Electric Sculling Drive.

Here in Malloca I have no way of testing the Scull Drive in ice but the next time I are going to make a test I will fill the test- pool with small pieces of ice and I will let you know the result.

I don't think you can tell from that. I guess it's better than not testing at all. But it looks like the shaft will be the one being damaged (if anything). It would be nice, though, to see some pictures of it in ice – even if just in a pool.

How fast does it swing – how many oscillations would you gather per minute – I mean the "life-size" one (I'm assuming the small one oscillates faster)?

The idea with the Scull-Drive is to use it on small boats, not on ice breakers. The scull frequency will not be very fast.

Haha, I wasn't talking ice breakers, I was talking small (ish) motor boats –*slow moving troller types and small fishing vessels. Nothing huge.

Would be kind of cool seeing a CG Icebreaker with swim fins.

We corresponded with Kim Prentiss down in AU.

Now, it seems israel is taking the lead with wingsails.

Hope you are doing well.

Hi Mark.
Are you still connected to any Wingsail project?

The Sculling future can change in China.

Sorry mate,

Love the artwork, but if it cost money, you have no chance in China.

I took this pic just last week, the whole boat would have been cheaper than your battery!

There is NO pleasure boating industry in China, simply because there is no where to use them, and most of the people could not afford to run one even if they were given it. They earn a dollar a day........and have a wife and kid to feed.

My Scull Drive is only a prototype and not designed for poor fishermen’s. The idea is to make Sampans for tourist’s trips in Hong Kong and Shanghais harbours with the same standard as the Venetian gondolas.

Oh well, good luck.

Hi Kjell, I'm new here, have you ever tryed driving one of your fishtails with an oscillating wind vane? flapping in the breeze, yanking the fishtail back and forth like?
