New Boat 4 Sled

A good memory is vital to woodworkers, especially wooden boat builders. All that beautiful wood, the grain, the colors, and - yes - the smell, disappears under multiple coats of protective paint seldom to be seen again. As I watched "FREDA's" rebirth at Spaulding's Boat Works in Sausalito over the years, I savored every rib and plank as it was lovingly shaped, steamed, fastened or hung until a beautiful piece of wooden sculpture stood proudly in the shed. Then one day when I visited I saw a white boat sitting there. All those thousands of wood working hours disappeared under the protective paint, only to be seen in another hundred years when a new generation of dedicated wooden boat builders with hopefully dismantle this century's work and do it all over again.

That's a beautiful piece of wood and will be a great rudder to safely steer you through those San Juan islands shoals and rocks.
 
Celebrate Earth Day!

Each year, Earth Day—April 22—marks the anniversary of the birth of the modern environmental movement in 1970.

The height of counterculture in the United States, 1970 brought the death of Jimi Hendrix, the last Beatles album, and Simon & Garfunkel’s “Bridge Over Troubled Water.” War raged in Vietnam and students nationwide overwhelmingly opposed it.

At the time, Americans were running leaded gas in massive V8 sedans. Industry belched smoke and sludge with little fear of legal consequences or bad press. Air pollution was commonly accepted as the smell of prosperity. Our school classes in the LA Basin were regularly kept indoors because of the pain of breathing eye stinging smog.

Although mainstream America largely remained oblivious to environmental concerns, the stage had been set for change by the publication of Rachel Carson’s New York Times bestseller Silent Spring in 1962. The book represented a watershed moment, selling more than 500,000 copies in 24 countries, and began to raise public awareness and concern for living organisms, the environment, and links between pollution and public health.

After witnessing the ravages of the massive 1969 oil spill off Santa Barbara, Earth Day 1970 was imagined, planned, and promoted by classmate and student body president Denis Hayes to give voice to an emerging environmental consciousness by channeling the energy of the anti-war protest movement to put environmental concerns on the front page.

Denis Hayes, with the support of Senator Gaylord Nelson of Wisconsin and then Republican Congressman Pete McCloskey of California, built a national staff of 85 to promote events across the land. April 22, falling between Spring Break and Final Exams, was selected as the date of the first Earth Day.

On April 22,1970, 20 million Americans took to the streets, parks, and auditoriums to demonstrate for a healthy, sustainable environment in massive coast-to-coast rallies. Thousands of colleges and universities organized protests against the deterioration of the environment. Groups that had been fighting against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, the loss of wilderness, and the extinction of wildlife suddenly realized they shared common values.

Earth Day 1970 achieved a rare political alignment, enlisting support from Republicans and Democrats, rich and poor, city folk and farmers, tycoons and labor leaders. By the end of that year, the first Earth Day had led to the creation of the United States Environmental Protection Agency and passage of the Clean Air, Clean Water, and Endangered Species Acts.

As 1990 approached, a group of environmental leaders asked Denis Hayes to organize another big campaign. This time, Earth Day went global, mobilizing 200 million people in 141 countries and lifting environmental issues onto the world stage. Earth Day 1990 gave a huge boost to recycling efforts worldwide and helped pave the way for the 1992 United Nations Earth Summit in Rio de Janeiro.

As the millennium approached, Denis Hayes spearheaded yet another campaign, this time focused on global warming and a push for clean energy. With 5,000 environmental groups in a record 184 countries reaching out to hundreds of millions of people, Earth Day 2000 combined the big-picture feistiness of the first Earth Day with the international grassroots activism of Earth Day 1990.

Earth Day 2000 used the power of the Internet to organize activists. Hundreds of thousands of people gathered on the National Mall in Washington, DC for a First Amendment Rally. Earth Day 2000 sent world leaders the loud and clear message that citizens around the world wanted quick and decisive action on global warming and clean energy.

Much like the early days of 1970, Earth Day 2016 comes at a time of great challenge for the environmental community. Climate change deniers, well-funded oil lobbyists, reticent politicians, a distracted public, and a divided environmental community all contribute to a narrative of cynicism versus activism. Despite these challenges, Earth Day has prevailed and remains a relevant, powerful focal point, celebrated by more than a billion people in 192 countries, the largest secular observance in the world.

The fight for a clean environment continues with increasing urgency, as the effects of climate change and pollution become more manifest every day. As sailors skilled at turning the wind into forward motion, and who regularly see the effect of pollution on the health of the world's seas, we have a responsibility to educate, whenever possible, the desirability of leaving a clean wake.

