I'm sure Tuff can squeeze a few more MPH out of there!

I wonder if they've tried a different prop?

Mark mentioned they could run it in 1350 mode but would probably want to make some changes, primarily the propeller and possibly a hatch or canopy for aerodynamics. In fact, there was consideration of using a hatch and removing the seats to optimize the run but they decide to run it as is.

Impressive run no doubt. I enjoy wave 2 waves content. Any boating content is good content.

The guy wiho was racing the dual outboard lavey 2750 is selling that and buying a tough 34 to race. We are all gonna find out together if it can handle rough water because revelation racing doesn't play.

A production boat top speed should be considered differently than a race purposed boat speed.

To call that Tuff a 'Production Boat' is a stretch, just like almost all true high performance boats, other than the hull everything is unique, there are no two alike. That being said, the hull itself might even have post mold bottom work done to it as well. Most boats running those speeds do as it's very hard to get the ideal shape right out of the mold due to shrinkage and sag.

Throwing a rear bench in an Ausie ski race boat make it a production boat? there is no distinct difference between the two in terms of manufacturing or rigging.

148 is hauling the mail, no doubt, that is absolutely fucking hauling ass, and very impressive on its own. But it's not the only one capable by any stretch.

Other than the BAD boats you posted Iā€™m not seeing anyone showing 150+ in a single v bottom.

A lot of ā€œtheoreticalā€ top speeds out of the ski race boats. Has anyone ever posted 150 in a 21-24 ski race boat?

Itā€™s one thing to be capable vs doing it lol.

I'm sure they have. I have seen the video of 139 on GPS with 2 skiers, and the boat is dead steady. 10mph when you are talking about ditching all that drag is not some giant stretch of the imagination.

What do you think happens to the top speed of a Tuff when you have 2 200lbs Skiers on the line?

Like i said it's still damn fast, very impressive.

From what I remember thatā€™s what they told me when I asked them. Those boats ran fast and loose. Didnā€™t get pics of them running though. I like how they are using a wrench for their in/out on the v-drive View attachment 1288460 View attachment 1288461 View attachment 1288462
The class (Australian) is 6L (litre) These engines are the Dodge Cup motors 358ci 9000+ RPM screamers. Ade Bloomfield brought 4 over in hopes us Americans would buy into the class, if more people would have jumped on board, they were going to bring a mold over as well. It didn't take off, and the boats went back to Australia. The engines also run a closed water system, standard water pump. Water from the river, goes through a heat exchanger and exits. They are in the 130-135 maybe a little more mph range.

I think an Outerlimits SV29 with a TCM 1200QR and #6 could give it a run for the money.

The SV29 goes 100 with a Merc 600. Add another 600 and what would it do?
Not a chance. That hull just wouldn't be able to.

The Tuff 28 and 34 is considerably faster than an OL SV29.

There was a blue carbon Tuff 28 with a stock Merc 860 that runs 137 MPH and ran 125 at the Ozarks shootout, which is a short run.

I love the SV 29, but that hull is not gonna do it

It's a great discussion. Thanks for the positive feedback on the video. I'm definitely not a videographer.

I've been around a long time and just haven't seen a V hull pleasure boat with a single 1100 remotely close to the Tuff 34.

How about a 22' Schiada V-Drive? Here's a screen shot of it running half throttle......full interior...no canopy. It's probably capable of 160+.

This was a screen shot I took, it actually hit 142 at one point in this video, but it's since been taken down and private.

I appreciate the info regarding "tuning" a hull design. I don't know anything about the Tuff, and just assumed it was a commercially available product. Your wide knowledge of the auto, boating, and engineering world is always helpful and educational.

Sure. Is there a video or any documentation of it exceeding 148 MPH? Would be hard to believe with a hull like that.

There is a video on the Schiada Facebook page of it on the Parker strip at 134mph as I recall and it wasn't even breathing hard.

Schiada's do it all the time they just don't talk about it like them Hallett guys do. :)

How do the Tuff's turn at 110+? are they a heavily stepped bottom?

From what i know of them they are a very high quality hand built custom boat, very low volume.

Looks they aren't even a step bottom which is a good thing IMO for that size boat, probably turns pretty well at speed.

Hard to believe it could possibly go 7MPH faster?

:rolleyes:
Iā€™ve said it before, Iā€™ll say it again. I was told through a very reliable source that Alexiā€™s boat is capable of 150+mph.

I never understood trying to get big #'s out of a V. If you want to go fast get a cat.

Well no argument, the BAD boats are for sure BAD as this video shows ---- Vee bottom, check, got that, otherwise, not really in the same category as a Tuff. Yet really, that also shows just how fast that Tuff truly is.

It always amazes me how those boats roll on the keel and porpose slightly @ 150 mph+ and never seem to get outa shape and wad up. That is friggen crazy..
Ii always enjoy watching those guys race as well as the 6L boats. Driving 1 must be incredibly exhilerating.

I understand the small boats a little more. Bigger V's going for top speed I don't get.
I figured you of all people understand what it's like to push a brick down the road. ...just put a side oiler in it. :)

Because driving a v bottom is rewarding, a tunnel you just steer.

My Skater was the opposite of just steering. Trim a little too much and it would get flighty. Definitely a drivers boat.

I'm guessing since they used to run without a capsule, and now they do, somebody's waded one up on occasion. :(

In fact here's a very sad commentary on just this thing.

There is an entire race class down in Australia that they have had to limit to 135mph... While pulling 2 skiers. Go ahead and imagine someone caring enough to strong one out without the rules. 148 isn't enough. 158 isn't enough...
There's a significant difference between 135 and 150. The aerodynamics alone are significant part. I'd love to see one of them run that fast, haven't seen it though.

The Tuff is 36 feet overall, stock 1100, full interior pleasure boat. It's hard to find a purpose built race boat of any kind with 1100 HP that's as fast.

Kinda like having a big dick. There's only so much you can do with it until you learn how and where to use it to it's full potential.
Not bragging but... I'm on the gifted side of that philosophy but still don't understand the immense sacrifices to just reach a number for personal satisfaction. Again, the strive to being #1 I totally understand, but it has to be in reason?

At this point Iā€™m kinda wondering if this is a one trick pony. Can the Tuff even handle chop and above (ocean conditions) with any decency or is it a straight line missile only on glass?

I think Iā€™d prefer an all around performer. How often would anyone spend time at the top number and in the mean time get beat to shit if conditions arenā€™t glass?

Howā€™s this handle big water?

We could make a rough water wave killer Vee bottom but why? There are lots of them out there, so we seem to be in the ā€œworlds fastest in categoryā€ game of Vee bottoms.

Quite good, with a sharp entry and reasonably deep deadrise. Some 28s have a ballast, making them quite good in some chop, the narrow beam helps too.
The 25 is very good in a chop, especially compared to some others and considering it's easily the fastest in that size range.
A Chaudron 25 is among the best in that size in rough water, but not as fast, although still fast.

Again, always a trade-off. Many 24 degree heavy offshore boats aren't that fast power for power, don't handle that well, but can run well in rough water.

Like Ace Ventura, "I'm a lover of all animals." (Boats)
