I am going to say it is kicked up at the end as when the boat is running at speed, the length of the un-modified tab would have it creating downforce, even when fully retracted.
With the "kick" in it, I would assume it would run clear of the surface and not exert any force on the boat.

Wouldn't the SSM VI drive throw a roost in the skiers face? I have seen them throw a roost a lot further than 200 ft.

Why??? I love speed especially in smaller boats, but the $$$ spent for this has to be unbelievable...

Maybe the upsweep on the tab makes the wake a touch more manageable for the insane skiier?

must be running deep

tabs are probably like that so they can get more bow lift. and the 6 is on there more as an unbreakable set up rather than a true surface drive.

the six is a fairly recent addition to these boats, there is only a handful running them so far, lots of early speed masters and shaft drive boats, these are cutting edge. Re Roost, you would be surprised how little is thrown up, they are run with fairly small diameter props that might have a bearing on it

If you get a chance to ask the builders of these boats, would you and let me know? I have a 24 that runs barely 80 and am thinking of doing some mods to increase. It is also a semi-vee. I thought maybe they were able to run with the down a bit and the end of the tab was on the same plane as the boat bottom so if it started to chine walk, it barely touched, but did not dig at an angle different than the bottom, therefore a smooth transition?

Serious machine.

But sitting here in Vermont is about as close to that thing I want to get.

135mph in a 21ft no matter who designed it will get someone very close to Kervorkian results.

Hopefully I am wrong...

That was only "60%" throttle. Wait until they open it up!
