Trayson's DIY "Supra Surf System" (SSS) modeled after the NSS

I was thinking that the decrease in speed would heighten the wave out and give me more push. If speeding up lengthens the wave, logic told me that slowing down would heighten it...

To a point it does the above.

When you slow down, you do get more push on the Transition, or front of the wave coming right out the back of the boat. If you slow down too much though you lose both push and length because you are not <eating> enough water under the boat. It just plows through it.

Most boats like 10mph, and then you adjust around .5 up. We tend to run at 11 and when you ran with us, Goofy was 10.5 and Reg was actually 11.5. This is due to weight in the boat.

Surfing is similar to wake boarding when weighting, the more weight, the faster you need to go to get it clean.

The other effect of speed when surfing is, Running a lot of weight at 10 you get a HUGE transition and TONS of power on the front of the wave, so you speed up to allow the boat to plane a little more and thus flattening out the transition section and this in turn pushes the power in the wave farther back.

It will also make the pocket longer in length, but shorter in height.

makes sense. lots to play with an experiment with, that's for sure.

So, I relocated my fuel breather and drained the 22 gallons out of my tank and changed my fuel filter. Filled with new gas and once the bad gas was out of the lines, we were good to go.


Again, we filled the 370 tube sack under the rear seat and had the pair of 750's on either side of the doghouse. The boat sat mostly flat with a slight (couple inches) list to the port. We fine tuned with the placement of the rear seat spotter.

Bottom line is that I won't go back to listing. Today I had all the push I needed. I was riding my Ronix Caption 5'8 because just as we were leaving the dock my Koal illumanati dropped and cracked the tip of one of the tails and needs some fiberglass repair love.

I was able to ride way further back in the pocket. I was able to carve and shred the wave just fine. We were able to drop our surf speed from being in the 10 to 11 range down to being between 8.3 and 9 mph. The boat isn't working as hard and isn't slammed as much. We had some big rollers go by us and took no water over the stern. We have zero issues with dunking the nose either. With the ballast full, we can easily chill out and have lunch and be COMFORTABLE in the boat. Also, we can drive sitting down. It was bad enough before that I either sat on the top of the backrest of the chair, or just stood up to drive. Swapping from regular to goofy was literally a 10 to 20 second changeover.

Since we're not having to double stack bags, we were able to get 2 ballast pumps going at the same time to fill the 750's while my reversible impeller pump took care of the tube sack under the rear seat.

There is no adverse handling of the boat when going back to get the rider. If you turn against the blade, you kind of notice it but honestly it's not even something you notice unless you're looking for it. The boat comes out of the hole just fine and the wave is clean as soon as Perfect pass has you at surf speed.

We'll get some pics posted up but I would do this again in a heartbeat. Some of you might poo-poo what I've done, but the overall enjoyability of our boat just took a huge leap. I'm going to chalk this up as a success.

None of the pics are on my phone, so I only have a quick mirror shot.

I think you have used some great innovation and took a risk that not many would with your design, I for one would love to try surfing behind your boat this summer. I got plenty of time off so I don't mind the drive LOL.

Let's do it! I'm off all next week. But I don't think your sabatical starts by then.

Here are a couple better pics of the wave. Now, is it a wave that tops a $40k to $100k vdrive? Probably not. But for a 1992 direct drive, I'm pretty happy.



This is only the 2nd time I've rode goofy. I'm a newb at it. And obviously regular is better on my boat. But FWIW, here's the goofy wave.
