Technical question about Peeing

Some may remember the old RNLI report about the DOWF syndrome which they encountered now and then during rescue missions searching for yachtsmen. Apparently all too often the recovered body displays the characteristic of DOWF (dick out when found)

Is that the same as the US Coastguards OFS? Open Fly Syndrome?
 
The syphon effect can only occur when the liquid is enclosed within an air tight tube. In a porous tube, for example, the reduced pressure within the liquid column would draw in air and break the syphon as in the syphon break in the engine cooling system.

You would need to know the length of his tube to make a proper evaluation of this - or maybe not
 
On some boats I have been on recently, males have been asked to kneel down in front of the loo when having a pee (to avoid splashing the woodwork I suppose).

I find it a bit difficult to empty my bladder this way so need a return visit shortly afterwards. Therefore I have been thinking that there may be a technical reason for it.

Choosing my words carefully. When a male stands up to have a pee the longer unbroken stream must have a greater weight than when he kneels down and issues a shorter stream. Does this greater weight have a syphon type effect that drags out the pee more efficiently.

To extend the discussion. If that is true, then on a calm day, if a chap has a pee off a cliff, could the extra weight pull him off the cliff?

This is not a troll. I am genuinely interested in why the kneeling in front of the loo causes me a problem.

Male urethra relatively lengthly compared to that of a woman. Urine must go through prostate and penis before it is released. If man is not in a standing position urethra tends to get curled up so that urine does not flow easily.
A released stream of fluid is in freefall and has no tendency to pull on its source.
 
Very serious now! having just had my prostate "fried" by radiotherapy, I find it difficult to pee sitting down, apparantly to do with the fact that scar tissue affects the urethra. Standing up the tube falls naturally straight down from the bladder, thru the prostate and then down again to the exit. When you sit or kneel the urethra is bent and in my case makes it difficult to empty the bladder. I suspect a similar situation is happening here, bent urethra BUT also, is this signs of prostate trouble?, as I headed my previous post if you are of a certain age DONT DIE OF EMBARRASSMENT. If you are mid 50s on, go and see a GP!

I would just like to asure peoiple that not all prostrate problems are cancer. I have non cancer prostrate problems and have similar difficulties peeing, and I must admit that whilst sitting and kneeling are possible they are not the most comfortable or successful, so I would tend to avoid a kneeling or sitting only boat too.

The OP and any one else who has difficulties in some way with peeing should see their local quack ASAP. Life is a lot better since I got started on the pills.

True, true, very true.

I get a decent nights sleep again, and no more agonised searches for a public loo, or waiting in desparation at the local level crossing on the way home (3 minutes can be an incredibly long time!).

And no sign of anything malignant for me either, thank goodness.

But if you INSIST on males sitting down in your heads then I can NOT come sailing with you.
 
Congratulations Blue two, this must be one of the longest strings ever.
On my day Skip we were told to sit. When I first went out on my own boat and thought I couldn't be bothered to sit I smacked my head (forehead) on the light. Result, broken light and severe bruising. But I agree with others, you need to go again sooner. Is it because the wee beastie is squashed up in your trousers and possibly constricted further by a crotch strap?

Haha. Yes, I can confirm the Roger does have this in his heads. It made me laugh.

Thankfully, my hose is long enough to reach into the bowl when I'm stood up so.... :p

The weight of your pee is of no concern since it's a liquid, what you're probably doing, is bending over a bit as you kneel. Try keeping your back dead straight.

It's worth noting, well, it isn't but.. I often use a spare water bottle (destined for the bin, I might add) to pee in, but at sea, I'll go over the leeward side. In heavyish weather this requires kneeling down with the harness on, one hand clinging for dear life to a stanchion, and the other, well, anyway. Of course, I suppose it would be easier to just let the self draining cockpit take care of it :D
 
I keep a kiddies beach bucket handy to pee in (standing up in the heads or wherever depending on the sensitivities of the other souls on board). Then it can be carefully and non splashily disposed of down the loo, keel box, outboard well or wherever, depending as above.

The problem with using a container which you then empty is that we are not equipped with enough hands! OK in calm situation, but if at sea how do you hold container and aim :-) and hold on?

Sitting down - as enforced by SWMBO - solves this problem entirely. Once enthroned you have both hands free to hang on.

I appreciate that some older men with urinary problems may find sitting or kneeling to pee is difficult, but for most of us it is just a macho thing isn't it?

Apologies Stu,

I was generalising, I realise that some very young chaps also have waterworks troubles. :-;

Have you considered that maybe it's to do with the fact that the end of the "hose" :rolleyes: could be somewhat nearer the target for other folk?

But I can't say for sure as I have never considered closely watching guests / crew use the Toilet (eother onboard or ashore), and to be honest the fact that some people on this thread do clearly enjoy this activity and seem to also be recruiting others I find somewhat disturbing, even though I am fairly broadminded - and not terribly appropriate for a Forum open to a family audience.
 
I read this posting on a day when I've experienced the doctors finger up where the sun don't shine. All's well he thinks "but let's have a scan to make sure" was the outcome.

It also follows a week of sailing with 3 men on board. I do have a sensitive nose and yes the heads definatly had an unpleasant smell as I got down with bucket and cleaners to do the deed. It's when some jerk pees into a nearly full basin and splashes everywhere that it can look as if someones had a shower in there. Why can't people clean up after them or use what little nowse they were born with!!???

Thankfully, my boat does have a relatively high loo seat so standing for my little 5'9" is not too difficult and I have a little ledge in front where I can Kneel if in a sea. I can also still manage to pee sitting down on a good day but what a hassle it is to get all the gear off.
Having a tall loo seat does have other problems for me though. The physical position when seated is not 'squat' enough to do the business properly. Therefore a stretcher bar is to be designed to go accross from door to door which ideally i can make adjustable for those of long or short leg. This will also coincide with me dropping the heads sole in the winter to give better standing room. This will make the stretcher a vital part of the set up for those with challenged height.

Come to think of it good things can happen in the loo.
I usually read PBO and YM in the loo at home and it was there, that whilst reading Ellens first book, I made the decision that I had to buy my own boat, a Twister 28' of course! :-)

Many years ago I used to row. One of the highlights of our year was the Tideway Head of the River race. Nearly 400 racing eights, with most of them rowing gently from Putney to Mortlake, then turning round and racing back. But while we were waiting at Mortlake it was common for the crews to 'lighten ship'. Each cox carried a pint milk bottle and a towel. The bottle and towel were passed forward, with each oarsman in turn filling the bottle (sometimes several times) under cover of the towel, before again passing towel and bottle forward until it reached bow. Bow would then usually pass the towel back to the cox, but the bottle (glass, of course, no plastics in those days) was more commonly just dropped overboard.

If anyone should ever want a range of 1 pint milk bottles, I might suggest dredging just upstream from Mortlake Bridge. There must be thousands there.
In our school eight, it used to be standing only, odd numbers one side, even the other. Cox used to ensure the boat was stern to the wind to protect nimself. Balance was important!
 
seeing comment above......I have spent 45 years in the sport of rowing, as a coxwain, rower, and coach.

The most enlightening spell was when coaching a womans squad for three years ( well someone had to do it, and it was paid!) and finding out how they spent a penny when desperate before a Head of the River type race where you can be on the water for hours somedays, in a cold environment.
Those men who thought a bottle and a towel inconvenient may well ponder how difficult it was for the women!! :-)
