Whole Lotta Boinging Goin’ On


Here’s the latest Spaight Street Syndicate Update on the baker’s dozen Nite mast project:

Whole Lotta Boinging Goin’ On

Yesterday was boinging day at the Spaight Street Syndicate. With a baker’s dozen of Sitka Spruce Nite Racing Masts nearing completion, it was time to determine the boingosity of each. Freshly back from the American Magic camp in Barcelona, the smart person job was handled by Kyle Navin, while the old man (the reigning Nite National Champion) recorded the data. “Funny, but every time the weight needed to be hoisted onto the sling, the two old guys had “business” to conduct on their phones,” commented the junior Navin. Little did Kyle know, but this was actually a training session on the fundamentals of business management–the day’s focus being on delegation and empowerment.

 

Precise boing data was collected with a top secret amount of weight (it was 80 lbs.) suspended at the mast center, with readings taken at the bottom third, halfway and two thirds points. The builders were pleased to note that the boing was remarkably consistent from side to side, even prior to final tuning. Over the range of masts, centerpoint boingosity was recorded from 3.2″ to 5.8″. In the days ahead, comparisons will be made to other existing masts that have performed well on the ice in the past.

 

Key questions–
1.) How much boing is ideal?
2.) How much is too much boing before mast failure?
3.) Since we now have the option to lose the lead, are softer masts more practical? Inquiring minds want to know.

Trust The Engineer…Or Else!

Since it was determined last weekend at Lake Pepin that I have a weak spine, this weekend it was time to man up. First I removed the ragged skin to the closest bulkheads, sideboard or stringer. Then I cut out the what remained of the old spine. The original T-beam was constructed of 5/8” Sitka, 2-1/2” wide with triangles underneath. I made the new T-beam out of 1” x 3” White Oak with two verticals on the bottom, triangles underneath and horizontally at the bulkhead joints. For additional peace of mind, I added a layer of 45 degree carbon and a layer of biaxial carbon around the entire beam, plus one more layer of carbon on the top. And finally, carbon gussets at each of the corners were the beam and bulkheads meet. This construction should be dramatically stronger than the previous, which would have been fine, had I just followed Pat’s plans.

 

Rather than using a traditional top-mounted mast ball track, which would have spread the load out across 14” or so, I used a 6” countersunk style. This required the removal of a fair amount of material directly under the mast ball, when the shorter length was already concentrating the load in a smaller area. The mistake I made was not accounting for these impacts. But the countersunk style looked cooler. (That’s what we call “solid” marketing thinking!)

 

The spine didn’t actually collapse, rather, the track twisted, blowing out the side of the original beam. It was breezy that day on Lake Pepin, so in addition to carrying a bunch of lead, the stays were slacked off, which caused more side load on the mast ball, hence, the twist.

 

Hopefully the Northwest will be “On” for the coming weekend, so I can give Lorem Ipsum another shakedown, and try to catch Pat!

Confusion Reigns

“Not sure what boat season it is.”

Daniel Hearn sends word from the Spaight Street Syndicate that he’s unsure what boat season it is. Minnesota’s Dirk Siems sailed his DN on a sunny April day on Otter Tail Lake yesterday in what has to be some sort of late record for Minnesota DN sailing. 4LIYC sailors are returning from Ivanpah, Nevada, with some trophy hardware awarded during the Blokart dirt-sailing event. (More on that tomorrow.) No wonder we are all confused!

Dirk Siems usually finds the first ice for the Western Challenge in MN and now he’s on the hunt for the last ice of the season. He sailed on Otter Tail Lake yesterday, April 9, 2022.


Geoff Sobering won the overall and his division at the 2022 Blokart North American regatta at Ivanpah, Nevada.

And now for something completely different, via Daniel Hearn at the Spaight Street Syndicate.

The World According to Dash
If you’re like me, time always seems to run short when you’re prepping for the first regatta of the season. So, when nature calls, “ain’t nobody got time for dat.” Well, fret no more! Just get yourself a combo rolling work bench/changing station, like my Pappy’s, and do what I do. Drop that deuce right in your pants. Faster than a Struble start, you’ll be back at it before your runner even cools. Critical Hack–Make sure your sanitation engineer clears the bench of any carbon fiber dust. That can be very unpleasant on a fella’s bum.

Spaight St. Syndicate Update: Flat Pack Masts

Mast mania

Daniel Hearn’s mind wanders over to Ikea iceboat mast section…

Ikea Masts

Ingvar Kamprad built a $40 billion per year enterprise selling furniture in boxes. His future took shape when he realized success depended on the simplest, most cost-efficient distribution from factory to customer. The founder of Amazon, Jeff Bezos, figured out he didn’t even have to make anything to become the richest man in the world (never mind the divorce). He just had to have the best distribution system anywhere.

 

I’m sure our first billion is showing up in the offshore shell company bank account as I type, now that word is out that you can buy a C-Skeeter mast in a box. If you’re looking for my name in the Pandora Papers, however, don’t bother. The Corp will eventually trace to my wife’s name. She’s the smart one in the family!
