transom question & source for transom bar

[bmcminn]

Why does the "wall" between the motor well and the cockpit have the cut-out shape? I think when I was at NMI they current designs do not have this. It would seem to me that in a really bad following sea that the cut-out would let water in that could be kept out.

Also, is the bar that goes across on some boats have called a transom bar? Anyone have a good source for one of these?

Thanks!

My theory on the splashwell cutout is that while it will allow more water into the boat when a wave comes over the stern, it will also allow more water to quickly evacuate when the wave subsides. If the wall was full height that water would have to slowly drain through the bilge pump, even on a CD25 because the scuppers would likely be below the water line.

If the hull with the more open splashwell does will not hold enough water to sink the boat and the hull with a full height splashwell does, then it would seem the short one is better. There would be more chance of a wave coming in, but less chance of a catastrophic swamping.

That is just my theory, though, and it has not been proven correct by internet memes, so take it for what it's worth. It makes me feel good on my CD25 when I see water getting into the splashwell and think how lucky I am that it didn't get all the way into the cockpit.

Interesting point about the water getting back out. Hmmm. In this video the guy talks about the trapezoid shaped stern and ability to empty water as being key in following seas, around 8:30. Not our boat but same concept on a smaller scale.

The transom "bar" is easy and cheap to make. You need a piece of SS tubing or pipe in 1" or 7/8". (Pipe is thicker wall) You also need two Bimini attachment pieces. These normally are screwed into the deck/gunnel to support the bottom of the Bimini.



You need a tube end:



Decide where you want the bar, measure the length of pipe you will need with these fittings included. Cut the pipe. And put it together.

We use a 1" pipe to support the Honda Generator over the well. It also holds several 2 gallon fuel cans handy and they will not tip over or "roam about".

Thanks, Bob. Where do I get ss pipe? Just google or is there Special Marine Stainless Steel that is even more expensive than regular ss.

Sorry, here's the link I was referring to in the earlier post. BTW, this is a seriously cool boat.

Again, around 8:30 he talks about stern shape effect on bow during following seas.

If this work you can see my "transom bar" here. If not click on the link and it should take you to my album for the view. I think this is a much stronger mounting than you can get with the bimini type attachment. Mine was made to hang 2 fairly large coolers on. One infront of the bar, over the cockpit, and the other one, smaller, that hangs in the splashwell.

Guess it won't show the pix, but should take you to it in the album.

Harvey, I used the Image Address, http://www.c-brats.com/albums/album606/IMGP1255.sized.jpg. It's a little different, then wrapped it with [img][/img].





So is that a solid piece that is custom made or order-able? Looks great.

Only time I've had water from wave action dump in the splashwell is when the boat is stopped. When moving the boat is fast enough even at "slow" speeds that waves don't enter the splashwell.

I have had several inches of water in the cockpit of my 22 while underway (forgot to put the drain plug in once). Pretty much filled the cockpit up to the sill of the cabin door and was deeper at the back. It was no big deal. The boat handled fine. It took a bit of work bailing (to help the bilge pump) to get all the water out.

Unless you get so much water on board that starts filling the main cabin, I doubt getting pooped a bit would be a problem. On the 22s with the new cabin style, there is no easy way to get water significant water out of the cabin other than bailing. Earlier boats had a bilge pump under the step at the cabin entrance.

My boat came with a fish cleaning table across this space and rotates down into the splash well. When I lower it down into the well it covers perhaps 90% of the opening. I usually keep it into the downward position when travelling as it closes up most of this opening and is out of the way. If I were to get a following wave into the splash well it would stop most of the water. The only time when I have had any water come into the splash well is when I have stopped too quickly and my wake followed me into the smash well, but never into the cockpit. I have since learned to slow down slower or turn out of the wake when I do slow down quickly.

Just a thought. I don't see why one couldn't design a rigid one-way flap that was hinged and hung from a transom bar. It would prevent water coming in, but would swing open to allow water to flow out.
