    Another GSA thread

    hi all, had several sessions to run my 18 R23 with GSAs this year and feel like ive run it enough to give some of my insights on the wave for anyone out there thinking about doing this to an older z3/r23 (or even z1) with taps3 or no plates.

    bottom line, no question the gsa surf wave is better stock or even with "light" lead than taps3. It's got a more mellow transition and bigger with more push. That said, i still think it's better (one of the best ive personally ridden) fully slammed. More detail follows....

    I typically run 900-1200# additional lead plus factory water sacks. taps3 wave was great with this setup. Last week went out with "only" 270# extra lead on each side (aft under bags), all my other lead left out. no question it was a better wave than with taps 3 plates. really nice, clean all the way. also, because port side cleans up better on my boat i can setup for a clean goofy wave and still run transfers with solid waves on both sides. the wave is for sure as good as most everyone will ever need, and i will use that setup when i don't want to mess with these extra lead since i leave the 270 unless trailering long distances. All that said, I still like the wave better fully slammed with all my lead. It is as good if not a better wave than any I've ever ridden, any boat (bu 22vlx and 23lsv, nautique g23 & 25 rzx3, Sanger 23, z1, taps3 r23).

    The extra lead adds extra push at back of wave and when i run faster (11.4) it's so long with so much room for recovery when learning tricks its very forgiving. There's firmness throughout the wave, so you don't have to pick the exact spot to boost for airs (like at the very back on a Malibu lsv). For example, you can either air further back or closer to the boat after picking up speed. Only downside, which is really a personal preference for some, is it is a relatively steep wave (still less-so than taps3). more speed and taps adjustments help a bit, but you could also dump some of the ballast and that would probably mellow it more.

    anyways... hope that gives folks some insights if you are thinking about doing it, I'm glad i did. In the end it may just depend on how much tinkering you like to do on your wave (i.e. wave snob lol)

    rider in first two pics is about 5'5". this is slammed setup. other is my "medium" setup, about 800# total extra lead. i both cases only me and one passenger in boat.

    Thanks for posting the update. Glad to hear you’re satisfied!

    Got my GSA plates last week. Will hopefully be installing on my ‘18 RZX2 within the next week or two!

      Besides being able to change sides quickly does the GSA provide a much better wave than using a wake shaper? Years ago I spent $5000 adding a VX platform to my rz2 2007 and it made a marginal difference to my wave at best. I don’t want to make that same mistake again. But If the GSA provides a huge improvement to the wave over a wake shaper than I will buy for sure.

        Agreed! I will also say your write-up and set-up is spot on - same results with our old '15 Z3. We ran 1k in lead most of the time... one time with 1400 at the reunion when conditions were perfect.

          that's a tricky question to answer and kinda subjective. somewhat depends on how sensitive you are to wave adjustments and differences, type of surfers you and your crew are, and your financial means.

          Is it better than a wake shaper, which is basically a manual gated wave, I'd say yes. Gated and shaper waves have their benefits and drawbacks, though i think that's more related to hull shape than the gate or shaper itself. Is it several thousand dollars better? that depends on how much you value those little wave differences and disposable $. In all candor, for probably 80%+ of people they won't notice enough difference to think it's worth it UNLESS you are only running stock water ballast with taps 3. in that case, absolutely worth it and even the casual surfer will notice and progress more easily. it's also subjective based on your own personal financial situation. if you spend enough time behind enough boats and to you have the means, absolutely i think it's worth it. is it more convenient than a manual shaper? yep, that's also a no brainer.

          so, not an easy answer and you'll have to form your own opinions on the value you place on each of those factors noted above to ultimately determine if it's worth it for you.

            Thanks for the well though out response. Of course you are correct. I just wish a bunch of people came on here and said “game changer” “‘no brainer” “it’s like a new boat” “don’t think twice just do it”.

            I think my wave is pretty epic with thousands of pounds of ballast and a suck gate but I always want to Upgrade to get better, faster, easier without buying a new boat.

              It is a game changer. I have 200 hrs of my rzx3 are with GSA tabs and the wave is much better. More traditional shape vs the very tige specific wave traditionally found.
              3 other friends of mine all went GSA as well and they all have amazing things to say.
              GSA on a rzx3 is better with lots of improvement but GSA on a Z3 is down right mind blowing on what it can do. In simple terms the system is idiot proof.

                I'm super excited for our 2020 r23 to show up tomorrow and to compare vs our old old 22ve and old z3 with vx.

                we listed the z3 for the first season and then started messing around with a shaper from d&p last year. we liked the listed wave better but heard the gsa plates are night and day......

                  Is there one supplier of GSA? I am in Canada. Do you know how many hours it would take to install and what a reasonable price would be for installation if I took it to my local Marina to do the work?

                          The following pictures are GSA plates on a 2018 Z3. There are three people in the boat, stock ballast filled all around, going 11.2 mph, first surf outing with the GSA plates. Surf set to 3, taps set to 4.

                          Observations - the wave is solid and super easy to create. The wave is tall and the pocket extends further out starboard than with the taps plates. The wave had push further back and we found we could recover further back in the wave than in July - taps 3 surfs. One of our three crew- (a beginner learning to wakeboard also) learned to surf from this push the day of these pics.

                          The boat sits differently in the water as it pushes through at surf speed vs taps3. As the plate deploys at speed, the boat doesn't ratchet over and you adjust the steering to counter. It is less pronounced.

                          We are going to play with the pitch and roll next few days to see where that is now, and what adjustments do to the wave's length and pocket. A lot of fun and a solid wave for sure.

                          Thanks to Jason at Germaine for getting us set up. D7E2C8F9-C0C6-4C13-B53C-71645262FF26_1_105_c.jpeg26ADD3E9-4105-45B2-9F39-7AC39BF4F5D8_1_105_c.jpeg8D47FDAF-2298-4D34-AB2C-5FEC47E50493_1_105_c.jpeg

                            There are always pros and cons....what con does the GSA plate have other than initial cost?

                            My understanding is the GSA imparts more yaw on the boat and the increased yaw is what makes the wave better. So what are the downsides to running the boat with increased yaw? The only thing I can see is increased fuel burn.

                            Has anyone noticed increased fuel burn when adding GSA plates? If so, how much?
