Big cats and tunnel tabs
Last fall in key west I noticed some of the big cats mostly the MTI boats had lexan tunnel tabs. Can someone explain the reason to use lexan instead of aluminum? I am guessing that the lexan will flex minimizing the stress on the tab and boat. Also what is the life of the lexan?

My understanding is that there is some advantage to the flexibility of the lexan in the efficiency of the tab. It was explained by someone racing with one that the curvature gives better lift and less flow interruption which means higher speeds. The old tabs just had a joint and pins, the new ones seem to just bend downward when activated.

I would assume they are set up the same way we are and we have no hinge. The assembly bolts directly into the tunnel and it flex's downward. Remember that we are not moving the tab more than 5 to 6 inches.
