Swell
 

Does anyone know if it can be retrofitted onto my 2013 SA?

Nope. Swell is only tailored to the 2014 SA & SC models. I believe it has to do with something directly related to software for boat's electronic/computer systems... and that they want you to buy to upgrade to a '14 model too.

^^ Bingo. Software has been updated to integrate it with swell, and I'm pretty sure the hull has been beefed up where the system attaches too.

Took a page right out of Malibu's Surfgate book. Nope sorry not backwards compatible, please buy a new boat. From what I saw it worked as the local Malibu dealer had a crap load of used 12's that people traded on Surfgate boats. Nautique was only backwards compatible for 1 year due to software.

10-4. Thanks. We are rookies so it won't matter initially. Moving up from a small direct drive that wasn't surf friendly so this'll be better.

Seems like you could buy the parts and do it manual operation, but good point about the hull. I actually thought some 13's had it.

LOL, hull upgrades. Malibu tried to claim the same thing but no one has observed any difference in the '12 and '13 hulls. I'm sure there is no difference in the Supra hulls either. It's all about selling new boats.

there is a difference in the hull..be sure to stop by a local dealer and take a look.

Whats the difference? So Supra made a brand new boat for a mid year 2013 release and then changed the brand new boat they had only been making for a few months to then add the swell to it? I'm no expert, but that doesn't make sense to me. I'm sure its a safe bet to assume the Swell was in the works long before the SA's were released.

After testing it was decided that extra lamination was needed so they added a 4" x 24" piece of trevera for screw retention.

So basically what you are saying is the hull on the Supra was to thin for the trim tab on the side (swell) to be screwed in to therefore you increase the hull thickness not shape so the screw does not strip out? Just want to make sure I am hearing this right.

Looking at how the swell operates it would seem that it puts an enormous amount of stress on the transom when it is full deployed down. the whole purpose of reversing the actuator design was to get more rang of motion. I can't see any transom that could probably take that stress that was designed specifically for the SWELL system holding up. They design them for their intended load and before the swell the intended load was light so they reinforced it to make it strong for the higher load the swell will cause. I don't see the problem here.

Couldn't of said it better myself

Well the approach worked and I traded in my 13 SA for a 14.

its a simple system just fancy trim tabs. It might not integrate with the computer but im sure you could do it as a stand alone system.
