Sail cover identification help please

[Timm R Oday25]

My neighbors bought out an old building . The previous owner also owned a marina in Door County . She left three of these sunbrella covers behind . At first I thought they were covers for a mainsail . The longest is 20’ . There are a pair of square ears on the end . Any idea what these fit ? Any value ? Any interest ? Thanks

Spinnaker sock.

Thanks .What are the ears for ? How do I know what size spinnaker ?

 

[sail sfbay]

Is there a ring at the top? Is there a line on it? What is the length? Length will determine the spinnaker size. No idea what the ears are for.

No there were no rings or line. There is a small vented square on top . The bottom is open witha few reinforced holes every few feet .
The largest cover is about 20'

It sounds like the control lines are missing, I think. If the reinforced holes are on opposite sides of the cover, then dual control lines would weave through the holes to the skinny end. There they would tie to a downhaul line via a pulley. It's not the easiest sock to operate but it works.

The sock I have has little rings inside the sock. And it twists and wraps and generally irritates me almost enough to buy an ATN sock.
