We have a 34' CHB trawler which is vulnerable to waves and wakes when at anchor.
For some time we have used Davis "rocker stoppers", 4 to a side, with good
results. Once we were less that 200 yards from a BC Ferry route (from Schwartz
Bay) and rocked like crazy until we got them down and then all was peaceful.

At an auction over the weekend we picked up two devices which have 4 flaps in a
square tray. They are on 14' of line, and the louvers allow water to go up, but
not down. I would like to know more about them.

Has anyone any experience with them? I don't see a name on the units.

Thanks - Chuck

Something like what you are describing is advertised in "Lats and Ats"
magazine as "flopper stoppers."

http://www.latsandatts.net/store/product.php?productid=16200

I Googled "flooper stopper" and got a bunch of hits.

That's it! I googled rocker stopper and got Davis hats, gigantic pneumatic
installations... I should have used "flopper", rather than "rocker". It's a
case of "too soon old - too late schmart".

The pair I bought have absolutely nothing on them to identify their brand or
provenance.

All best wishes

Chuck
