New take on the "old" drysuit

Post sunset sunset

40 knots of wind, -3 degrees wind chill and thankfully I didn't fall through the ice this time.

Shipping traffic

Two days ago I saw the Arthur Anderson, sister ship to the Edmond Fitzgerald way upriver on the Fox River being loaded up for another run. They always run as many loads late into the season as they can before the ice gets too thick to transit the Bay of Green Bay and the customer is forced to use rail to get their goods. This afternoon, I caught her headed up the channel (note : the Coast Guard pulled the channel markers out last week) and a few minutes behind her was another vessel that I don't know the name of, but looks like she might be older than the Anderson. I'd bet that the second ship had been waiting in port for the Anderson to head out to clear her a channel north. Its not an easy living aboard ships like these, especially this time of year.

I got these shots before each ship literally vanished into the snow squalls blowing in.


As they headed out, the winds were gusting into the 40's from the North West and as you can see, we have plenty of ice on the lower half of the bay.

The shots were difficult to get since all my long lenses are at the office in town. I shot these using the little Canon SD750 at 3X zoom through my 10x50 binoculars through the deck doors in the backyard. Less than desirable, but it worked.

Sorta.

UPDATE : Monday morning, 8:15 and the Anderson is headed back in with a load.

Epic Sunset

No words needed other than a footnote that I fell through the ice to get this shot. ;-)

Review : Maui Ultra Fins

I'm a huge proponent of fins. I see so many people who are struggling with a board, or a their sailing in general and they're all focused on the rig or something else when the problem stems from their fin.

People spend thousands on a sail quiver and almost nothing on fins, which are equally important in terms of board control and handling.

I recently got to test out some fins from Maui Ultra Fins and while I'm still puzzled about their claim of "Advanced airfoil design" since we're using them in water and not in air, I'm pleased with their performance. (Hey guys, drop the "air" from the tagline)

One thing about these guys, they "get it" in terms of what matters. The number one most important part of the fin is its foil. If you get this wrong, it wont matter what the outline shape is, the fin is gonna suck. The foils these guys use are really good - almost supercritical in design terms for how the foil keeps the flow attached even at crazy angles of attack (the angle of attack is the angle of the fin against the direction of travel - too high of an angle and you get a stall and stalls are bad). When I'm buying fins, I'm always looking at their foil first, square area second, length third and lastly outline. Anyway, back to the foil...

The feature about the foil that you'll appreciate is this : No spinout.

Its true, really it is. No gimmicks, no hype. The foils keep the flow attached and also shed separated flow caused by a bad board/fin/air interface in wicked chop.

I tested their all around bump and jump fin at Kanaha, overpowered on a 5.3 on the Starboard Kode and I really put it through its paces with balls to the walls downwind runs, hard upwind drives, and broad reach sloppy sailing that would make any fin spinout.


While I could get the fin into a flow separation position, it immediately reconnected and continued sailing as if nothing happened. Mind you, this happens in less than a second and I really had to work hard to actually get it to happen in the first place.

Once I had a good idea as to how the fins reacted to spinout conditions, I took them through a few tests that I knew would also be interesting - stall testing. To do this, I would sail as high into the wind as I could, forcing the board's angle of attack higher and higher to get the fin to stall and stop "flying" as it were. Could I get the fin to stall? Yes. All fins will stall above the critical angle of attack, but what was really nice is how the fin handles under a stall and how easily it reconnects and resumes "flying" with good water flow. This testing shows how good a fin's outline works in terms of dealing with tip stall (stall that begins at the tip of the fin) and stalls caused by the interaction between the board/water and fin. The net result, the fins handles great even when you beat on it.

There are a lot of fins out there, and most people buy them based on outline (or planform) and length. What they need to know is foil and square area, then worry about length and outline for performance optimization.

Remember, a good fin can make a bad board good and a bad fin can make a good board suck. So, before you give a board low marks, play with the fin. Feel free to ask me about problems with your board, etc. I'd bet I can make you love your board again!

If I had to make a proper analogy, its like having traction control and anti-lock brakes for your board. They keep you out of trouble and make you a better driver.

Can't wait to test out Ultra's twins on my RRD WaveTwin. ;-)

...and flights are only $600...

Total epic swell and flights are cheap.... DAMN!

OAHU-
900 AM HST MON DEC 1 2008

Surf along north facing shores will lower to heights of 6 to 10 feet today then increase rapidly late tonight to heights of 25 to 30 feet by sunrise Tuesday.

Surf along west facing shores will diminish to heights of 3 to 6 feet today then increase rapidly tonight to heights of 18 to 25 feet by sunrise Tuesday.

Surf along east facing shores will be 1 to 3 feet today and 2 to 4 feet Tuesday.

Surf along south facing shores will be less than 3 feet through Tuesday.

Outlook through Sunday Dec 7: a pair of storm systems passing northwest of the islands is generating a series of well above normal open ocean swells aimed at the main Hawaiian islands.

As one northwest swell departs the island scene, two additional swells are on their way here. One will be reaching the north and west facing shores of Oahu tonight with surf reaching warning levels. A reinforcing northwest swell of equal size and with a more west component is slated to arrive Wednesday night. It will finally peak Friday before a gradual decline through the weekend.

Surf heights are forecast heights of the face or front of waves. The surf forecast is based on the significant wave height in the zone of maximum refraction. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
