    Default Polar Bear 2018 Video

    Anyone checkout the new Polar Bear video from Oct 2018?

    "Total displacement" makes me think. It's more complex than simply weight when it comes to producing a surf wave, as hull size and surface area make it harder or easier to sink a hull deeply at a given weight.....and its very much about how deeply the hull sinks into the water.

    I.e. a big flat hull is going to achieve a more shallow depth than a short deepV hull at the same or similar overall weight. And surf wave is going to be the roughly inverse amplitude of the hull moving water aside as it plows through the water. Every action produces an equal and opposite reaction......KINDA.

    Not that Robert draws any conclusions from presenting these displacement numbers, I just hesitate to relate them to actual results/waves with much meaning.

    If that makes sense. Not really a critique of anything, just a deep thought on surf waves, weights and wave sizes.....well not that deep, but whatever.

    Example: I know the Fi25 was really good. But it also was 1200# heavier than anything else, and has a deepV hull shape that lends itself to deep sinking. They even had a hydrolock issue related to this at one point. They sink like mothers!

    So it stands to reason that boat will do well.

    Meanwhile an equal sized boat with a much flatter hull (Makai) is running a lot less weight and is harder to sink. Thus producing a less impressive wave.
    The outcomes are going to reflect this discrepancy.

    Flatter hulls will need more weight at a given size than a deepV to make the same amplitude wave.

    So why is not everyone deepV if its more "bang for the pound?" (sounds dirty but isn't?) Well, I suppose its because there are tradeoffs in stability, the way the interior space ends up, wakeboard performance, etc....so each manufacturer chooses the shape according to their desired outcomes.

    More deep and potentially completely useless thoughts.

    Now to make chicken in the InstantPot.

    I watched it as well. Glad to see they were able to recover the footage. I feel bad for his community losing everything in the fire.

    Good surf video. Pretty worthless analysis overall

    Missing a few if not many of the best boats out there too

    Sems like a friend surf party. Which is cool. But reallly not helpful.

    I'm almost certain they planned to have an axis at the event, but maybe something happened where it didn't line up? Or more likely I'm just miss remembering things...

    They had a couple late back outs—oh so I heard. That’s what generated the Tige info I was referencing I think...
