Stern thrusters are absolutely amazing!! People slow down when they pass our dock!
Germaine Marine = the VIP dealership! A few weeks ago, we took ownership of our first wakesurf boat! A 2021 Supra SL 450!! Just wanted to thank our salesman, Chris Jackson and Germaine’s big kahuna, Jason Robertson for the VIP treatment. Jason flew out to Havasu, spent a ½ day with me on the lake showing me the operations of the Supra, then even took me out to lunch! Also, a shout-out to Josh, the Havasu service tech, who went above and beyond in getting our SL set up for the lake. AMAZING!Read More
This was our second Supra and we couldn't be happier. Amazing brand, amazing tech. Stern Thrusters, Underwater Lighting, we love everything about our SL550!Read More
We upgraded to a 2021 Supra SL from a Moomba. We loved our Moomba and had great family time and made great memories on it. Yet, our Supra just blows us away each time we take it out. Amazing Wake with a ton of push on both sides. Fit and finish = A1. It rides/cruises amazingly. Giant bimini. The driver seat is just WOW. Flip-up seats are also a HUGE plus.Read More
I live in Bend Oregon and the Dealer is in Portland, 3 hrs away. But our experience was so great, the sales staff and service was above and beyond. I would buy another one in a minute! Total pros. The boat.a SL 400 is so awesome.Read More
My new SL has so many amazing options and features throughout the entire boat and the majority of them were STANDARD which is nice compared to the other brands I looked at where it seemed almost every single option was an "upgrade". I really love the crazy loud factory stereo. I only had to add tower speakers to my build. My other two favorites are the power tower and chill tech vinyl. Autowake is a given with Supra that you can't help but love as well! Thank you SUPRA BOATS!!!Read More
2021 Supra is one of the most beautiful boats have previously owned a Master Craft it was a great boat but Supra is far superior.
Great boat fit and finish was on point. Compared to every other boat in the same class the Supra was leaps and bounds beyond its competitors.
These new Supra's are amazing, the storage space is awesome with the sub floor ballast, and the Chill tech is super comfy. We love the color combos available! We would definitely return to Supra when we purchase a new boat.Read More
So far very happy with my 2021 450SL been in the water four times this season already.
The boat was amazing in every way they thought of everything and engineered it to be functional and long lasting. I bought it for the looks and it’s wave, the solidness of the build was the part that I was blown away with. I bought the boat without ever seeing one and my salesperson Mike LaMacchia was there every step of the way recommending things I didn’t even consider to make it the boat I wanted. Then he was there to execute on the details that we discussed, the process was flawless.Read More
This SL 450 is the third new Supra I have purchased in the last 10 years. Each boat has improved remarkably. This boat is amazing ! Would not consider any other boat.Read More
Awesome service, Knowledgeable staff, and friendly and inviting atmosphere. They make you feel like you are part of their family.
We Love our new SA450!! It has the extra space we were looking for. It makes a great wake for surfing and yet can be toned down enough to ski behind. this boat should give our family years of fun on the water.Read More
Top notch from bow to stern
I have bought a few bought a few boats and this one has by far been my mist researched and fulfilling buy yet!! Thanks to the folks at The Slalom shop for making this dream a reality. Jeremy DeckertRead More
Between the salesman and dealer this has been a great purchasing experience and an awesome product from what I can tell. I haven’t had a chance to get it on the water due to weather and timing of year but we plan on spending many great hours on the water in the future. Will was our salesman and he was very knowledgeable about the product vs other competitors and definitely made us feel comfortable with our upgrade from our old Supra 24ssv to the SL400.Read More
The comfort and quality of our Supra SL400 just can’t be beat.
Off the chart customer service and experience. Fit and finish superb. Wave is unbelievable. Auto wake technology is superb.
This Boat is amazing. The wake is top of the line. The fit and function is better than other boats I have been on. Everyone wants to drive it and everyone wants to try to surf on the huge easy to setup wave. It’s fun for the family and for an adult day out. I would definitely recommend this boat brand to anyone that has an itch to do sports on the water or go out and just listen to music.Read More
