(Odin you know who I am talkin’ about) Guinness Book really should look into that one and not just ones they pick and choose who meet there public relation criteria.

Comment on 'A massive hurdle' by Spike Selig http://www.xssailing.com/article/a-massive-hurdle/#comment-54205 Wed, 03 Jun 2015 20:11:46 +0000 http://www.xssailing.com/?p=21509#comment-54205 This boat is healed over. The bow is in the water (almost) and the starboard stern is in the water. The waterline is thus angles from the bow at centerline to the stern (1/2 the width of the boat outboard from the centerline). The boat is, because of its maximum width carried to the transom, its flat aft sections and its extreme beam never sailing on a waterline lined up with the centerline of the boat when the boat is healed.
This induced distorted waterline when sailed healed over causes an induced leeward helm, causes the angled water flow to flow over the now “hump” of the U shaped front end, and causes the waves to pound into the leeward front end of the boat splashing over the boat. No water is sliding rearward down the windward side of the boat as that side is out of the water. The small hull volume up front also makes the boat bore through waves rather than rise up over them, a situation that results in drenching the crew in higher seas and winds.
If the boat should capsize the mast would hit the water after the boat is 90 degrees healed meaning the buoyant lift is far off to windward, the boats center of mass is to leeward of this buoyancy and thus the hulls weight moment is driving the mast under. if the keels weight is missing (broken off keel) or a wave heals the boat past the point of no return, the boat goes turtle.

I suggest that to get around the need for these boats being designed with wide transoms for plaining, the designer build a narrower boat with two keels and two rudders, these placed on the sides of the boat outboard of the maximum width, these appendages hanging on a protruding pivot keel bolt, with appendages to allow the rudders to hang outboard of the hulls maximum width. The leeward keels and rudders could be on pivoting mechanisms that allow the leeward keel and rudder to swing in and out at the bottom so that the vectors of these two leeward appendages can be angles more upward, When the keel and rudder are cocked inward enough, their vectors will actually pass over the center of heal and help keep the boat from healing.
The Windward keel and rudder can be cocked outward at the bottom so that as the boat heals, they come clear of the water, increasing their weight by the loss of water displaced and, with their weight decreased buoyancy help resist healing. As the leeward keel and rudder are always in the water, their buoyancy will. being to leeward of the healing centerline, help keep the boat from healing.

Moving the keels to weather when they are cocked will also move both keels ballast to weather.

If the windward keel is pulled out of the water, only the leeward keel generates a vector, the vector providing resistance the leeway, the canted keel’s vector also lifting the boat (lowering the effective weight of the boat) and providing righting resistance. Since only the leeward keel and rudder are in the water, that keel can be shaped like an airplane wing, designed for one tack flying right-side up. the windward keel out of the water. As the boat tacks, the new windward keel is lowered into the water and the new windward keel is raised. This raising and lowering could be done by using a second pivot point. It would be far easier than the system of raising and lowering the foil keels on foiling boats such as those in the America’s Cup Challenge.

If the pivoting keel runs aground it simply pivots rearward. If the keel breaks off, the boat continues sailing on the remaining keel.

An added benefit of outboard keels is that they have a longer higher number aspect ratio than the traditional keels. The traditional keel’ aspect ratio is defined by the height of the keel from the keel’ bottom to the bottom of the boat. divided by the effective front to back length. On leeboard keels, the aspect ratio is from the waterline to the bottom of the keel. If the centerline keel’ top is 1′ below waterline, the side mount keel’s depth is one foot longer. If the outboard keel is tall and its top sits 3′ out of the water, then the boat heals, the top of this keel will submerge adding 3 more feet to the length.

With the keels providing healing stability, the hull can be made more round shaped front to back, the round shape providing the highest amount of buoyancy per square inch of surface area. NO MORE NEED FOR AN EXAGGERATED PLAINING HULL TO GET THE BOAT UP ON TOP AND OUT OF THE HULL SPEED RESISTANCE OF 1.3 times the square root of the water line length. In light wind, no huge amount of wetted surface area dragging down the boats speed potential. At plaining speeds, where most of the drag of a plalining hull is due to skin friction, no more speed being held down do the large surface area / amount of buoyancy of flat bottoms plaining. No more driving the bow into waves, the waves coming down the deck and hitting the cockpit. No more waves shooting up into the air as they hit the leeward side of the front of the boat.
A broken off centerboard box or a keel can open the hull to flooding. A broken off lee keel described above would have little effect of the hulls water tightness.

Keels could be easily removable so that the boat is narrow for legally trailering on the highway. (Are J 24s legal to trailer on the highway???????) What would a Hobie 34 be like without that keel box?? An S2 7.9 without the dagger-board keel box that the interior had to be designed around.

No more shallow cockpits that have to be shallow to allow water coming from over the bow to drain quickly.

No more being 10′ out of the water when your boat capsizes and you are on the windward rail.

