cockpit drains to the transom? Or do you exit though the overhang ?

It's not only the holes in the bottom of the boat, having a much bigger set of drains out the stern would lessen the continual need to clear the small diameter drains. The convoluted hoses love to hold onto this junk.

They exit through the overhang. I’ll try and get some photos next time I’m at the boat

pics would be great. The only reason I haven't had this done is not sure where to put the drain hole.
Going to get it done next season. thanks.

I like above the cockpit drains, reminds me of sport fishers and commercial vessels =) and its KISS

My e25 has this type of setup using a single drain hole on centerline located (what I estimate) 6” or more above waterline. Inside the cockpit there is a molded-in sump so water doesn’t pool anywhere (it also holds the mast crutch in place nicely when the boat is sitting on trailer). Pretty well thought out IMO.

downside? On a heel it won’t drain water??

Thank you all for the advice. In spring I will for sure glass over the two unused sending units only because I also am of the "lesser holes is better camp". I may wait a year but will still consider moving the scupper through hulls because You really can't shut these when leaving the boat and I am always concerned, not with the through hull itself, but the hoses, clamps, etc. that accompany them. Also, I really liked the picture, in one of the other posts, that shows the stern upsweep of a E38 I think, with a neat row of through hulls just above the water line. Thanks again and all have a merry Christmas or Holiday. TPCorrigan

You are not kidding. I use the same expensive tool you use and ever that doesn't clear out all of it. while on the hard here in the winter I have run an air hose into the boat and blasted the stuff out the top. Always fun. Thanks

How will you drain your sink?
Same way as now with a "T" just would move the actual exit from under the locker/sink to back a few feet. the only down side I could envision is the actually through hull would be technically a few inches higher in the boat but certainly low enough for the sink. Good thought though. Thanks
