Foils deflect the water downwards as the boat moves forward – the upper surface also sucks the water down, both effects create lift, sufficient to lift the entire boat clear of the water. Compared with a displacement and planing surfaces, there is much less drag due to the greatly reduced surface area and elimination of wave making resistance – the boat can then easily go twice as fast as when pushing water with the hull!
Unlike cats and trimarans, which use 3 or 4 foils, we fly on just two foils which have less drag. A secret to dinghy foiling efficiency is that the boat can be heeled to windward, especially upwind, enabling the weight of both the hull and rig to provide righting moment, which helps keep the boat upright against the breeze. No other type of sailing craft uses the weight of the entire hull to provide righting moment. This means we can apply more power and go even faster, with less drag than multihulls and even sailboards. You will experience this yourself when you foil your dinghy past Hobie cats !!
Our customers have already recorded over 22kts on a Laser dinghy. We have have yet to find the ultimate top speed, lets see what you can do!!
Despite first appearances, the low streamlined profile of a dinghy has very low wind resistance. At 20Kts nearly half the drag is wind resistance, so this is very beneficial.

Launch in shallow water from your trolley.
Foils are fully retractable.