If the lift component of the 2 keels and 2 rudders is greater than the displacement of the boat, the boat lifts out of the water, the keels and rudders acting normally in light wind, the keels becoming hydrofoils in heavy wind. In that heavy wind, there being no theoretical speed limit. Size of boat becomes less important. ( a kite foil sailboard is only 4′ long) Do we know of any sailboats of any size with plaining hulls that would want to race one of these around a course?????????

I strongly believe that the sailing industry could swell if there were boats available for sale that had refinements of the above concept incorporated into them.

Where is the future of sailing????????

I then sailed with Randy Reynolds, on his R 21 – then the Sol Cat 20 – PMA worlds, i love CAT sailing and The Farrier 28 – with Dan.. I was told by some really good Multihull sailors.. Hold the main sheet – always.. Randy R. never lets the mainsheet out of his hand.. ever.. This was not the fault of the boat.. The Main Trimmer was way too late.. easy and simple fix.. wake up Main Trimmers !!! this boat is really powerful, and will be a great Ocean Boat – learning curves are hard sometimes.. Love the boat. Wish you all the Best with this great New Boat.

Randal’s responsibility as a harbor pilot revolved around guiding large ships into and out of Charleston’s difficult harbor.

Comment on Rules for sailing in high current venues by Spike Selig http://www.xssailing.com/news/rules-for-sailing-in-high-current-venues/#comment-54121 Sun, 19 Apr 2015 20:52:39 +0000 http://www.xssailing.com/?p=19335#comment-54121 The above article reminds me of a couple of past sailing experiences.
The first was the Y Flyer sailboat National Championship Held in, if I can remember 1970. The winner of that regatta won all races and the nationals. The last race, he was leading the race when he fell into one of those “Oh nooo!” holes in the shifty wind. Behind him a large raft of boats caught a gust front and came steaming down the lake splitting into two and passing him on both sides.This sailor, one of calmest and nicest I have ever known, ripped out a floorboard of his boat and started beating his crew as a raft of Y Flyers wooshed passed him, his boat still stuck in the windless hole.

The next year, the Laser National Championships, one of the first ever held, was held at the same location. The winner of this national championship was the same sailor that won the Y Flyer championships on the same body of water the year before.

The skipper who incredibly won both of these national championships was Randal Swan. a long time member of the Charleston Sailing Club, Randal Swan, who for a living was a harbor pilot in Charleston Harbor.
I sailed in both these regatta totally befuddled by the current. Each day of the Laser Nationals, I could see from the course a large sign sticking up out of the water off to one side of the course. The sign was unreadable from the course as it’s writing was on the far, useable side. After finishing the last race, I sailed over and satisfied my curiosity. The sign read “Danger!! Rocks!” the same rocks I just ran aground on.

Two years later I tied for first place in the eliminations in the Y flyer Nationals at Atlanta Georgia and took third place. Thankfully, Randal did not race in this race.

In 2002, I applied for a patent for a GPS modification which among many other features, corrected for current when sailing upwind. I plan to write a book on sailing in current shortly. Sailing in current with increases and decreases in wind velocity is incredibly complex. Stay tuned.

Comment on MXNEXT SAILORS DUKE IT OUT by Spike Selig http://www.xssailing.com/racing/mxnext-sailors-duke/#comment-49041 Fri, 08 Aug 2014 20:59:20 +0000 http://www.xssailing.com/?p=14996#comment-49041 Questions: Does this boat stay upright at the dock with the narrow hull and tall battened rig or does it lean over to one side as the Taser did?
How do you get off onto the dock? The video does not show what happened after the boat reached the dock. the bow is too narrow to walk on the deck without great tippyness and thus without gymnastics as happens when you try to walk around the mast on a Laser. Long bow will plow intoo waves rather than carry and lift boat up and over them. tall mast with no jib will try to round boat into wind when sail is out over water when healed. Long bow will stay in rather than lift out of the water in a planning situation with this “flat” front to back keel line cutting down advantage of planning ability, resulting in boat being stuck on hull speed when other planning boats lift over the bow wave and go faster than 1..3 times the square root of the water line length. Narrow waterline will be tippy going down wind resulting in crew having to do acrobatics to keep the boat from healing with the healing’s disastrous broaching tendency(ie Sailing a Laser in high wind straight down wind requires all you are capable of giving to avoid death role, broaching, and banging her in to the windward side of the boom). Adding crew weight will put outrigger type sides into water greatly increasing wetted surface area, the wetted surface area greatly slowing the boat down. Waves slapping these outward extensions of the deck will also pound in waves and slow the boat down. Otherwise, the boat is close to being right. Could you make another video of sailor walking up to front of boat from the cockpit and tying the boat to the doc? Also video of the boat in high waves and sailing down wind would, I think be interesting. To have a “diving bow”, the cockpit floor has to be high to quickly drain water coming in over the front and front sides. This means you sit on the floor with your feet out in front of you when not hiking out, Sitting on the boat rather than in it also can be a cold sail on a cold weather or cold water day.

while the other boat could have taken the main halyard and pulled. This would have
tipped the boat to get the mast released from under the bridge. Timing on both
rescue boats would have been critical, but I think it would have worked.
