2020 Season

Thunder Bay, Ontario….

…was still sail-able as of two days ago! Mike Madge and his friends are still sailing out there- Way to go Mike! There are more than a few of us out this way that wish we were there with you!

You make know that Mike is often the first person to get out every fall- Could be that this year he is the first and last person to sail on hard water. Kind of a cool statistic!

Keep it up Mike- be safe and let us know how far into the spring you can actually go this year-

See the fun here:

Potential Sail-able ICE!

No joke- Sounds like there may be an option up in Canada if you are REALLY jones-ing for some mid-lake social distancing….

Andre’ Baby sent the following:

Hello All,

DN sailor Marc Tarini photographed checking ice a few minutes ago, in the middle of Lac du Huit near Thetford Mines. He mentions there is still 15 inches black ice underneath 4 inches new snow.

Cheers and Happy Easter to all,

André

Chad Atkins wrote a good article about these proposals in the September 2019 issue of RUNNER TRACKS- He works with composites for a living and has been building and sailing DNs for decades; he is very qualified to comment and his opinions carry a lot of weight. Click the link and go to page 20.

If you still aren’t sure re-read the following explanations and opinions from Paul Goodwin- DN Class guru, builder, engineer, tinkerer and all around good guy:

My take on the 2020 Proposals – Paul Goodwin

The first two proposals are to change specs that were written when the class first made the transition from wood to composite masts. It was clear at the time that the composite mast would make the older mast technologies obsolete, at huge cost to class members. This was justified because we were breaking the older masts at an alarming rate. The idea behind the minimum weight and balance point specs was to reduce the incentive to constantly look for the latest, greatest, high-tech (and expensive) composite mast material.

1) Deletion of the minimum weight for the mast –

I think removing the minimum weight will not be good for the class. The intent of this spec is to discourage using exotic (and expensive) materials. High modulus carbon fiber comes to mind, but there are potentially more exotic and expensive fibers available. I believe eliminating the min weight will accelerate a technology war leading to lighter and more expensive masts. Sailors will have mast envy, with the perception that lighter is better, driving the cost of masts ever higher.
My Vote: NO

2) Deletion of the balance point on the mast –

The reason for the balance point was to make a builder put some of the ballast up higher in the mast, rather than building a super light mast with a big chunk of weight at the base. I think the spec is still valid. I don’t want to make it easier to build super light, expensive masts. In the overall cost of building a pre-preg carbon mast in an autoclave, the time and cost of adding ballast is insignificant.
My vote: NO

3) Allow runners to be built of any material –

I think this proposal has no merit at all. I challenge everybody to think about how they would use this change to design a runner body that reduces the cost, and at the same time remains competitive against the super stiff lightweight carbon bodies that will be coming when there is no restriction on design and material. The DN is not the class for a rule that allows unlimited use of exotic materials.
My vote: NO

4) Amend the minimum thickness of insert plate to allow commercial material tolerance –

This one makes sense. The reduction in thickness allows use of commercially available steel, which can reduce the cost and is easier to find. The change is so small that it is insignificant for performance.
My vote: YES.


New Vintage DN

We have a new sailor in the fleet- last season Jim Floyd picked up this classic and has her back in action-

Any idea what year that sail number was issued? Has to be late 1950’s?

Here she is- Note that it says “Blue Streak” on the side- wasn’t that the original name of the DN design?

All kinds of questions- no matter what the answers she looks good!

Jim says “Here she is, by the way. Unsure of age. But like my 1960 rowboat and 1972 Hobie14, we are already engaged in a love affair!!!

We feel your pain, Jim! Look forward to seeing you on the ice this winter-

Think ICE!


SKUNNERS…..

Over the years many options have been pursued to make sailing on soft crusty snow ice (aka the dreaded “styrofoam”) possible and fun-

“Skunners” (a ski attached to a runner) seems like a good solution and Denis Guertin has built a really nice set- Pretty slick, no pun intended….

To take a look at how he did it and see them in action read on!

I will try to explain how I built them as best as I can, but please excuse my english which is sometimes french-glish !!

First of all, I grooved a long slot in the skis in order to use my Sarns bullnose runners and to have them go through the ski. The runner exceeds 1/2 inch under the ski. I used a piece of HDPE (High density polyethylene) to double the ski, but after all, I am not sure it is very useful. Maybe only the ski could be good. I used this HDPE because it is very strong, and very slippery on snow or crust. But a ski is also very slippery !!

On top of the ski, I wanted a system that would not need to drill holes in my runners. So I used HDPE 3/8 thick and cut the shape of the front of the runners so I just have to slip it into the shape and it is caught there. I bolted the HDPE pieces on a aluminum angle, and bolted the aluminum angle on the ski after. Both 3/8” HDPE pieces, plus the 1/4” runners equals exactly 1″, which is the capacity of the chocks. Note that you have to adjust the bottom of the HDPE piece height to obtain your 1/2″ of runner under the ski, depending on the thickness of the ski, which is not the same in the front than in the back.

Once the runner is slided into the shape, I had to secure it in place at the heel.

Here is a video of the skunners in action 2 years ago.

I hope this will help you…. Good luck !!

Hoping For A Happy Ending

Denis Guertin checks in from North of the Border…. Like a lot of us, he could use a happy ending.

Sailing Over The Border

As we watch little waves lap the muddy shores of our beloved lakes, there’s a different story up north. It seems that the Fat Lady was stopped at the border and could not get into Quebec. Denis Guertin has this to report:

MONDAY: Today was just crazy speed sailing. The south portion of the lake is a North – South orientation. Today’s wind was South and really good for our DN rigs. We just sailed tacking upwind to the South end of the lake, and then sailed high speed downwind to the island near my camp.
We had to stop at 3:00 because Frank had a side stay just about to break. In fact, it is the short cable used to lengthen his DN sidestay to fit the Whizz that was the problem. We were lucky that he saw it before it breaks far away from the camp !!
More sailing in the forecast for us… maybe Wednesday if Frank is free from work. Just a bit of snow expected tonight, but nothing serious. Forgot to mention that we had 4 DNs sailing with us this afternoon…

“FRIDAY: I got here in Lambton at about 2:30. I did not even care to walk on the ice and decided to rig my Whizz to enjoy that nice little breeze that I felt on the shore. So I put my skunners just in case the surface would be too soft.
I jumped into the boat, downhill from the shore to the lake because the water level is so low… and stalled in 1,5’’ of sticky wet slush. I tried to get going but the wind was not strong enough for this sticky slush. I went back to the shore!
It will freeze hard tonight, giving me one of the best ice of the season tomorrow.., oups! Sorry… I should say an acceptable ice tomorrow!! But the wind forecast is one of the worst of the season!!! But the boat is ready to go… just in case!!

SATURDAY: My boat has been laying there all day, waiting for just a little breeze to come, but nothing came. I know it must be difficult for you to have this ice just under your eyes and not be able to enjoy it, but can you imagine how it is for me to have it just under my FEET and not be able to enjoy it.

It will freeze again tonight, rain expected tomorrow at around noon, and SE wind early in the morning. Guess who will sail in the morning tomorrow?? The ice is amazingly smooth… oups, sorry again!! The ice looks OK, but we have seen better!! The frozen slush made like a topping of icing on a cake!! No more snowmobile tracks, all even and smooth as far as I want.

Stay tuned for the end of the story tomorrow… hoping for a happy ending!!”
