Finally pulled the Trigger on a GSA system.

Sounds good Boone, you and your family are always welcome on the boat. I feel pretty confident about doing the install, been watching the install videos for a few months now.

I will take as many pictures as possible before and after, I'll also do a little write up for any "issues" I run into.

There are only a few issues I forsee at the moment...
1. Power to the system. If I remember correctly from the ballast install I don't have power distribution block under the dash, only a ground block. So I will have to tap Clean power from somewhere else that is both fused and on the perko switch.
2. Trailer bunks. From what I remember the trailer bunks are roughly an inch pass the transom which could be problematic for installing the hinge for the plates. As well as catastrophic for the tab if I happen to forget to bring them up when retrieving.


Other project to work during install:
As many owners especially those with the Ve are aware when heavily ballasted or listed for surfing the swimstep digs into the wave and creates a second lip. I know many have cut their swim steps or just made new ones out of starboard or similar products....I am going to take a different approach. During my testing with the Delta earlier this year i was able to take a measurement of roughly how deep the swimstep was under water when everything was full. Roughly 4" while moving and 9" while at rest. I am going to put a 4" spacer between the swim step and bracket. This in theory will keep the swim step out of the water while heavily ballasted, but will NOT require me to redesign the Duffy Flap since the brackets are not moving and same goes for the FAE support bracket won't have to redesign the bracket.

So... If my logic is correct I will have a redneck version of a VX system, a comparable TAPS3 System with GSA, and eliminate the swim step issue.

Will you not have to completely re-engineer the swim step brackets to create clearance for the tabs when in stowed position?

My 2006 brackets would have been completely in the way and would have had to be rebuilt to be less bulky, raise the platform, and create clearance for the tab to swing up.

Maybe yours are different...

peel back carpet and saw off the excess, reattach carpet.

Yep, you're going to for sure want those out of the way for the install. Critical to get the hinges just right!

[talltigeguy]

Isn't the swimstep going to be much less of an issue with the boat not being listed? Does the GSA create much list when activated?

Most of the modern surf systems create yawl, rather than list, which has made most swimstep mods obsolete.

[Germaine Marine]

Yours being hip high and 25 feet long would have several guys with $100k + boats cussing up a storm. Love it when that happens.

A huge wave isn't the only reason behind enjoying a 100k boat. The amenities are amazing on some of these new boats.

I love the features and new boat smell personally

[UNSTUCK]

Ah yes, the new boat smell. Sure beats my musty, dank boat smell.

[dakota4ce]

The swimming step issue is more to do with width. The corners might scar the water.

What I was referencing was the actual physical interference of the swim brackets in relation to where the hinges need to be mounted.

Also, tall guy, a lot of surf systems create a list. I know transom lift is vital to the way GSA works. Yaw of the hull I have never really heard talked up?

The SurfGate/Nautique approach is primarily yaw based. The hull is held slightly "sideways" relative to the direction of motion (e.g. the heading is divergent from the bearing), and the side of the hull creates the wave. Such systems project control surfaces sideways beyond the natural line of the hull to impart yaw. Malibu likes to wave around their "delayed convergence" marketing phrase but it's really a hull yaw angle issue.

TAPS3, GSA, Gen2, and similar systems are primarily list based. The hull is "tilted" relative to the surface of the water, and the displacement of the hull on the deeper side creates the wave. Such systems project control surfaces down, below the bottom of the hull, as opposed to the SurfGate style projecting them sideways.

Arrives today, install starts tomorrow morning first thing.

TAPS 3 has some yaw in it for sure. I watch it yaw every time it engages. Also, that's why the tab has a 90 degree lip to catch and pull. So, the tab lifts for list and then pulls that corner of the boat a little for some yaw.

Anyways...that's what it looks like to me

You are correct sir, its a hybrid.

[IDBoating]

Sure, both systems have a bit of the opposite axis involved. That's why you have to countersteer against a TAPS2 (center tab only) boat with lots of ballast - it wants to yaw a bit. And obviously the yawed hull of a SurfGate-style boat is going to want to turn into the yaw angle, so again you have to countersteer. But the two systems obtain their primary effect from rotation about different axes.

[Thegerman618]

Thanks Mike I'll tap it there.

[Thegerman618]

Well....Dakota Sir....you are correct! The swimstep brackets are in fact in the way. By mocking this up by hand I am only able to to get 16 degrees of upward deployment before it hits the swimstep bracket. (I am at least 10 degrees off the suggested 24-29 degrees as instructed). They recommend 4" from the edge of the boat, if I jump that to 7 3/8" then I can fit the tab between the brackets and can get 23 degrees upward retract, but the actuator won't have anywhere to mount because if he beveled edge on the transom where the exhaust exits are.

I have sent my little puzzle problem to a Ryan at GSA see what he says. I am guessing they have already tackled this issue as there is a 22ve with the system installed. See what Ryan has to say in a few hours when he wakes up.

Keep ya'll posted, thanks for all the replies and assistance guys...

[dakota4ce]

I know when I was considering the same on my 24Ve, it was going to require new brackets for the swim deck. I was going to remove the factory ones, and modify them to raise slightly and be more of an L bracket than a triangle, if that makes sense. I cannot recall exactly what my plan was, but it was not too crazy but did require some fab work.

Also, I am quite certain that moving them inboard is not the solution for sure--4" from the corner is vital to making it work correctly. Find yourself a good welder in the area, draw it on a napkin, and fix it up!
