Radio Controlled Speed Sailing, Seriously Amazing

R/C Speed Sailing Project

AC 9.8 - 100% Awesome

We are planned the biggest, fastest, and most exciting radio controlled sailboat in history. Maybe too big: This massive catamaran is over 9'10" long.

The AC 9.8 is a R/C catamaran: twin knifelike hulls, each 9 feet 10 inches long, but only a few inches wide.

Connecting the two hulls are tube crossbeams. Topping it all off are two full sized windsurfing sails.

Our job is to discover and push the limits of this new boat. People are fascinated with speed, pushing themselves ever faster on water. For Millennia the quest for speed was among the main driving forces of progress. Speed sailing all grew and advanced fueled by our insatiable appetite for moving faster, for covering greater distances in less time.

We are confident that our innovative design concept will result in a super-fast catamaran and establish a string of speed records.

We need supporters, both big and small, to support the construction of worlds fastest R/C Speed Sailing that may be the first ever R/C to reach really high speeds. We know that you are going to love to see our videos of record-breaking sailing and we can't wait for you to see it!


Right now we are testing two smaller Sailboats, modifying it to match the larger future boat. Now we know what we need to do, to move forward. Both boats have 10 foot tall masts.

The challenge:

The challenge is to build the fastest Radio Controlled Model Sailboat.

With light as possible hulls and with the largest sails possible, creates problems. With the push for speed comes the risk of capsizing the boat and damaging it. We need to find the perfect balance.

We will set the world Record Radio Controlled Sailboats. Years ago we had the French Boat designer Jean Margail design a much larger 3 meter sailboat for us. But we did no have the time or funds to build the boat. Would you like help us set the Gunnises world record? The world's first, game-changing new R/C Speed Sailing sailboat R/C Speed Sailing, we need your help.

What is the 3 meter boat?

Imagine the world's largest and fastest R/C muiltihull sailboat 3 meter long, radically designed from the ground up to be extremely easy to build, modify, and sail. 3m = 9 feet 10 inches, that's almost ten feet long!

The ten foot long 3 Meter Sailboat will have two hulls, two sets of sails, a set of sails above each hull. It will be light as possible and with the largest sails possible.

The Science of Speed

Hull design

Wave making resistance depends dramatically on the general proportions and shape of the hull: modern displacement designs that can easily exceed their 'hull speed' without planing include hulls with very fine ends, long hulls with relatively narrow beam and wave-piercing designs. These benefits are commonly realised by some canoes, competitive rowing boats, catamarans, fast ferries and other commercial, fishing and military vessels based on such concepts.

Vessel weight is also a critical consideration: it affects wave amplitude, and therefore the energy transferred to the wave for a given hull length.

Heavy boats with hulls designed for planing generally cannot exceed hull speed without planing. Light, narrow boats with hulls not designed for planing can easily exceed hull speed without planing; indeed, the unfavorable amplification of wave height due to constructive interference diminishes as speed increases above hull speed. For example, world-class racing kayaks can exceed hull speed by more than 100%,even though they do not plane. Semi-displacement hulls are usually intermediate between these two extremes.

Designs that help increase speed, reduce resistance.

  • Wave-piercing designs, very fine ends that cut through the water, long narrow
  • Multihulls, Catamaran Boats
  • A planing hull, gets on top of the water
  • Better Sail designs, shape, larger,
  • Wing masts, reduce drag
  • Light weight hull and materials
  • Winged Keels
  • Movable ballast
  • Lightest matterials and light weight hulls and incredible large sail area

The Crew

Gerald Hall

Gerald Hall is skilled in electrical controls, and has built many R/C model sailboats through the years. Each time he builds it's more and more challenging projects. He is also an artist, painter sculptor, wood carver furniture maker, and custom home builder.

Tyler Laffoon

Tyler is a electrician, mountain biker, he loves water sports, jet skiing, building off road vehicles and trucks. He is looking forward to this boat build.

Kory Harreschou

Kory is a college student, working as a waiter to support his schooling. He is wanting a willing to see this project succeed.


Our gratitude goes out to all who have contributed to the project so far. All monies received will only be utilized to advance our speed sailing project. As well as making a world class speed sailing boat, we are making the designs an open source to all. We are sharing our boat building project with boat builders around the world.

Thinking about building your own boat? Stay tuned we will have plans posted on the site. We will be video the boat-building project from start to finish. Use the link below, to donation amount you can spare. these donations will help test our prototype boat before we start our full blown kickstarter project.

World R/C Speed Records

Speed Measurement

For uniformity all runs are measured by a GPS Phone App mounting on the boat. ALL runs be recorded on video from start to finish.

The device we will use is a smart phone with the App for android and Iphone, Gspeedo. At the start of the run, the max speed must be zeroed, then take the boat out and return and record the maximum speed shown on the app.

Besides the GPS based tacho GSpeedo shows:

  • current speed
  • average speed
  • maximum speed
  • driven distance
  • acceleration/breaking G-Forces
  • speed history graph
  • total time
  • moving time
  • sensor or GPS-based compass
