2007 SV211 Refresh

[TechBeer]

FMSKI, amazing project. As anyone knows a stock SV211 is NOT a good slalom boat. My 86 SN2001 was way better. But you couldn't surf behind it. Great work.

BTW, when your gauges fail I'm your guy... :-)

[FMSKI]

Good to know about the gauges, thanks.

We skied a TSC1 yesterday, and there was sizeable wake at 28off, but because the boat is small (feels like a fairground amusement ride boat) lots of terrain to cut. He has the back seat in etc. My 2001 I added trim tabs - v/narrow boat with that motor-too-heavy for the size planing angle.

No way around it, trying to lift weight comes at a cost of disturbance, so my process of weight reduction is best for slaloming. At this stage I couldn't go back to a 196, too small a boat. The 200 was good, you can ski that with 4 people aboard, but it doesn't surf either.

This is as close to my ideal boat as I can get. Eg Im not sure a 200V is worth it, doesn't have the ballast carrying capacity, and the GS20 or 22 is too big @ 4700lbs +. I did see the Malibu VTX has a center pylon but it's a beast and not a Nautique

7am had the best slalom set ever! 32 off wake is absolute butter.

Then loaded up the ballast (bow, lockers and some extra since just two surfers today). Thought might as well move the ski plyon back for an extended tow point, as I don't have the tower on. Couple of coffees. Dropped the FMSS plate on the starboard side and baam what a wake!

Wild that this was actually doable. Great performance in both modes. FM Ski 'n Surf concept complete!

Looks good. What's the boat speed for the slalom wake?

[FMSKI]

The speed in that shot is 32.9, I dropped it a bit today cause my ski bud had a hard day of MTB.
But on that note, the plates down make for better slow speed wakes. I ran full down at 30mph and my neighbor skied 28 looked good.

At 34mph fully deployed created the ruckus, and it's best to pull them up. I can see the FMSS plastic bases directing enough flow to trim the wake as shown.

It's quite subtle in that when the wake is too much (hollow or rooster) it is hard to execute the proper balance between pull and turn. If the wake is flat to a critical level, then proper slalom rhythm can be achieved. We are at the threshold now, where you can ski a good set.

[FMSKI]

Had the pylon system apart for sealing the yellow cedar. Added some clearance to make it easier to move, since that was not the original plan, but for surfing without a tower is a real benefit. So ski, surf and use the short stubby for tubing. I have one modified u-bolt on the rear mid-mount. The rear has a push-in base block and the CNC bezel fit at the top, which is all pretty cool, nice snug fit.

Building the boat Nautique should have built!

[FMSKI]

Skied the TSC1 boat (GT40, classic Perfect Pass) for last 3 days. Back to the S'nSV211 today. The 211 pull is more solid, and wake awesome at 32off. There is a bit more trough for sure but no rooster at the line length. The strength of the pull alone, is worth using the 211 between the two. For the 2025 Mastercraft prostar, they also mounted the ski pylon to the hull structure for a better connection. It does make a difference. I have GPS PP speed control too.

Unfortunately, if adhering to marine engineering standard, Nautique could not build this specification and have it certify. I add 2500lb of ballast, the moveable pylon/plates are a user-risk element, the swim platform is not lifetime. It needs to be the proverbial Swiss Army knife of boats.

Safe ballast carry is the reason the model lineup are essentially big barges, which kinda foregoes the ability for proper slalom skiing.

Edit - sweet skiing... 67yo doc before heading to ops.

This is G country with a wave this sweet, Found the banger oreo brownie recipe and let it simmmer. 10.3 mph all push 'n pop and no leftovers.
FMSS plate is key as it works the transom corner (pull and some lift). Add in the H3X shaper further up the hull in front of the vent and on the crease line. About 3300# of ballast.

Made a lot of progress and learned a lot about "single boat theory" this season. Geez it'd be cool to have a ski and a surf boat but we are pretty much at a) tournament ski performance 28-35off and b) consistently great surf formula. I keep looking at surf boats ('23 S23 $150K = good deal) but managing two boats is a real headache for me.

The props make a difference on how the transom sits: 381 ski, 645 both, 1433 Surf. Just have to figure out how to change in the water . Which I have done once before.
The pylon was a game changer for skiing. FMSS surf plates I'm going to amp up the deployment as they produced the best wave under full ballast. I am going to add more lift and side dig by routing the paths. .
This boat does way better if listed so the V bottom is flat on the surf side.
I'm going to see if I can get the surfboard shaper to make me a platform at like 15 lbs. I could also reduced the weight of the engine cover.
Simple equation is Weight out = ski, weight in = surf.
Had a great ski set to close out the year, a few days after surfing... not a bad wave at all:

This has been fun to watch. Dr. Frankenstein meets tow boat.

Remind me (sorry if I didn't see in thread above)....how much weight are you adding to surf?

[FMSKI]

I rode a 6' short board shaped by Stefan at Aftanas in Tofino with only 800lbs or so in the starboard locker. I surfed the way out, had my buddy do a turn-around (boat did a loop) and the way back to dock, without losing the wave - felt like I was on some sort of hydrofoil. In fact I was at his shop in Tofino today talking boards. He was able to ID the issues in the Ronix Atlantik I just got, and why I was not liking that. Stefan is going to make me a wakesurf board after he talks to his buddy, who surfs ocean & wake and did a design. .. next season!

What I figure now is a silky, well-shaped board, on a properly settled/tuned boat, is better than a whack of ballast with a bad board and hull attitude.

In that video above we have 600 bow, 400 belly, 400 floor, 1000 starboard, 700 port and 400 on the step thru : approx 3500 total. The rooster plume is the 1433 prop and the water is cold, which makes a difference - it's harder to surf in <60 Deg.
