Water Ballast Scoops

I have been looking around for water ballast scoop ideas.  This approach seems much more attractive than a pump and a bunch of valves and hoses.  Control from the cockpit is key.  I have not found many designs or pictures.

The boat will need four scoops for two ballast tanks or some sort of interconnect that balances the tanks.

Some people use Andersen Super Mini Special dinghy bailers  These look heavy and expensive although durable. They may be a bit small.

Here is a good looking carbon design.  This is the only picture I found and it does not show any of the internal mechanism

Jan Gougeon's boat Strings as well as his earlier designs used this type of system.  Again, I am lacking details.   Here is a picture of a control center for Strings' ballast system.

Perhaps YOU have some experience you could share with me.
