Connecting the Dots of a Rescue and Wreck

A series of Coast Guard search and rescues two weeks ago and a washed-up vessel now appear to be related. On January 21, the Coast Guard rescued three sailors from the 20-something-ft sailboat Pau Mua after it dismasted just outside the Golden Gate, knocking one sailor overboard. The rescue happened five days before the vessel washed up at Stinson Beach on Saturday, which we reported a week ago.

Following the January 21 rescue, the three sailors were taken back to the station for evaluation by EMS, Coast Guard spokesperson Brandyn Hill said, adding, “The vessel had no fittings, and without a mast there was no safe way to tow it. The projected path of the vessel was out to sea.”

Pictures taken of the Pau Mua by Coast Guard rescuers show its collapsed mast haphazardly lashed across the cabintop and a bright-white Johnson outboard motor serving as a rudder clamped to the stern. But there was no sign of the mast or outboard when Andy Spiegel and Katie Smith discovered the boat washed ashore a week later, although the cabin contents appeared largely intact.

GPS coordinates embedded in the Coast Guard images place the rescue location near Bonita Cove, a little less than one nautical mile due east of Point Bonita Lighthouse. At the time of the rescue, the vessel was drifting southwest, Hill said, but it eventually came to shore at Stinson Beach some eight nautical miles to the northwest.

Hill said the Coast Guard learned from San Francisco Police Department radio traffic on Channel 16 that the Pau Mua was in danger, but a police spokesperson was not able to confirm.

About an hour after the rescue, around 6:20 p.m., a photographer on land in San Francisco called 911 to report a sailboat appeared to be sinking approximately one mile offshore. Lt. Jonathan Baxter, a San Francisco Fire Department spokesperson, said they relayed the call to the Coast Guard.

“The ocean is too violent for our boats out there, so we depend on the Coast Guard for response that far out of the Bay,” Baxter said. “They did an extensive search using helicopters and boats and found nothing to lead them to a sinking vessel. We were canceled from shore.”

Hill said the Coast Guard — which was working without pay at the time of this incident because of the government shutdown — believes it is likely the 911 caller observed the Pau Mua adrift with no one aboard but conducted the search because they weren’t able to rule out the possibility of another vessel in distress.

That caller was Peter Kay.

“I was strolling along the Lands End trail, unable to ID this small white object mid-channel out of the Golden Gate,” Kay wrote us in an email. “It was triangular and stationary over quite a long time — I’ve hiked this trail for years and had never seen any object like that from afar. I found someone with a camera and a decent telephoto lens; he took a photo and enlarged it to reveal a mast with two white sails. At that point, after poor reception, I called 911 and asked for the Coast Guard. I finally was able to call in around 4:30 p.m., but was unsure if they understood me. I kept trying until they confirmed the location. They called me back 6:00 p.m. for more questions, SF Fire was at the Cliff House later trying to contact the Coast Guard, but they didn’t send out a helicopter until much later after dark.”

Even though the 911 call did not result in another rescue, Baxter did not want to discourage the public from calling if they see a boat in danger.

“Let us come out and see if it is an actual emergency or not,” he said. “And that’s exactly what this person did. They weren’t sure what they were seeing, but they firmly believed they were seeing a boat in distress, and they called it in. We would much rather take our resources out and confirm.”

On the same day as the Coast Guard rescue, a body was found at Ocean Beach in an unrelated incident.

Spindrift 2 Abandons Record Attempt

As we mentioned in Friday’s ‘Lectronic Latitude, Yann Guichard, the French skipper of the Swiss maxi-trimaran Spindrift 2, contacted his technical team ashore to report damage to the structure of the starboard rudder. Spindrift Racing was challenging for the Jules Verne Trophy, a nonstop round-the-world crewed record.

Later, in daylight, the team made a full assessment of the damage and possible repairs. Reluctantly, they concluded that they would be unable to make the necessary repairs without compromising the safety and performance of the 132-ft tri. “Because of this technical problem, we have no choice but to stop this record attempt. It is a huge disappointment to all of the crew. We are now heading to the southeast coast of Australia and expect to reach there in the next four days,” confirmed the 44-year-old Guichard.

