It is the same hull as an Avalanche. Great wakeboard wake if you dial it in right and one of the best surf waves for the price you can possibly get. Definitely a solid boat and that price isn't bad at all on it.

Couple things I will throw in here on the Opti-V hull vs. the original Ri hull - this would also include the FS and SV hulls as well: The surf wave is pretty similar, just easier to dial in. The wave is not a big reason to go with the Opti-V hull compared to a 16/17 Ri237. The benefits of the Opti-V hull compared to a 16/17 Ri are the following: Wakeboard wake - if you wakeboard this one is HUUUUGE. The old Ri hull is decent, the Opti-V hull dishes out one of the best wakeboard wakes at any ability level on the planet. Fuel economy - A definite improvement Power - Not a huge impact, but there is a noticeable improvement in hole shot on the Opti-V hull Driveability - The new hull drives and handles significantly better at both higher and lower speeds. Ski Wake - Once again, if you ski, the ski wake is noticeably improved. Things that are just as good on the 16/17 Ri237 compared to the Opti-V Hull: Rough Water Ride Hydrofoiling Tubing Partying Barefooting - both are equally terrible for barefooting Pissing off fishermen

The question of a 2018 Ri237 vs. a 2016-2017 is one we have gotten a fair bit. The 50% improvement in fuel efficiency that the factory is stating I believe is a 2018 Ri237 vs. a 2016 Ri237. In 2017 they changed the shaft angle which improved the fuel efficiency by probably 25% (because of the new propeller options) and then another 25% improvement with Opti-V. If the current Ri237 / Ri257 has Opti-V 2.0 then the Ri217 (all years) is basically Opti-V 1.5. The 217 is more fuel efficient than previous Ri237 hulls though not quite as efficient as the 2018 Opti-V hull on the Ri237 and Ri257. Though we haven't hooked a Diacom up to a 2016 or 2017 Ri237 I can state from personal experience at Surf Events that it is still definitely more fuel efficient than a Nautique G series or Malibu MXZ. When we ran a 2016 Ri237 at the Utah Surf Fest it was the only boat that could get through the whole day on a single tank of fuel and all of the other boats had to refuel about 2/3 through the day despite having a similar size gas tank.

Part 2 of our video series comparing a Centurion Ri25, Nautique G23 and Malibu 24MXZ - this time we hit on fuel economy for wakeboarding, 0-23mph speed when loaded and the difference between a Centurion Ri257 w/ a H6 and a Nautique G23 w/ XR7 when it comes to power. Hope you fellas enjoy! http://www.mmwatersports.com/boat-performance/centurion-vs-malibu-vs-nautique-power-and-performance/

We got a chance to take out a Centurion Ri257, Nautique G23 and Malibu 24MXZ so we decided to hook a diagnostic computer up to them and see how they compare when it comes to fuel consumption. Does the Opti-V hull live up to the hype? http://www.mmwatersports.com/boat-performance/centurion-vs-malibu-vs-nautique-wakesurf-fuel-economy/

I can give some feedback on this: It is a bit harder to keep clean as it shows dirt and such more than grey and quite a bit more than Whiskey Barrel / Toffee. If you keep shoes out of the boat and keep your boat really clean it isn't too bad, but it is harder to maintain than the other colors. That said, it doesn't get hot and it looks really good.

The Fi is impacted less by shallow water than any boats I have ever been in - definitely impacted less than a SV and slightly less than a Ri. If you use Quicksurf that does change things though - a boat that is listed in shallow water will perform better than one using Quicksurf. I am not saying that the FS will surf better than the Ri in shallow water, I am just saying it will be impacted less than a Ri. The Ri still puts out the best wave of any boat I have been on - even in shallow water, but the impact on it is a bit more than what we see on a FS44. I have heard that using a surf system attachment like a Wakesurf Shaper creates a better wave in shallow water, but I haven't tested it personally. Typically these systems don't work nearly as well as Quicksurf on Ri and FS models, but I have heard they make a big difference in shallow water (13 feet and under). It is also important to keep in mind that when it comes to shallow water the changes are exponential, meaning you will notice a much bigger difference between 10 feet and 12 feet vs. 12 feet and 14 feet. The difference between 15 and 20 is barely noticeable where the difference between 9 and 10 is significant.

Any of the Ri series, FS Series, etc. will surf great in over 15 feet and ideally over 20 feet. They will surf decently as low as 10 feet of depth, however you need to slow the boat down. As an example, you can get a respectable surf wave on a Ri257 w/ stock ballast in 10 feet of depth but you are going around 9.8MPH. Typically you would surf on a Ri257 at 11.2mph. At 8 feet the waves become essentially impossible to clean up. Any decrease in depth below 20 feet needs to be met with a decrease in speed. Your wave will be shorter, but you can keep the power and mass.

The surf wave is improved, though not dramatically. The biggest difference is the wave is easier to set up and doesn't require as much tweaking to be absolutely insane. If you are comparing a totally dialed 17 to an 18 you will notice a wave with a bit of an increase in power and length but overall not a huge difference.

Ski Speed - 34 mph Wakeboard Speed - 22.5 mph Surf Speed - 11.0 mph The Fi23 and Ri237 has a clean beginner wakeboard wake at 18mph w/ zero ballast (great shape too!). If you add more ballast you just need to speed up a bit to clean it up but with Ramfill full the wakeboard wake is clean at 20-21mph, maybe slower - I haven't played around with the speed when the boat is loaded up.

We have a demo 2017 Ri217 that is white and silver - new, full warranty. Message me if you are interested in more info, pricing, etc.

Hey guys, Here is a video we put together showing wakeboarding, wakesurfing and water skiing behind the same boat in one take with no edits, cuts or anything else. If you want to see what the stock setup of the new 2018 boats looks like for all 3 sports this will give you a solid idea. Hope you like it! http://www.mmwatersports.com/boat-performance/surf-ski-wakeboard-one-boat-5-minutes/

At the Rocky Mountain Wakesurf Open we were running a Ri257 w/ 5800 lbs. of ballast and 6-8 passengers. After pulling over 60 riders with 10 hours of straight surfing (10 min break every couple hours but otherwise NON-STOP surfing) the Ri257 burned just under 1/2 a tank of fuel. Seriously...

The next gen Quick Surf is on Centurion models for 2018 - both Ri and Fi.

Hey Guys, Just recently posted up a new blog post detailing the most important changes on the 2018 Centurion lineup. Hopefully this answers some questions and gives some helpful information: http://www.mmwatersports.com/uncategorized/whats-new-for-2018/ Enjoy!