WILDFLOWER's new rudder has its final shaping complete and checked with templates. Next up is a protective sheath of 4 oz. S glass fiberglass cloth. overlapped at the leading edge. The fiberglass cloth is not for strength, rather abrasion resistance, and to keep the finish materials from cracking, and letting moisture into the wood.
Rudder4.jpg

Howard says 4 oz.S glass cloth is as strong as 6 oz. E glass and 80% strong as carbon fiber.

The finish coat on the S glass will be West System #103 epoxy resin with #207 clear hardener, applied with a reusable black bristle brush, making for a clear and glossy finish. (We don't use foam rollers as they force bubbles into the goo. Likewise, we don't use disposable brushes as they tend to shed, no bueno on wood that will be finished bright.) It's the #207 clear hardener that makes the rudder finish glossy, clear, and smooth.

Lastly, several coats of varnish will be added for UV protection, and the leading edge will be painted white to show weed. Also, we will build a sheave box at the top of the rudder for the kick-up adjustment line, as well as the attachment point for the pneumatic cylinder that assists in kicking up the rudder when pulled by hand, or when it hits a submerged object, like the bottom on a beach landing.

If you are wondering why a single rudder on a catamaran, it is because the single rudder is on centerline. No, we don't fly a-hull except by accident.

The breeze fan along the CA coast is currently on "High" setting, with gale warnings for NW winds from Oregon/CA border all the way to Mexico. In the last 24 hours gusts of 40 plus knots have been recorded at weather buoys offshore Bodega Bay, Half Moon Bay, Monterey Bay, Santa Maria, and Santa Rosa Island.

Similar conditions will continue today, as a strong high pressure, 1031 mb., is anchored off the coast. Conditions will moderate later in the week, 20-25 knots through Friday. But currently not a good window to be bashing north in anything less than a 40,000 hp container ship.

It's why the lighthouse keepers at Pt. Sur used to keep their children and chickens on leashes. As the good sail doctor would say: "Sheep's in the meadow." "Bolt your socks on, take two reds, and call me in the morning."

Though I am well aware that Rocky Mountain Elk jerky is particularly favored by some SHTP buglighters for its nutritional and tasty qualities, I was unprepared for an "unclear on the concept" encounter yesterday at our local West Marine.

I'd briefly visited the store to retrieve some free sailing magazines, usually stacked on shelves between the footwear and bungee cord. I guess I was too late in the month to find Lat-38, 48 North, or Pacific NW Yachting.

The only printed matter available was a glossy 2016 California Big Game Hunting published by the California Department of Fish and Wildlife.

IMGP0001-011.JPG

A West Marine sales person approached and asked if he could help me find something. I said, pointing to page 46 in the Big Game Hunting magazine,
" these hunters on page 46 look happy with their magnificent deceased wild animal. What aisle has guns and ammo so I can get in on the action?"

The store went silent... The sales rep rolled his eyes... Ammunition in West Marine?

The good news is, to protect endangered California condors from lead poisoning, hunters cannot use lead bullets in condor habitat.

Howard assures me we will not be putting small bumps, "tubercles," on the edges of WILDFLOWER's new rudder.

tubercle.jpg


Says Howard: "Tubercles are found on humpback whale pectorals. Humpbacks weigh many tons and don't swim much faster than 5 knots."

humpback tubercles.jpg Pec.jpg

Paul Bieker is designing foils (rudder and daggerboards) with tubercles. His foils are being tested on ORACLE's AC catamarans. Reportedly, Paul's tubercles act as vortex generators and work to delay rudder stalling caused by cavitation, especially at high speed. The tubercles are said to divert air flowing downward on the rudder's surface that causes lack of control at high angles of heel.

Nice looking rudder! How do you come up with the templates for the shape? I am making a new kick-up rudder for my Jester dinghy.

Fender covers actually a pretty good deal for keeping dock grease, grime, and mildew off the fenders and topsides. Mine get tossed in the laundry every so often. When worn out, they're tossed in the ragbag. Replacements are < $3.00 a pair at the Thrift Shop for a pair of sweat pants. Cut the legs off to the right length, slip the legs over the fenders, and Bob's your uncle.

Don't tell Patagonia.

Robert,
Howard built his kick up Jester rudder for Jester #8, which was built in 1967. Here's Howard's description:

I used a NACA 0009 foil shape. The max. thickness is 30% aft from the nose, and the thickness is multiplied by 0.09 times the distance from the nose to the trailing edge.

