OK, I've driven myself nuts for two months trying to figure out what a boat part is, and I'm ready to admit failure.

On the bridge of the Billikin, to the left of the helm, in the middle of the center window, is a circular frame about 18" in diameter, with what looks like a knob in the center of it. The area inside the circular frame appears to be clear glass. What is it? :shrug:

Will some salty kind soul please enlighten this flatlander? :help:

It's "sort of" a wiper. As TWB said, it's a "spinner" screen. The glass inside is actually mounted on the center post, what Old Coot referred to as a knob. The glass is balanced, and the entire pice of glass rotates at high speed. Anything touching it is thrown off.

I don't have an answer for when they catch King v. Opelio. I assume it's a location thing.

I enjoyed the series, but I wish they had gone into more detail on the reason for the end of the derby fishery. In separate reading, I have a sense that the number of crabs increases when the catch of other fish increases, since crab larvae are a big part of the diet of bottom fish. When cod, pollock and bottom fish population numbers are high, the crab numbers drop. In some ways, the Bering seems rugged and remote. But my sense is that the balance between fisheries has a big impact on volumes of catch of each species. I hope there will be another season of the series that also explains some of the mysteries.

I thought I heard a small explanation for the end of the derby season being that they were trying to make crabbing less dangerous by ending the "race" and having guys working around the clock. If each boat is allotted a certain tonnage, they figured that the crews would work at a more "normal" pace instead of trying to get as much as possible as fast as possible.

Alaska has already done away with several other derby style fisheries like halibut and black cod. What they are doing is assingning Individual Fishing Quotas(IFQs) to the various licence holders of the particular fishery. The amount of the IFQ is determined by how much catch has been landed by that licence in the last howevermany years. there may be a bit more to it than that, but most of the determination is by amount of catch. What you end up with is a set amount of biomas each year that can be caught. People can sell and lease there IFQ's like a comodity, at least they could with halibut and sablefish. Because there is a set amount for each licence, there is no longer any need to fish through bad conditions or work 72hrs strait. It's safer, and easier to manage.

I may have skipped some of the deatils of IFQs, but these are the main points.

We use them on some of the CNC machines at work. They're marketed as a "Visi-port" for machine tools. Not sure what they might call them when they market them for marine use.

They use either an electric motor or an air motor and they spin a plastic disk at a high RPM. It basically spins fast enough that nothing sticks to it and everything is flung off of it.

Now and then we have to wipe some of them down if there's to much oil in the coolant. Once in a great while we have to replace one because a 3" drill slug comes flying out and explodes it.

Don't recall how much they cost. Can check if anyone is interested.

Did a quick google and came up with this.

I'm sure there are other manufacturers, but Speich has been making clearview screens since 1938.

For those that want one, they run around $2500.00.

Here's the breakdown....

This unit is designed to be installed in a circular hole cut in a glass, wood, acrylic or metal surface (1). The unit is assembled by flange and counterring (5), made airtight by neoprene gasket. The fixed hardened glass disk supports the motor (4) which rotates the optically rectified glass disk. On request the unit is supplied with a heating element (6) to prevent condensation and formation of ice.
