Those tabs look like they would barely touch the water at 60 mph even lowered. Is that the whole point; to prevent the burping air more than pushing down on the water? Or are they firmly against the water at those speeds?Most cats will have a porpoise zone. The 21 Liberator will hop between 60-75 in calm water. It does not hop in a 6" chop or more. Anyway, by having the tabs on top of the tunnels, you can put them down during the hop. This lifts the back and allows the trapped air to escape. When a cat hops, it's because the tunnel is compressing air. This lifts the boat. Pressure builds up and then "burps" out the back which drops the nose. Then it starts over again creating the hop. Once the boat gets up enough speed, the sponsons lift enough to create straight through air flow. This is where the hop will stop. Both tabs go up and down together.
Randy, I will be flying in thurs 2/23 for bachelor party/ Daytona 500. I plan on stopping by at some point as I am there till thurs 3/1. I'd be more than happy to take some running pics for you.
