[PSUBS-MAILIST] sea state

Emile,Maybe an inflatable CT extension could help.  You could use an inflatable raft with the bottom cut out.  Might be more trouble than it is worth, but an idea at least.Hank

Hi Alan,
I was looking forward to the video, but that's a pdf file! I would describe a K250 as a big hole in the water waiting to fill up whenever the hatch is open, but I agree Emile's boat is something entirely different. Also, in my experience there is a huge difference between boarding one person or two. If it's just me, I can time it better and slam the hatch right behind me, but if there's someone inside the sub before I get in, it slows down the move a lot and makes me a whole lot more worried about the consequence of a mishap. I can quite see a situation where a two person load would be too dangerous but a one person dive might still be accomplished.
Best,
Alec

Emile,we abandoned a dive in Snoopy 4 miles off the Florida Coast in what didn't seem like big seas.It looked too dangerous to board. Although With your sail it would have been OK.Next day we towed Snoopy out with Alec, Steve & 9 bags of ice for cooling.We had to transfer them to the boat after the dive, & it was a bit tricky. The sub sitsin the water like a rock while the support boat bounces up & down around it. So you are in danger of smashing your hull on to the sub. We had 3 of us trying tohold the boat off as we transferred crew.Here is the video that used to be on psubs. The first few seconds show the surface sea statewhich doesn't look too bad. http://www.ti.com.cn/cn/lit/ds/symlink/lm2593hv.pdfI would be interested in hearing how you get on.Cheers Alan

I've seen it flat as a parking lot. Not often, but it happens. You'll just have to make the determination when you get there. I hope it's a quiet day. And I wish I was going with you. It would be great fun to dive the North Sea again.Vance

Hi Vance,  The north sea is never flat.. A big offshore supplier will bring us to the spot. But they are not allowed to crane a sub with people inside so we have to go for the unsafe option.  But with the given (long?) wavelength 0,5 to 1 meter/ Emile Van: Personal_Submersibles [mailto:personal_submersibles-bounces at psubs.org] Namens via Personal_Submersibles

Subject: [PSUBS-MAILIST] sea stateHi All , or more those who operate a small sub on open sea. At what wind speed and wave height it is save to operate a small sub like mine ( freeboard outer sail 0,7 meter.)We plan to board the sub from a RIB For a possible Northsea expedition.. Best regards, Emile_______________________________________________
