Unlinked can be used together or seperately, hence more control and more options.  


20-25 of true wind angle at any speed the boat can sail at would be a major breakthrough (state of the art is about 35).  Have you any proof that it can be done?  By proof, I mean gps tracks or sailing alongside another boat.

How does dual unlinked boards give you more control while sailing? Kinda sounds like your ranking my chain on this one.

So basically until someones else tells you or shows you what I'm talking about in there own words your still in disbelief.

Hey man I gave you an answer on how to sail higher to windward you can keep chasing your tail and or follow the herd good luck to you.

With in line linked rudders Like I have shown. You can sail as close as 20-25 degrees to true wind at almost any speed the boat is capable of sailing .

Its not a matter of ridding and relying on a single aft foil its a matter of being able to hold the boat at that heading at any speed and making the sail work. Not speed of flow over a single fin/ foil/ or board. Thats the benefit of dual linked counter rotating boards. It doesn't require high flow rate over boards or a highly crafted foil shape to achieve descent performance to windward.
