Frequently Asked Questions

Can I sail the boat without the lifting foils?

Yes, you can, simply lift the two lifting boards and enjoy the traditional way of sailing.

How do I launch the boat?

The string controlled lifting boards are in the up position, rudder and daggerboard are raised. Launching from a slipway is as simple as a ‘normal’ sailing dinghy. Store your trolley, push the boat away and jump in. The lifting boards stay clear from the boom so no risk for damage.  After moving away from the slipway, the rudder and daggerboard can be pushed down. When you are comfortable, simply deploy the lifting boards and go!

And returning to the slipway?

Lowering the sail is easy, simply release the halyard and lower it. No nasty high speed, uncontrollable and potentially dangerous returns to the slipway anymore.  Landing with raised foils is the same as in any other conventional dinghy. Every sailor has touched the bottom with the centerboard. The Flo1’s daggerboard is equipped with a safety cleat and pops up when this might happen. No hassle.

A light boat, fragile as well?

The boat is built using sandwich epoxy laminate with carbon reinforcements. The boat is engineered with durability in mind. Carbon is put in the high load areas where it helps create a durably stiff but light weight structure.

Why a stayed rig, isn’t that complicated?

Well… weight is the main answer. The stayed rig is much lighter and easier to handle than an unstayed configuration.  We tested an unstayed mast on the 2nd generation prototype, but this one behaves much better. The simple spreader less rig with additional ‘lowers’ is easy to setup and to tune. Dropping the sail before landing on the slipway is made much easier without a pocket luff. The mast can be split in two equal length pieces for storage and transport.

The foils

A lot of carbon is processed in the critical foil areas.  The carbon fibers are placed where you really need them. This creates a stiff and safe foil, while at the same time the flex in the foil tips create a damping effect for a comfortable ride. Best of both worlds!

What about sailors weights?

The Flo1 is sailed by sailors with a wide weight range. See the videos and photos. Stability created by the foil is your biggest friend.

Why are the foils bigger than usual?

Early and comfortable foiling is the concept behind the boat. Large foils help make the boat fly at low speeds, while at the same time helping a comfortable ride at high speeds. The surface piercing tips help in the comfortable behavior without the need of an active mechanics. No moving parts needed!

Surface piercing foils?

The surface piercing configuration creates the automated ride-height. The faster you go the more the boat will rise. At the same time the foil will pierce through the waterplane, and the working area of the foil is reduced, as part of it is traveling through air. See the animation for an explanation of this behavior.

What kind of speeds will the boat reach?

The boat is designed with comfort, easiness, and early take-off in mind. Absolute top speed is not the goal, although reaching 20+ knots is still very exciting! Simply enjoy the quiet flight, no more rushing water along the hull surface.

Transport and storage

The 4,30-meter length makes the boat suitable for traditional dinghy trailers and boat parks. With the lifting boards in the up position, the boards sit within the maximum boat beam. Removal of the foils to store them at home takes two minutes and can be done without any tools. When you’d like to drop the mast; simply split it in two pieces and it will fit within the maximum length of the boat.
