195CC cockpit drainage experiences?

[rscott]

I have to agree. I have a 135 HP four stroke on my 195cc, and keep the boat moored at a dock. Although it does drain a bit slow when I wash it down, I never really have standing water in the boat. I also do not have a T-top, so that may add to the boat riding a little higher in the water also.

My 195CC with a 140 on the back doesn't angle towards the stern enough. I keep it on the dock and have to stand on the stern after i wash it down. I see it as a design flaw - boats should angle to drain to the scuppers. It's the only major issue I have and it drains fine when I'm running the boat.

Since starting this thread in 2006, I've had a couple seasons under my belt with this issue. So I can now lend some observations to this discussion.

You are quite right about the scuppers. Note that water flow is produced by a head of water. In this case standing water that is only about 2 or 3 inches, the distance between the deck surface and the water level inside the stern drains (the same as outside the hull).

On the other hand, during a storm and bad seas, while underway, these drains are superb, since they use the Venturi action of water flowing past the scuppers to quickly drain the cockpit. They also have as a backup, check valve floats that prevent water from entering the cockpit in following seas through the scuppers. Quite frankly, these drains were not designed to carry away washdown water, and most deck water, while not underway, drains into the bilge through the deck/hull seams, which without an extra midships drain can take a long time. It's a design comprimise that is the result of the fact that there is no transom plate with deck-level scuppers as with my previous boat.

I only have a little Merc 115 Optimax, and a T-top. As my original post documented, I had standing rain-storm water, either at mooring or at my dock. I demonstrated to Triumph regional sales (who graciously came down to my dock) that by pouring a 5-gallon pail of water (I threw in a bottle of green vegatable dye) at the stern, the water migrated forward and sat somewhere around midships. With careful measurments, he concluded that the aft deck plates were indeed higher. He communicaated by cell phone on the spot with the Triumph engineers, who didn't believe him. So he sent them little movies from his digital camera, and in the fall of 2006 they took the boat back to NC conducted some tests and returned the boat with a midships drain between the console and seat pedistal.

After a complete season, I can report that I have little problem with standing water after a rainstorm, but the midships drain does not aid in a deck wash-down, since there is just too much volume. So here is what I do.
1) Take out the check valve balls in the rear drains by unscrewing the grates using a fuel cap wrench.
2) Open the forward deck hatch lid
3) Get as much dirt out using either the washdown hose or a garden hose while standing on the stern
4) Use the hose to flush out the seams along between the deck and hull.
5) Stand on the bow while flooding the deck from that position, and shifting your position from side to side while waiting for the water to flow into the opening. Wash water will flow directly into your bilge and be pumped out by the bige pump.
6) Close the forward hatch lid
7) Replace the check valve balls and install the grates.

Hope this helps others with this problem.

This really is my only complaint with this boat, but given heavy-seas cockput drainage performance, I'm willing to live with it ... literally.

Boats.

We love them and we (talking about myself) do complain now and then. A long time ago, and after many years of searching, we finally reached the conclusion that there was no such thing as the “Perfect Boat”. Our 210CC is as close as we found to perfect and still we continue to make changes (what I call enhancements).

Glad you solved your problems, at least where you can live with it.

I have a 2007 195CC. My deal tells me there is a factory recall for the self bailing drain valve. Apparently, they are replacing the current ball valve with something called a duck bill. Not certain this is the same issue, but I believe it is.
