Rigging Hobie Alpsh 6.0

Question
I bought an old windsurfing board.  Need some help rigging.
How do I rig the boom to the mast.  There is a 1/4" line connected to the boom.  Do I lace it around the mast as tight as possible?
I am having trouble moving the mast base forward and aft.  There is a plastic cylinder connected to a shock cord.  There is a 1/4" line that looks like it moves the mast base.  It moved back.  Can't move it forward again.
Not certain what the little lock is on the rear of the aluminum extrusion.  It locks ok but doesn't seem to do anything.

I have some pictures I can send you so I can describe the parts better.

Thanks,

Don

Hey Don,

For all your rigging instructions, go to my previous answers and look on Page 7 near the top for 'how do I set up my windsurfer'. There is a diagram and a key that lists all the parts. There is also a lot of rigging info on Page 9 near the top in 'running ropes on the sail'. I've copied a section that describes the boom to mast connection for your rig.

Boom to mast for a tie on type boom. Stand the mast up and hold it close to you. At the point where it is level with your sternum grab the mast with one hand and line up your thumb with your sternum. Lay the mast down holding onto the marked spot. You will be tying the rope on just above the point where your thumb is.

Now take your rope and make a loop with it, lining up the ends of the rope. Now loop the rope around the mast and thread the ends through the loop. Do this again so that you have two loops around the mast and the ends are through the loop. Snug the rope against the loop ensuring that the loops around the mast are laying flat to the mast and not crossing except at the rope loop.

Now take your boom and determine side should be on top. For all booms, where the adjustment pins and holes are on the tail, these should always down to allow water to drain. Slide the tail of the boom over the mast and work the boom head down to the rope on the mast. The mast should be under the boom head and over the tail of the boom and the boom should be laying parallel to the mast. There should be two holes in the boom head. Thread one of the two rope ends through each of the holes. Now tie a square knot in the ropes. Square knot is - With a rope in each hand, put right hand rope over left and loop (just like tying your shoes), then take left hand rope over the right and loop (just like tying your shoes only backwards) (unless your are a lefty and you do it opposite :)
Tighten the knot.

Now grab the mast above the boom with your right hand and lift. Grab the boom about 18" from the mast with your left and swing the boom away from the mast. The rope should be tightening and wedging the boom to the mast. If it feels too tight, back up and loosen the knot a bit. If you get the boom to where you are able to connect the outhaul and it is loose, back up and tighten the knot.


It sounds like you may have an adjustable mast track. The little lock on the rear of the aluminum extrusion aka:mast track should flip up and forward to become a pedal. Depress the pedal to release the mast so it can move forward and back. Release the pedal to secure the mast in position. You can press the pedal back to the locked position if you don't feel that you want to move the mast while sailing. It's a good idea to lock it while you are in the learning stages. The shock cord to the plastic cylinder is a Euro thing. All windsurfers in Europe required a safety line to secure the mast to the board in case the mast became separated from the board. It is not a rule any more but all older boards had them. You can remove the cord.

Let me know if you have any more questions. Feel free to send a pic of the mast track. Include any mast base parts in the pic and I can verify the type of track you have and if all the parts are there.

Hope this helps.
Keep on sailing,
Windlover
