The MIT Sailing Pavilion has a UFO sailboat that uses wing-like T foils to lift the hull out of the water. This 8 foot 9 inch, 110 pound catamaran style dinghy "flies" above the water is a good introduction to foiling. It is stable at low speeds and is difficult to capsize in displacement mode.
Contents
Requirements to Sail
- Must have full membership (Normal Sailing Card)
- Must have sufficient ratings; either
- Helmsman rating OR
- Provisional rating and at least two of the three high(er) performance boat ratings
- 420
- Firefly
- Laser
- Must take class to learn to rig/ sail
Safety For You (& The Boat)
Rigging the UFO
- Bottom of sail goes on first
- Might need 2 people to raise sail (1 pulls halyard back/down, 1 helps feed in sail)
- Put on cunningham before outhaul
- Don’t forget bottom batten
- Should be tied to cunningham finetune
- Latches for front foil are loose, make sure to tighten all the way
- Check for water
Derigging Notes
- Raise front foil in the water, then pull boat onto the dock to raise the back foil
- Careful not to hit rudder/foil against dock, but this makes it x10000 easier
- Remove bottom of sail first, roll as you bring down
- Since top batten is at a different angle from rest, reroll from the top so that this batten is aligned with the others afterwards
- Tie bottom batten to cunningham finetune
- Halyard gets tied to back of boom and cunningham
- Raise boom to decrease stress on spreaders
- Check for water
Sailing Basics
- Jibes are much much easier/faster than tacks
- Backwind sail to get moving
- Stand up, push boom away, point tiller away (controls flip when backwinding)
- Then sit, sheet in, head down for speed
- Windward heel and weight back/out helps get you foiling
- Heading up/trimming powers up, heading down/easing powers down
- Can’t hike the boat flat once you’re on foils, use angle and trim to control
