Help...How do you get a 2 piece mast unstuck?
Spencer Lister
(probably with sand). Standard measures to separate it (brute force)
haven't worked. Does anyone know of a good way to get the 2 pieces
separated?

you have to. Clamp one on both sides of the joint, and see if you can
work it back and forth. This usually works.

Tie one end to somehing solid and the other to your car. Start the car,

My favorite, which I've done a half dozen times, is to tie one end to a
fixed object (e.g. tree) and other end to a powered object (e.g. car)
then slowly move the car away from the tree. The hard part is to tie
good knots that will hold and untie. I usually go for a slip knot with
about five wraps around the mast. Think what you want, but, it works.

two booms, one above and one below, and then twist. It gives you great
leverage. Also, if the booms slide, try using an old bicycle intertube
inbetween the booms and mast to provide better gription.
Good Luck.

hitch and pull. It works.

The best method I've seen is to simply get some help from your sailing
buddies or whomever you can find. Start w/ 4, put 2 on each half and twist
and pull against each other until it comes loose. This works for 90% of the
stuck masts I've seen. Still stuck? Get 2 more people... Still stuck?
Get 2 more... Still stuck? You've got the idea.

rubber mallet while twisting or pulling apart the sections. You can
use several friends to help with the twisting and pulling or you can
use the clamp on booms or a rope wrench made by wrapping a piece of
rope around a screwdriver and twisting.

Hi!
Take to booms, fix them to the two parts of your mast close to the
joint. Now you can use the booms as handles to turn the two pieces.
With a little luck you get them a part pulling and turning.
A little care is needed when fixing the booms not to crush the mast.
Good luck!

Yes, I've tryed this, but most of the time, the boom slips around the mast
instead of turning the mast pieces. The best method I've found yet is to get
together as many people as you can and let them twist and pull on both mast
pieces in opposite directions.

I have tried this technique but when I started the car, the strap broke,
the mast did not move....by the way that mast is in the garage someplace
still in solid one piece....I bought a new mast since...

Still stuck?? Congratulations, you now have a *one* piece mast! ;^)

possible. Don't leave your rig on the water's edge, half in the sand, half under water. Clean sand off of your rig after you sail. 99% of your problems can be avoided. For the
remaining 1%, the best method is lots of people pulling and twisting. If you can't get a lot of people, two people can increase leverage and grip wrapping short pieces of rope
around each part of the mast. Make about ten tight wraps, over and under at each end so the rope won't slip on the mast. The larger diameter the rope, the more leverage and
grip you will get. Two booms clamped to the mast may also work, but they do tend to slip. One last tip - get a rubber mallet. Use the mallet to lightly tap all around the mast joint.
This tapping action seems to help when nothing else works. The rubber mallet is also a handy tool for many other windsurfing assembly/disassembly jobs.

and the other end to the bumper of the car and pull it apart, make sure
you tie a line connecting the two pieces together in the middle where they
come apart. As you are pulling, the rope will stretch and when the mast
comes apart the rope will recoil and the mast will become an airborne
missle that will go through the back of your car.
Take precautions.

Get one person on each end and start shaking: get the mast oscillating
at its natural frequency with as big an amplitude as possible. this
works the joint -- in the right light you can see the sand particles
flying out. Alternate with a hard twist.
I have seen this work on a number of occassions where other methods,
including cars, straps, and trees and boom clamps failed.

Don't forget to use a mast protector esp on carbon masts.
Get a mate and simply twist - never known to fail.

You can support this (as well as ost of the other mentioned tricks) by
pouring hot water over the upper part of the joint.
BTW Spencer, did you suceed yet? which trick worked?

