Capsized My 26X

[Highlander]

I copied Rays mod but moved the the aft ports further aft about 3" same location same height as the bottom window stripe





same port inside these r 14' x 4" opening ports


but of course I went one further I added 10"x3" opening ports in th the head bottom window stripe




opposite side of the head



outside location



I also added rain shields so as I can just leave them open when it rains

PS sorry about the pic, quality as these r old pic,s I managed to retrieve from photo bucket

Russ,

My device that shows how far you are heeling stops at 45 degrees. I am a fortunate man who has a wife that is not fearful of extreme heeling. In the story I posted about asking her to close the ports, we were heeling far in excess of 45; way far beyond 45.

Yes, I am a prudent sailor, and the only thing I did wrong was be lax in my presail check list. The port was closed in time, and I don’t make a mistake twice.

You can see where my port side port is located.

Hi NiceAft!

Still think it’s cool you travel with a matching spare sailboat!

Ray,

Your portholes appear to be above the rubrail. This shouldn't be a problem. The capsized boat in the original post had portholes that were below the rubrail in the aft berth area (possibly well below-never saw the pics). The owner wrote

When you see the pics you can see that you do not have to heel severely to get those portholes underwater.

So, my comments, (and likely others' as well) don't apply to operable portholes in your location - i.e. above the rubrail. If you're getting water on those portholes, you're sailing in some pretty sporty stuff.

When the above was brought to the attention of Over Easy’s Admiral the demure response while not looking up from her reading was a simple “N#W…forget it”

So “sporty sailing” isn’t gonna happen within the operation procedures of Over Easy….at least not by design.

Well that would explain why they went over no ballast will cause the boat to flip over in big seas or high winds. Ballast tanks must be full.

I think ive read this thread now twice and it seems like a series of multiple unfortunate events that line up to cause a problem....ive heard this refered to as the "swiss cheese model" where 2 or 3 or more things have to be lined up for a bad outcome to actually occur. I will add a review of my galley & head sink thru-hull integrity to my winter checklist. Ive never really liked the fiberglassed drains on the 26x bc they dont have a valve and if one is installed the clamp force would be on thin tapered fiberglass. Maybe the best mod would be to totally replace the thru hulls. At least theyre above water.....tangiental reply but this thread popped up on homepage.

Hi Pitchpolehobie!

In Engineering Reliability Analysis there are several methodologies or approaches utilized.
In the Swiss Cheese graphical approach the "first contact plate" has all the potential things (components/operations) that could possibly go wrong for a device or system.
these are termed the potential Failure Modes (FM)

Within those potential things that could go wrong are specific singular aspects that would lead to a catastrophic failure of the device or system.
Those are termed Single Point Failure Modes (SPFM) and are generally clustered to a central region or 'bullseye' that are carried through all the remaining plates.

Then each of the remaining holes on the first plate are evaluated to determine if any of the other no-SPFM FM could in conjunction with any other FM would lead to a catastrophic failure of the device or system. Those are termed Secondary Combined Point Failure Modes (SCPFM). These are graphically arranged around the SPFM aspects.

Then if the device or system is valuable or critical enough the second process is again repeated for the non-SPFM or Non-SCPFM to determine if any three of the remaining FMs could potentially lead to a catastrophic failure of the device or system. These are termed Triple Combined Point Failure Modes (TCPFM).

Generally by that time one would have enough to start applying probability statistical valuations to each of the SPFM, SCPFM (& TCPFM if one has taken it that far).

Then starting with the FM items having the highest likelihood of occurring one would look into means to mitigate the issue by design, re-design, secondary system/device actuation, pending issue alarm, etc... One can also reduce the probability of occurrence by rigorous process control and device/component/system testing. Making sure that a device/component/system has sufficient margin to handle more than what it's intended operational requirements also minimizes the probability of occurrence. Its a rebalancing act to identify, evaluate and mitigate a device or system and Failure Mode mitigations within performance, cost and manufacturability constraints. one sees this every day in aviation, aerospace and other industries.

Where it comes to our boating community its generally not very rigorous unfortunately... especially when it comes to owner modifications.
Here it depends on the common sense of the individual making the modifications and the current/future operators of the vessel.
This is where design features like having a vessel with sufficient built-in flotation and the wearing of life jackets comes into play to mitigate the myriad of things that could potentially go wrong for a variety of reasons.
