And for the record, I have never owned either 1, but I did own a Eliminator Daytona 24 tunnel with a pod, w/ 2x 2.5 EFI Offshores, and it COULD beat you up in bigger water. At the same time I have been in many Mystic C5000's, and the ride has always been smooth/docile......
Everything is for sale @ a certain $$
Rocky's pic with the vette was epic.. LOL I can't have that **** on my board though.

Wrinkleface Now for cats which were the Second boat invented by man, when he could not stand on a his single log, so he tied two together, Look at the OSO advertisement up in the header on your right, you will see a cat “without” a pod or obstruction in it’s tunnel.
Now on a cat we have these two “fine” should we say hulls (sponsons) which are a big part of this boats efficiency,
You see we pay a horrible price for every Single square inch of wetted surface; the trick here is to keep this to a bare minimum,
Now just sticking some structure in there is going to cause drag in both the wetted and air resistance sides, No Magic here a price will be paid! For the wetted Side one would need to look at its angle of attack and the dihedral, Air flow we look at the gross cross-section, and then factor in shape, but that all goes out the window when you try to drive that Pig hanging down through water at high speed. The pressures = Resistance is amazing!
I have done testing on my outboard cats, the triples we needed a deflector system to protect the center outboards midsection (which is not made to run IN the water) I tested the boat using two engines Both before and after I glassed it on, made a - 6 MPH difference and the military boats loaded were only running @70 MPH in the Hot Air and Water over there.
Yes Years and Years back I read Talons advertisement where they claimed the water and Air being forced around their “Pod” actually increased the boats speed!!! Must be a “Magic Pod” anyway we got a good laugh out of it.
I have spent a lot of time on tunnel design on my outboard cats where I had to use everything but the dust in the air, you keep it simple, no complex shapes, the boats projected mass is what you start with here.
Slippery when wet. "POD" Free Tunnel through Common Sense Engineering
I.E. the "Tunnel Tab" would be a great argument here.. Most people think a Tunnel Tab is to help a boat get on plane or reduce porpouse. It's not, and can actually be a ridiculously dangerous if you're driving around with it down and water fills the tunnel and hits it.
In a true tunnel application, what the tab is actually for,(when racing) if the water is smooth enough they can drop that tunnel tab and raise "tunnel compression" lifting the boat further out of the water (hydrodynamic drag is greater then the aerodynamic losses) and pick up quite a bit of speed.
On some models of boats with pods out here on the West Coast they are equipped with 2 smaller tunnel tabs to create the same effect. Problem is people try to use them as trim tabs and end up barrel rolling boats every now and again.
That in itself kind of blows the sticking anything in the tunnel will slow ya down theory.
BTW for efficiency purposes.. Eliminator Daytona (Pod Boat) single Merc 502 (415HP if memory serves?) with a black hawk drive ran in the mid 90's..
Talon with a single HP 500 is upper 90's? (I think Hustler actually claims 100mph?)
