100mph Hulls?

[C-Mac]

Hi all,

I want to build an extremely fast boat but not a rigger. What are my Hull options since I am new to FE. What are some good name brand hulls I can look into?

Thanks for all your help

100 mph? And new to FE?

The only "moderately priced" FE boat to officially approach 100 mph was a specially-built and reinforced Whiplash 21 running in P Sport Hydro class. There are a few European cats which have reached that speed, but they were large, high-end builds. A three-point hydro is your best bet.

There is plenty of power available to go that fast, the problem is keeping the hull on the water. All commercial hulls are designed for half of that speed and they develop too much lift going faster. Adding weight, changing the aoa of the sponsons/hull and reducing lift are requirements, as is a strong hull. Crashing at even 80 mph will destroy most boats....this is not a project for a new FE boater.

A rigger is designed for speed IMO. You can put your batt packs up front or even weights to reduce lift at higher speeds. But your not interested in riggers....so the next best choice for me would be a cat.

As a relative 'newbie' to FE myself, I wouldn't recommend that you try 100mph at this stage. I worked my way towards my first 60mph+ boat and this took a lot of time, money and understanding. Going skyward at these speeds can really hurt your pocket and you don't want to be doing it on your first time out. Run the lower speeds first and talk to the people who are running higher speeds. you'll need to glean them of all of their experience to even get started on such a project. Just getting the right set-up will be a challenge. If you get that wrong, you'll be frying your electronics way before you even get a chance to reach 100mph.

I'm running low 50's in my EKOS now but want something faster. I have a few friends into boating that have boats that push 60+mph.I always research before I buy but was just hopeing to get a head start on hull direction. I like cats but are not to familiar with hull brands other than Aeromarine. :)

Budget?

Same question.

My advice (as a newbie) would be to trawl through this forum and find a thread where someone has followed their complete build. Get the same hull, set-up, props etc, so that you are not trying to do something 'new'. Then at least you are halving the amount of mistakes you could make. Then, when you are building, contact the person who posted the thread and learn from them; what they would've done differently.

My first fast FE was a Triton from Toysport. I asked for a set-up directly from the guy who built the hull; Joseph Toth.

Maybe this is an option for you; (if your wallet is deep enough)

Hanspeter is a member on this forum and is the builder of these hulls. If you want to go really fast, then this is the place for you....

G-freak should be able to get you there, try the stage infinity!

Seriously, taking the rigger out of the question, leaves you with a more scale hydro or Cat.

Prebuilt hulls will probably limit you to a cat.

100mph is going to take lots of energy, which means a good battery that will have some mass to it. That is going to require a strong hull or it will rip your boat to shreds when you blow off the water. You are talking some bucks, that is for sure.

Good luck and sorry for the poor taste of the first line......

Interesting choice, but IMO it is a poor recommendation to give to someone. Most commercial cat hulls have too much lift and won't stay on the water. The few German boaters who exceed 100 mph in cats do so with boats costing many 1000s of euros.

My SAW P-cat record has stood for years because the hull was custom-designed without compromise for maximum speed. I have not been able to exceed my own record with any commercial hull, even with LiPo cells. It is far more difficult than it appears to the layman. That's why so few compete in SAW events.

If someone wants to take a commercial hull to 100 mph, it should be a 3-point hydro. Far, far easier to do than with any cat, but still not easy to do. And it is not for a beginner.

First of, welcome now the hard part...as Doby mentioned what $$$....the speed you are looking at is a missile...whether you are new to FE or not has no bearing on your question.... what gas/electric hulls have you run and at what speeds and how long have you been doing this sport? ...Why 100mph, as that is a professional ambition.... The hard part in racing is turning the corner in race/choppy water and again what is your budget for a custom hull and other components.

There's a very nice gentleman and his son, a Berkely Physics grad, who have been running a large Aeromarine hydro at Legg Lake. The boat took months of intricate labor to reinforce and prepare it for high speed runs. It was a 12S boat with top of the line components from Germany and probably was in the realm of $ 3500 - $ 4000 dollars to put in the water. Last week his son was driving and clocked 82 mph on the gun. Then it lurched, stuffed, and came up on fire. The flames were over three feet tall. Nothing was left. I've been to many SAW's where the 80+mph boats , piloted by racers with years and years of experience , regularly leave the water at speed with much damage - that is the ones that don't disinegrate and sink. If you're ready to jump in, be sure to have a big bank account, a fire extinguisher, and scuba gear

I agree with you. I chased crazy speed for a long time and when you hit a certain number you just want to better it and it gets crazy expensive. I burned up more ESCs and batteries than you can amagine. My best mph was 102 with my Hydro and i could not touch it from that point on and really spent money and time to beat it.I was so frustrated I actually quit boating for a month and sold it all but started jonesing and had to jump back in . Now i will stay around 70-80mph and injoy boating for a change.
