Default Tunnel Tabs on Cats

I would like to hear from those of you who have some experience with Tunnel Tabs on Cats. I am buying a Liberator 24 with two 300x Merc's and I have seen some Skater 24's with tabs and read a little on the subject from some on this forum, but I am really curious as to the need for them, what their benefits are (if any) and how well they work, how big do they need to be, etc. I would also like to hear from users of these tabs regarding their techniques when using the tabs. As you can tell, I'm in a learning mode and there is no substitute for experience. I have none so I'm hopeing you'll share yours with me.

Have you ever had a ride in a 24' with 3 liter motors? Do the math- your boat will porpose like no other. Compare the 2.5's to the 3 liters looking at the weight only, you shall have your hands full...... please do some research if it's not too late. Good luck

Default Thanks for the reply

It was nice to hear from someone with experience versus opinion. I have some concerns, but Dan Weeden (Cougar), Hledin (Skater) and several others with impeccable credentials have echoed your words. Dan was very sure I was going to love the boat. I'm only just really curious about this tab thing. What has your experience been with the boat? Does it porpoise and if so at what speed and can you just drive right thru it. Do you consider it a big deal or not? Have you considered the tunnell tab that Randy is developing? Hledin said the speed that he experieced the porpoise was around 72-75 and it disappeared by 80. He indicated that you could just blast thru it without much trama.

The weight difference between 2.5s and 300x's is about 100lbs per motor . The 2.5 weighs about 375 and the 300x is about 475lbs. good luck