“I share the heartbreak of #Spindrift 2’s crew,” tweeted team co-founder Dona Bertarelli, “especially after such a promising start. So proud of them taking on the world’s greatest challenges. Wishing them safe as they sail to Perth and counting the minutes until I see my husband [Yann] and son again.” The crew expect to arrive in Perth on Wednesday morning. Bertarelli’s 21-year-old son, Duncan Späth, is a helmsman and the youngest member of the 12-man crew.

Synthetic Standing Rigging. Why Not?

We want to re-rig our 30,000 lb. Kelly Peterson 46-ft sloop Esprit with synthetic — yes, plastic — standing rigging, but almost everyone we talk to (except ‘young sailors’ and ‘old sailors’ who have it already) are telling us not to! What gives?

There are many types of polymer-based rope in use today, most commonly they’re called Dyneema or Spectra. The two that are used mostly for standing rigging are: New England Ropes STS-HSR (Stronger Than Steel Heat Set Rope) and Hampidjan Dynice Dux. “In the end, Dux is like anything new. There is a distinct learning curve, and there will be skeptics and believers,” said John Franta, a rigging engineer with Colligo Marine

If you’re new to this concept, let me enlighten you.

A few of the reasons sailors are making the switch are: Anyone with a fid and access to some patience can rig their own boat; the rig is seriously lightened; it doesn’t rust, and you can keep a whole duplicate of the rig in your bilge; it’s two to five times stronger than the steel it replaced; and, did I mention, you can do it yourself without expensive and heavy equipment? Also, unlike a swage, the splices and thimbles are fully inspectable.

An article by the International Institute of Marine Surveying states, “The impressive tensile properties of these fibers make them ideal for standing rigging. [The technology] has allowed [Dyneema] rigging to be provided by smaller rigging companies or done by individuals as a DIY project.”

So, why wouldn’t you do it? Most commonly sailors cite that plastic rope stretches, chafes, and is susceptible to UV rays. All of these reasons can be addressed. For stretch, the heat-treated fibers in Dux and STS-HSR have had all the constructional elongation removed before it goes onto the spool. Some of it comes back when spliced for standing rigging, but that can be accounted for and taken back out by setting it with a winch.

“Actual working elasticity, at least if sized correctly, is less than that of 1×19 wire rope,” said Brion Toss, author of the Riggers Apprentice. I also spoke with a local Bay Area rigger, and he saw a 50% reduction in breaking strength over a 12-hour period when he stretched a 40-ft length of Dux to 30,000 lbs. I can’t imagine any chainplate staying attached to a hull when that much pressure is applied!

For chafing concerns, the rope can be dressed with chafe gear like — in this case — heat shrink tubing, by splicing on a Dyneema cover, or, if you’re really salty, one could serve and parcel the rope like we’ve done for thousands of years. For UV concerns, you could dress the whole rig like above, or, just keep an eye on it — as you should anyway. Just like all rope, there are visual signs of stress and age. “It is also much more resistant to UV damage than, say, Dacron or nylon.” Toss said. When chafe or UV becomes a problem, the line turns fuzzy. This is a warning sign to replace. Colligo Marine has charts of UV data for Dux. However, remember that Dyneema is two to five times stronger than the steel it replaced!

A local rigger agreed to help us make the switch, but said they were confident I’m someone who will have the wherewithal to do something about the maintenance. “For people unlike you, I would still tell them to use conventional materials,” they said.

Michael Moradzadeh, owner of the Santa Cruz 50 Oaxaca, has a Dux backstay. “I’d like to see how Dux stands up against heat-generated friction or a knife while under tension; if it lasts, I’m sold,” Moradzadeh said, adding, “Standing rigging is not something I’d like to have to learn in an emergency.”

One last question: Will my insurance drop me if I take the leap? That’s my biggest concern! “Lloyds of London have approved Dynice Dux for strength.” John Franta said.

So honestly, tell me why you wouldn’t do it? I’m still on the fence myself, but I have both feet headed in the direction of modernizing our rig. From my research, there are no documented disasters from this technology in the 12 years that this stuff has been in use.

What am I missing that I can’t find on the Internet or from the professionals I’ve asked?

Do It Yourself-ing
The problem is not severe. It can barely be called a problem at all. But if you're sitting down and helming on a long, slow run on my boat, you'll find that you have to hunch over — almost imperceptibly — to steer. You might even notice a little cramping creeping into your shoulders and back. The tiller seems as if it's just a little too low.
