Being "approved" and having a wake that skiers, trickers, jumpers and barefooters will actually all like may not be one in the same. The goal of this variable dead rise hull is to shape a wake that is preferred by these 4 disciplines over static hulls. The Gecko is an interesting option. Have read somewhere on another thread that the wakes are on the hard side. Cool looking boat but sure low to the water. Looks like it would gobble water over the bow very easily.

Thanks for your comments @DW. Always appreciate your input. Here are 2 configurations of what I think might work. This may work for trick speeds however the shorter contact time the plate has with the water the less time it has to affect a directional flow change especially at higher (barefoot) speeds. Which configuration would better achieve the desired affect?

@skiinxs - discussion similar to your idea. Agree that the hinge would need to be "hidden" in a step so as not to effect things. http://www.ballofspray.com/forum#/discussion/comment/103384

@"Eric Kelley" -show us what your thinking.

@MISkier - conceptual drawing, tolenrances or design would need to address that. @ShaneH - LOL...may improve barefoot wake and top speed in raised or partly raised position to appeal to the barefoot crowd not just the 23 trickers as you jested. @rodltg2 - nothing like the Nautique "Hydro-Brake". @Wolfeie - nothing like the Tige "T.A.P.S" system as this concept is more than a rebadged trim tab(I know convex hull part of "system). This would allow you to alter the dead rise and therefore the wake shape, planning attitude. AWSA may need to change ruling to allow boat design progression. @Wish - don't know why Nautique is exempt? May have something to do with the hydro gate only having 2 positions and not variable settings? I can imagine that there would have been much more incentive to approve Nautiques hydro gate system, already a long established supporter of the sport, than to approve a newer player with the Tige Taps system.

We have some great slalom boats out there but our trickers have been left out in the cold. What if you could have both without sacrificing either. Am thinking the adjustable plate and hinge, or maybe the whole boat, would need to be made out of aluminum? Actuators up to drop the back of the hull for a steeper, taller trick wake at slower speeds and maybe a better barefoot wake at higher speeds. Might up the top speed a bit by taking a bit of hook out of it. Down for slalom mode to lower the deadrise and flatten the wakes. Might make @eleeski happy!?

Try this

So essentially I can get a 91-94 Prostar wake in up to a 2001 MB Pro Boss 190? Was the Pro Boss 200 same hull just with the extra bump out the rear to make more room?

Not sure how that went. Maybe someone can enlighten us....

Mastercraft produced a great Prostar hull from 1991-1994. Great things are often imitated. What model years did MB Sports "imitate" the Prostar hull in the Pro Boss 190 and 200?

If I used my boat primarily in the ocean this outboard would be great. Reduced chance of prop damage from dunnage in the water. Easy to replace if hit and you can get the whole motor and drive unit out of the corrosive water when parked. And look at all that space. Thinking that the new era of 4 stroke EFI outboards would hold speed a lot better too for a better overall pull then the old school oil pukers.

@dihrdskir. Check out the thread "Skiing behind outboard boats". Looks like an Aussie boat company has come up with a clever boarding platform for outboards. Best I've seen so far anyways. http://www.ballofspray.com/forum#/discussion/12341/skiing-behind-outboard-boats

So a little hook takes care of it? Sounds easy enough...any other tricks?

Not much I could find on Team Talk. Talk of it but no solution mentioned.

@ozski , just couldn't help yourself...gotta say it gave me a good chuckle.

That boarding platform solution is genius. Any closer more detailed pics of how this works?

Have heard that there is a hull spray fix or reduction solution for this vintage of Mastercraft. Any pics or comments on this?

Ok...so I'm not the only one to observe that the swim platform looks like it could be lower...? Other items are far more important than this but...something I noticed.

I think it's a good looking boat. Never skied behind one. Really like how they windshield mounted the Bimini. Looks bitchin'. Only thing that looks a bit odd is the swim platform is very high up on the transom. Does it need to be that high to sit at the correct level in relation to the water? Had a 1988 Centurion Tru Trac II way back...Cool boat. Would definetly consider the CP if available as open bow.

Not going to see the end of this movie till next spring...well that's a let down.

As a very general rule most boats of that era turned x100 rpm of the speed they were going. 32 mph = 3200 rpm, 36 mph = 3600 rpm. If your rpm gauge is functional just set your speedos that way for now until you have the tools to fine tune it. Any early Supra ts6m owners please chime in.

Report back with speed and rpm data...something smells here.

Intersting that rudder torque can be minimal and the boat still drive well. I find that to be the case for our boat as well. Counterintuitive but it just is that way. Nice to get a boat that just "works" from the factory without having to tweak it.

Good point...what rpm are you at for the various speeds? You should be at 3400 rpm or less at 32 mph. If not maybe your speedo is messed up and reading a higher speed then you are actually traveling at. Have you calibrated your speedo through a slalom course?

Yeah...can relate to the sadness. Located in southern BC, Canada...Went for the last ski of the year today. Was awesome, sunny, air 73, water 55. All rain and cold moving forward. Sad...very sad...till spring.
