What needs to be addressed is the Wetsuit/harness/got to piss scenario.

Man I've been seen running full speed from my beached boat to the woods whilst shedding layers many times.

Yeah, but men are not known for their modesty.

I feel dirty, I pissed in the woods right in front of the park ranger once.

He didn't like that to much

If this is truly a problem, try a pilots (airplane) shop. There you should be able to find a pilots relief tube. Depending on the manhood of the pilot they come in different sizes. I think they also make a female version that sort of resembles a narrow oxygen mask with a long tube. Of course she would have no more modesty after use.

Wow. You mean I can run the tube out the latex ankle seal of my drysuit? Cool!

Pleeeeease. I thought it was a joke too. Hope nobody took my solution seriously...

Sounds like someone is looking for a 2nd house tax right off.

Of course everyone knows that the modest cruiser carries a poncho for people who want to be discreet. You can always claim that it is emergency gear. I saw a neat porta potty at www.thepett.com

Judging by that statement, you are seeking an entire portapotty/outhouse that has four walls and a doorway. But if you are willing to stay on one side of trampoline while the women are on the opposite side, you might want to try the method shown here.

Mary, that little device you speak of can be found at www.Campmor.com.

Actually Mary, we saw those devices in the kayak store that's just South of your house.
Jack & Brenda

AH, a true poop chute.

If these women have any sense of modesty, they will not allow him to post pictures...

Jonathan

Don't worry, Jonathan; I think he was talking about pictures of the device, not of the users.

Whats modesty?!

A while back a guy was advertising a throne with a bag under. He was a hunter and he needed a place to go. His design had a reese hitch bar attached to the throne. This slipped into the reciever on his truck. He called it (you may have guessed by now) ...The Bumper Dumper. Perhaps something that attaches to the rear beam so you can dangle your feet while....you know.
