You guys did a magnificent job. This was the<br>> best sub trip of my life!<br>><br>> I spend the day organizing the video and pictures from the trip and mailed<br>> them to Alec who has graciously agree to edit into a video of the 2017<br>> Psub Regatta.<br>><br>> I still need to review the data I logged from the trips but the key points<br>> were the first ocean side dive was to the coral heads which is 3.9 miles<br>> from Doug's house so 7.8 miles total tow with average cabin temp of 93F and<br>> RH of 80%. Average speed was about 4.5 MPH. As long as we ran partially<br>> submerged to was hot but fine. This was a test dive to see if we could get<br>> out deeper. Water was not clear at this location. The deeper dive on Aug<br>> 3rd was out to the edge of the deep water. The 7.8 miles from Doug's house<br>> (bay side) to the dive site was smooth and we ran submerged so even thought<br>> the cabin temp and RH were high, it was not bad at all as it was a smooth<br>> tow and there were thinks to see on way out. At the second dive site the<br>> water was 100 ft deep and very clear with 4-6 ft swells. Could see<br>> the sub on the bottom from the Boston Whaler. The tow back was rough.<br>> With 4-6 ft following seas, it was like being on a roller coaster both in<br>> the boat and in the sub. Second dive had a total of 15.6 miles of towing at<br>> 4.5 MPH, 94F and 84% RH and hatch closed time of around 5 hours. I did not<br>> loose my cookies but it was close.<br>><br>> As Doug noted, the consensus of all was that we need a tender vessel with<br>> launch capability to get the subs out to the dive sites without towing.<br>> Towing subs sucks. All survived but I used up all my on board water and<br>> upon making it back to the beach, consumed several gallon of water. We<br>> were all pretty whipped.

I know that between Dan Lance and Cliff, I learned more<br>>> than I can remember last week.<br>>><br>>> Mike Patterson, mom, dad and myself were all just providing whatever<br>>> kind of "troop support" we could to Cliff and the R-300.<br>>><br>>> River, Steve and Myself got in some dive time on Snoopy in the canal<br>>> (which was great), but I think the biggest accomplishment was getting<br>>> the R-300 out a ways into the ocean.<br>>><br>>> Our Boston Whaler (a 25' boat with a single 250hp Yamaha) was able to<br>>> tow the R-300 out about 5 miles into the ocean (at about 4mph). We<br>>> were in radio communication with Cliff most of the time, though we did<br>>> suffer a few intermittent losses in comms. When we got to a spot about<br>>> 100 feet deep, we started to slow down a bit and at that point the tow<br>>> line hook (an admittedly cheap thing) let loose(!) so we decided that<br>>> we had reached our dive location. We switched from marine radio to OTS<br>>> and Cliff started down. Visibility was supurb! As Cliff neared the<br>>> bottom at 100 ? 110 feet, he was still quite visible from the Whaler!<br>>> His 18 foot long R-300 looked to be about 3 inches long, but wow did<br>>> it ever stand out from the rest of the sandy bottom. Cliff spent about<br>>> an hour "flying" his sub, surfacing, diving and maneuvering about,<br>>> testing systems and observing the ocean around him. By the time Cliff<br>>> surfaced and we towed back to port Antigua, elapsed time stood at 4.5<br>>> / 5 hours (estimate). Cliff said that he stayed cool by the water<br>>> flowing over the sub's dome hatch while in tow. Upon returning I think<br>>> we were all ready to take a break, but everyone felt great<br>>> accomplishment with the mission.<br>>><br>>> A couple of lessons I took away from the tow out: We need better tow<br>>> equipment (better line, hardware and maybe a quick release). Our boat<br>>> REALLY needs a GPS (still don't have one). Towing into waves isn't so<br>>> much a problem, but when towing with the waves, our tow line needs to<br>>> be measured so as to sustain the proper distance between tow vessel<br>>> and sub (otherwise the sub and boat are constantly slacking and then<br>>> jerking, stressing the tow line and making it difficult for boat and<br>>> sub to track straight).<br>>><br>>> The devotion of our crew was amazing, even in the heat and the waves<br>>> everyone did their jobs. Managing even a small sub operation like this<br>>> is more work / effort than meets the eye, that's for sure. At dinner,<br>>> one of the main discussions revolved around a support vessel that can<br>>> carry a sub or two on board, eliminating the slow, time consuming tow<br>>> out to an ocean dive site. Dan Lance shared details on his support<br>>> vessel project, which is no doubt going to be a dream in terms of<br>>> logistics. Hopefully when said vessel is ready to sail, Dan will lend<br>>> its services to host a diving event! ~ Douglas S.<br>>><br>>> _______________________________________________<br>>> Personal_Submersibles mailing list<br>>> Personal_Submersibles@psubs.org<br>>> http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles<br>>><br>><br>><br>-------------- next part --------------<br>An HTML attachment was scrubbed...<br>URL: <http://www.whoweb.com/pipermail/personal_submersibles/attachments/20170824/8ba9ee48/attachment.html><br><br>------------------------------<br><br>Subject: Digest Footer<br><br>_______________________________________________<br>Personal_Submersibles mailing list<br>Personal_Submersibles@psubs.org<br>http://www.whoweb.com/mailman/listinfo.cgi/personal_submersibles<br><br><br>------------------------------<br><br>End of Personal_Submersibles Digest, Vol 50, Issue 91<br>*****************************************************<br></body></html>
