Direct Drive Surf Report - 99 Sport/Air

[Tom351]

Here is mine with the following setup- still listed, but not as much....(475lb offset instead of 800lb)
Same gate with the edge "winglets" added- not sure if they helped or not...
800lbs in rear trunk
370lbs in belly ski locker
800lbs on rear seat (centered)
275lbs behind engine (centered)
475lbs next to engine (on surf side obviously)
1 person in boat
(I wanted to try the gate higher but did not have a good chance to swap faces... will next time)
10.5MPH on GPS

Wave seemed steeper and bigger (makes sense as the weight is now farther back in boat compared to last time)-
Was able to ride the wakesurf board for good amounts of time - but still prefereed my 6'-0" ocean board because it let me drift a lot farther back and still able to recover.
Boat was more enjoyable to drive with "less list" and weight farther aft..

Also, Zeckto13: How do you fit a 750lb bag on floor behind the engine?....it seems like even my 475 would not really fit back there....

[zeckto13]

Looks good! Thanks for posting. I think the belly weight definitely cleans up the top face. Did you try swapping the 475 with the 275? Compared to your video earlier of your buddy, looks like a comparable wake with less list so that's good...helps with the driving/safety.

I wanted to put the 475 behind the engine, but it just seems like it would not fit there- the bag is 20" wide, and there is at most like 12" between the engine box and back seat.

[zeckto13]

Ya I hear ya. I was skeptical too but ended up putting my 750 there which is also 20 inch wide and was surprised how it still filled out nicely around the engine box. I actually filled it all the way as much as I could. Food for thought.

I guess maybe it ended up filling more vertical around the box. Helped keep the 750 on the seat too. Will take a pic next time.

Pic of the same wave without rider- my favorite part is the steep section/curl right in front of the whitewater pretty far back-

[zeckto13]

Nice! Looks great! Man I wish the season wasn't done so early up here in AB.

Got back out this past weekend- used same ballast config as before, but swapped gate face to one that could be run higher (without extension to reach into step)- wake seemed about the same....pic at 10.5mph riding ocean surfboard- my wakesurf board worked much better at about 9.5mph.

Good to know. Wave looks really good! Got a pic of the different gate? Gonna be 8 months till I get out again...ugh.

Yep- pic below- 8.5" high X 11" wide- 45degrees- shown next to other gate for reference .. Also, our lake is down about 3' so was only surfing in 10-12foot depth instead of 13-15'..... So maybe the wave would have been better this time if we had the deeper water.

[zeckto13]

Thanks. I think I'm gonna build the next one at 19" long by 11" high. My last one is 9" high. 11x19 is really close to the Ronix size i think. Will post results in 8 months...hah.

Yeah, I've been wondering if a larger face would help- don't feel too bad about the 8 months- I bruised my sternum slalom skiing that last time out, so my season may be done as well.....

[zeckto13]

Speaking of slalom...check this out...reallllyyyy wanted 6 ball. Sorry for the tangent. Couldn't resist

[Tom351]

Ha, yeah, you almost ate the 6ball!
