What kind of tunnel is this?

And then I believe this one must be the Fastcat for 3,5 cc

Nope, that one is the predasessor to the fast cat, should be 29”. This one is a fast cat...

Nice. You don't see the old boats that look that good anymore!

What a NICE boat !!!
Ok, it looks like mine has a different shape behind the pilot. There is probably other minor differences as well. Thanks for info

Thank you! Yes, the Fast Cat has a different shape cowl and the hull is a bit shorter than the earlier hull and slightly different bottom design (shallower tunnel depth and width I think) as well, don't know if there was much of a performance difference though. All of the Prather tunnels were designed to use a turn fin though. This one is actually a fairly new build, put it together a couple years ago, still have a NIB Lap Cat 1 and the full array (31", 40" and 46") of the Deep Vee's in the build que. I don't race but really like the old Prather stuff....

Racing has my main attention, but sometimes I dig out some oldies just to do something different. I still have a few NIB Dumas wooden kits on the shelf