The tiller is cross linked to the rudder head so when the tiller is raised it lifts the blade.


Being able to sail through the kelp beds with the rudder kicked up helped Howard win that most prestigious of Jester races, from SC Harbor, 4 miles to China Beach, just east of Capitola.

A toast to Hans Vielhauer, veteran of the first two SHTP's on the Scampi 30 MACH SCHNELL, then two more SHTP's on his Cal-40 CHAPARRAL, as well as a circumnavigation.

Hans was tough as nails, an excellent sailor, calm, confident, and in tune with the ocean. Hans was also quite shy. He told me this story, not bragging, but as matter of fact. It was later confirmed by video and by his close friend and crew Marianne Wheeler, who wrote the following tale for Latitude 38:

"On June 13, '95, Sonoma's Hans Vielhauer and his Cal 40 Chaparral were caught in the entrance channel of the Ala Wai Boat Harbor by the 'great southwest swell of '95'. This was the swell that caused lots of damage and killed several surfers in the islands. According to Honolulu newspapers, the swells were the biggest to hit the south shore in 15 years. Hans and Chaparral were motoring in the channel when a towering wave broke across the entire opening, ripping the signs off the channel markers and pounding the shore. Chaparral was knocked down by the breaking wave, and Hans was washed overboard. As he went over, the heel of his foot kicked the gearshift into reverse. When the breaking wave passed, Chaparral righted herself, and made a nice circle in reverse — right back at Hans! When he surfaced and saw his boat coming back toward him, he knew there was only one thing to do — get back aboard! Although well past the age of 60 at the time, Hans managed to climb aboard his Cal 40, after which he put the transmission in forward and set a course for deeper water!"

Go, Hans.

What a fascinating story. I mentioned to someone a few days ago after I declined their back up dive computer when I changed the battery in mine (it's not easy and could have cost me a dive in a remote area if it had leaked) that I'd rather be lucky than good. It seems certain that Hans was both.

Also, from your previous post about Howard's nifty rudder design. I thought I'd show you my rudder post when I dropped it recently. There's not much I can do to get through kelp beds with it, but it's beefy, ain't it? An older J-boat pulled out across from me and his was similar though it had a bearing on the ring that was a bear for the yard to remove. Mine is just chocked full of grease with 4 zerc fittings that I had no idea about till now. It's always good to know how your boat works...

What is that rudder post made of? Looks like redwood slathered in lanolin.

It does look "drippy" doesn't it? No one could really tell what it's made of, but the consensus is that it probably has a metal core that has fiberglass tapered to fit the large end. Not sure why they would make it club-footed like that. Other guesses are certainly welcome! Do you think I can get a waiver on the emergency rudder requirement because it's such a beefy rudder? If this thing were to go, it would probably take my stern with it and negate the need for an e-rudd.
 
Hi KYNNTANA,
Hard to say what the rudder shaft construction is without cutting into it. And you are not going to do that!

Zerk fittings are nifty for rudder posts. On the Cal-40 we had several Zerks, and just kept pumping in grease, once a day, all the way to Hono. Not a squeak or clunk to be heard, and no friction either. (This was before carbon shafts and hi-tech rudder bearings.)

I don't know if you did this while hauled out. But it can be a good idea on older rudders to drill a small drain hole, 1/16" is fine, and see how much, if any, water drains out.

When the rudder proves dry, or stops draining, you can easily re-plug the little drain hole with Marinetex, Bondo, or chewing gum. I drilled and tapped my rudder drain hole for a #8/32 SS machine screw, which was screwed in place with silicone sealant. On haulouts it was an easy matter to unscrew the drain plug and check the rudder guts for rusty brown water, never a popular thing to find should there be weldments in the interior framework fabrication.

Out of sight, out of mind. Has anyone had a rudder x-rayed?

Thanks Skip, that was just the info that I needed. I have found several websites that describe NACA 0009 in detail. I sailed that Jester race in the early '80s and was envious of those that had kick-up rudders and were able to sail through the kelp bed. I had to take the outside route and finished second to last, just missing being awarded the Jester hat. My rudder will not be as fancy as Howards as I am not racing and don't really need the tiller activation feature.

Well, sorta, if you count ultrasound... fat lot of good that did me in the end!

OTOH, maybe an X-ray would have told me more about the construction errors, maybe not.
probably would have given a clearer outline of the metal work.

Apologies; the above is a little off topic. You're speaking of water in the rudder and corrosion, not shoddy engineering of the armature.
