Hobie TriFoiler, Assembly Manual

De-rrigging

The de-rigging process is the reverse proce-

dure of the rigging process. Here are a few

reminders. The first step is to get out the sail

covers, foil covers and put all the spar racks on

the boat. Remove the sail link. As soon as you

undo the outhaul for the port sail, connect that

boom to the king post.

Do not release the backstays

without clipping the port boom 

to the king post!

Take off the sails, starboard boom, mast rota-

tors, foils, shocks, sensors. 

Check the port

boom connection to the king post!

Then

lower the starboard mast. Stow the starboard

mast and compression strut. Lower the port

mast and stow the mast and the port boom.

Remove the amas and the beams. Clip on all

bungi cords, double check everything and you

are ready for the road.

Sensor Retraction Lines

The two red lines with a red knob will pull up

on the sensors. Raising the sensors off the

water when the wind is light will greatly reduce

the drag at low speed. Lift the sensors up

when the wind is light, there is no hope of get-

ting onto the foils and when you put the boat

on the beach.  

Be careful when moving the

boat backward or sideways on the beach

so that the sensors do not get stuck in the

sand and damage the sensor arm or the

bow of the ama.

Raising the sensors off the water in marginal

wind may allow you to get onto the foils in

slightly less wind than otherwise possible.

Once you get onto the foils, make sure these

lines are all the way out or the sensor will not

stay on the water and the boat will fly too high.

Foil Retraction Lines

The blue lines are meant to retract and

deploy the foils; however, there is some tech-

nique required to retract and deploy the foils.

Deploying the Foils

To lock a foil down it is necessary that the foil

being locked is on the leeward side of the

boat. If the foil is on the weather side of the

boat,  water pressure will prevent the foil from

coming down all the way and locking. When

the foil is on the leeward side, the water pres-

sure will push the foil down and in. It might be

necessary to sail on both tacks to get both foils

locked down. If the boat is in irons, it is possi-

ble to simply push the sail link from side to

side, which will move the boat side to side and

lock both foils down.

If you release the line and the foil does not

go down, see if it is cleated in the cleat on the

beam. If it is, pull on the line to un-cleat it. If

the line still does not go out, try releasing the

sensor retraction line. If the lines are twisted in

the beam, tension on the sensor retraction line

can cause too much friction on the foil retrac-

tion line.

Retracting the Foils

Do not retract both foils unless you are ready

to jump out. The boat will not go to weather

USING THE TRIFOILER

Controls  and  Operation

Steering

The standard TriFoiler comes with bicycle

steering, meaning if you press with your right

foot you will turn left. It can be switched to air-

plane steering, ie, where if you press with your

right foot it will turn right, but bicycle steering is

highly encouraged.

In the event of a problem with the steering

pedals or during beaching and launching it is

possible to steer the boat while seated on the

rail in the back of the cockpit.

Mainsheet

The center large rope is the mainsheet, or

more precisely, it is the traveler control. There

is a 4:1 purchase system in the main hull

which pulls the sail link to center line and thus

brings the sails to center line. There is a large

cam cleat for the mainsheet.