Try 2 clamp on booms, one on either side of the split. This gives great
leverage.

think I'll throw in a bit of analysis.
The reason that mast joints stick is usually sand.
If one analyzes the stresses on the mast joint you
will see that the the clearance (O.D. of the joint to
I.D of the top portion of the mast) is skewed from
the front side of the male joining piece to the rear side
of the top section female joint.
What really causes the mast to stick is that when you
release the downhaul and outhaul the skewed clearance
goes away and the clearance becomes symetrical around
the centerline of the two pieces. This would be wonderful
without the sand trapped in the skewed clearance areas
at the lower front and upper rear of the joint.
In my experience the best way ro redistribute the sand is to
turn the two parts radially about the centerline rather than
try to pull the mast apart longitudinally.
A little twisting back and forth quickly spreads the sand evenly
around the joint and the two parts are no longer trapped in
the skewed position and the mast will pull apart easily.
If there was a way to bend the mast back in the same direction
and to the same degree as it was when the sand entered the joint,
and pull it apart at the same time, it would release easily.
The reason that the two boom method and the rubber mallet method
work a little better than others is the sand gets spread evenly in the
joint sooner.
On this same idea, I have been orienting my masts with the labels
forward for several years and have had no masts fail and no stuck joints.
I believe it's will extend the masts life quite a bit. What research I have read
indicates that composite structures (like sailboard masts) fail much sooner if
subjected to varying interlaminar stresses. If you always bend the mast from
the labels back then the interlaminar stress is always in the same direction.
Also as almost all composites will take a "set" over time it seems best to have
the "set" working for you rather sticking out in some uncontrolled direction.
Envision if you will someone with a mast that has a 1" set from the labels back.
Would you rather bend this "set" back with the downhaul and outhaul, or would
you prefer to have to fight the "set" to get the bend you want. Or even worse if the
set runs on the side of the mast you will have a significantly different foil depending
on which tack the sail is on.
The only time I don't bend from the labels back is if the mast has a natural "set" when
new in which case I will mark the convex side of the set and always orient this to
the front of the sail. Later sailquik

Hi,
There was a whole load of (serious) answers to this ages ago. Are they
archived anywhere, or in a FAQ? Seems like maybe it should be.
My standard solution is to get two booms and put them either side of the
centre really tight. Then simply use the leverage of the booms to twist
the two pieces apart. And if that doesn't work squirt some WD40 oil in the
gap first.

person should start shaking strong (the middle of the mast moves
up and down) for one minute or so.
Then you should be able to seperate your mast (turning both
parts, not pulling. Some force is still needed, but it's much
easier)

and it took four people on each side before we got a mast apart. Of
course, you want to twist it, don't pull.

on either side off the mast. Use the booms like wrenches and twist in
opposite directions. Good Luck.

something solid that won't damage your gear too much (and that the owner
of won't mind. Old Chevy's or 55 gallon drums are OK, BMW's and Grand
Cherokees are not...). The end is on the ground.
Then, gently bounce on the center joint a few times. Rotate the mast
about 180 degrees, and do it again. Then, grasp each end of the mast and
twist the thing apart.
I've been able to get my gear unstuck using this solo method when the day
before 4 people couldn't get it apart. And yes, it will scare the hell
out of you to bounce on your rig...
I've gotten in the habit of assembling my mast IN THE WATER and carrying
it back to my sail to rig. I get a lot less sand stuck in it. I met a
guy who puts vaseline on the joint sleave. It stops sand from having a
place to go. But, I'm sure it gets on his sails.

One person on each boom and twist. Gives great leverage and almost always
works.
SPORTS LTD
hitches (thjey tighten automatically) use a large diameter rope. Attach
one end to something solid (telephone pole at Leo Carillo) and another to
your car bumper. Go for it.

You may have already tried this but if you get a person at each end of
the mast and one person to furiously "waggle" the mast up and down can
break down the salt that usually causes 2-piece masts to stick.
Best of luck.

Martijn
and the other on the other piece.
Then you have much better grip.
Now you onl;y need another person.

Chris,
here is an ever working trick:
Use at least two, preferably four wishbones to unstuck your mast.
Here is how: attach 2 wishbones on each side of the joint (you may
need some duct tape to enlarge the diameter of the mast near the joint
in order to have a very tightly attached wishbones) then twist the
two parts using the leverage your wishbones gives you until the mast
is unstucked.
Sorry for my fabulous english.
Best of luck from Quebec...
