Back to the topic at hand... As Bess and I have been "shopping" boats the past few months (with no REAL plan to buy), one thing we have noticed is the absence of what we consider "proper" scuppers. In other words, several big open holes that extend thru the hull from the side decks to outside the hull. What we are seeing a lot of are things that look like shower drains with grates over them that lead to... well... I am not really sure.

What I see as the main problem, as seems to maybe what happened above and DID happen to a friend is those "drains" get easily clogged with debris (leaves, dog hair, etc.) and the water has no place to go. In the case of a Tollycraft CPMY we saw last week, it would only take an inch or two of water to build up before it started to pour into the lower helm door. No good can come from that.

Tom-

PS... Hope the leg heals quickly.

Proper scuppers can be added to most vessels both during and after construction. At a cost of course. This issue plagues high end well designed (otherwise) vessels too.

Wood GBs have scuppers. These were carried over into the fiberglass boats and were used until at least 1975 if not later. Our boat, from the first batch of fiberglass GBs has scuppers and deck drains. Not sure why American Marine discontinued the use of scuppers on their Grand Banks line unless they added more than was worthwhile to the manufacturing costs or, more likely, they wanted a cleaner look to the hull.

Other than appearance (in some people's eyes) I can't think of any real downside to them.

Wouldn't mind two more scuppers in addition to the six already there.

Anybody have freeing ports on their boat? Seems like they'd do a better job than the meager scuppers many of us have (Coot excluded).

Scuppers, as can be seen on the right of pic, are generally excellent but they do take water in a beam sea - much to the annoyance of anyone sitting on the deck at the time....they get scuppered!

Does it rain that hard?

We have 2 in the stern. Sometimes I think they are there to let the big stuff over the side.

The only time the decks have been awash have been in beam seas. Freeing ports would be good.

No, but if a large wave fills behind the bulwark, I'll want the water to drain away fast.

In our neck of the woods they use mostly blocking ( 4 sets ) under the keel with the yacht slightly tilted to the stern.

Who are you putting that to Sailor....not me I presume, but higher up...? I can clearly see three keel blocks in my picture..

GRP resin will crush at about 4000PSI.

I wonder how heavy this boat is and how many SQ inches of boat is in contact with those few blocks?

I was revering to Andy G's set up in the first picture. The close up post doesn't look as bad. I would still rather have keel blocks than poppits under the keel. Poppits are fine for outside of the keel area.

Right. Yes...no real argument there from me...I like solid wooden blocks, every time.

I like Bendits aft control station. Very useful and seldom seen on pleasure vessels, more common in Chesapeake Bay.

Freeing ports good. Hard to do on a canoe stern.

Here's a pic of the 2 we have on the stern.

Provided you don`t mind the risk of toppling,you get to antifoul those parts of the keel often blocked for quite some length which miss getting antifouled.
Fact is,she did not topple, nor did the other boats on the hard, so the system works, but the loads on the keel must be uneven. Even so,we saw her while up,and were not alarmed at the support system. BruceK

The yards we use all lift the boat in the Travelift after the bottom's been painted so the spots where the keel blocks and stand pads were can be painted.

Well Bruce you certainly trusted the support system enough to climb up for a cold beer. The only thing that toppled was poor old Was, still he's on the mend, up and about in a couple of months.

The scuppers are a genuine issue though, the water that pooled amidships was caused by the design of the deck, I had not realised the bow and stern were so much higher than amidships, there really should be some scuppers just aft on the starboard and port sliding doors.The after scuppers were not blocked in any way , the water was still 6' from the actual drainage point, luckily we have high sills for the side doors.

Thinking about it though, this is really only a problem when the boat is on the hard, she drains quite well when on the water.
