Surf Tabs?

[snowboardcorey]

Deploying a tab would create "lift" on that side. Same effect as a center mounted trim tab, when down it helps lift the transom higher in the water/pushes the bow lower. This is why some ski boats have "hook" in the transom of the hull.

At 10-11mph you can't create much lift, but you can push the water to help shape the wake.

At 10-11mph you can't create much lift, but you can push the water to help shape the wake.

I can see that almost the same as adding xtra lbs to push the water down further-as long as the balast can overpower the lifting effect of the tab at 10mph ---kinda creating a lower/deeper hull line with the same amount of ballast

ragboy on ww did some testing with the platform off of his old tige and iirc, taking it off had adverse affects on the wake. seems that the platform helps.
will be real interested to see some a/b comparisons if that is possible, but seems that this will be a lot of cash for not a big improvement..


on a related note, the install looks top notch. nice job

I'm very interested in the raising of the swim platform. Does it help get it out of the way of the wake and create a better (higher, longer, deeper) wave? I have been surfing behind our Moomba OBV for a couple of years now and had heard this change made a difference on other Makes of boats out there.

Figured you guys might like some photos of an install we just did. We installed the outside "surf" tabs and raised the swim platform about 2" (using spacers between brackets and platform) to get better clearance of the wake and for a better bracket location for the actuator.

some info for you to look at..

That's good stuff Sandm, and I respect everything that Ragboy and the Wake9 folks have done for Wakesurfing.

Aside from a replacement / mod to the swim deck, have you seen the results of simply raising it up a bit with spacers?

nope. I just remember him saying that removing the deck had adverse effects on the overall wake. that the best solution was reshaping it and cleaning up the bottom of it.

This may have been posted, but like Sandm said, I think the key is a completly smooth bottom, with zero lip on the platform.

[jmeacham]

Good point Dusty. I do recall someone mentioning that the lip of the deck was the largest contributor to hindering the wake. I was chatting with the local Moomba dealer shop guys and they said they could "fill" the deck with foam and spray fiberglass over it to harden it.
