attach a boom on each end and counter rotate

Bender,
The most common remedy is to get two booms and clamp them onto the respective halves of the mast, so you can get some extra leverage when twisting.

Good Luck

Just "bend" it apart Bender.

Chances of getting it apart are high. The boom on each side is the goods... also, worth wobbling the mast to try and free up whatever crap is in the join...

Grab the base, and bang the top on grass or some smooth surface, the vibrations should unblock the joint in a way that is probably better for your mast than putting a big load on each side and twist (booms or clamps). Repeat that until u can pull it appart. Hope it works

If you can't rotate it out then "bouncing" it is the next stage

Wet the joint touroughly

Support both ends of the mast at a convenient height for you to bend the mast at joint.

Make sure the ends are padded where the mast rests on the support.

Now the fun part.

Using you body weight start flexing the mast at the joint. Whilst doing this occasionally rotate the mast.

After a while you will notice a gap starting to form bewteen the sections, keep going, add more water if drying out.

When gap is about 3mm try rotating your mast, it should be a bit looser, if not resume bouncing.

Normally takes between 5-15 mins and is a good aerobic work out.

have fun

I agree with Elmo... best bet is get 2 guys to help, they support the mast on the their shoulders whilst you hang off the mast around the join, keep rotating it, bounce up and down, then let go and get the two guys to shake the mast as hard as possible. I have never had a mast stay stuck after this approach... It's also interesting to see the mast flex when you have someone weighing 75kgs hanging off it!

Good Luck!

Maybe its actually a one-piece mast and you don't realise.

Spray some WD40 into the ferrule leave for a day or so and then use the two boom method as everyone has suggested, never fail solution good luck

i've tried many of those ways and none worked for me.

what i did is i put some detergent in it and left the mast sitting up side down over night. The next day i took it into school to the tech center and put the skinny end of the mast in a vice. Then i rounded up about 10 of my mates and some teachers and just got to twist as hard as they could. Came apart prity easy.

I found this way good because attaching booms and having many people on each side didnt work for me. Its also good because you are not at risk of breaking the mast totally.

I've pulled apart 3 masts this way and havnt been beaten yet. Hope this helps you aswell.

Let us know which way worked best. i will be interested to find out.

Five guys on each end - twist,,,easy!! Heaps better than the old "boom on each end" method.

Put a rope aroun a tree and on one side of the mast, and tie the other end on your car. put firm tension on it and tap with a screwdriver end at the joint.
worked excellent on two masts.
use some bootys or neopren to pad the part where you tie the rope onto the mast.
good luck.

HE he ... I remember a report from a bloke who had a mast that'd been stuck for ages. He ended up heating it on the barby to take advantage of some differential expansion. I dont think it actually caught on fire but it was totally rooted. Poor bugger ... *giggle*

Now that separation has been successful, can I suggest my technique for avoiding getting the two bits stuck in the first place. First, get the sticky outy bit- lets call that the male bit, and slide it gently into the bit with the hole- lets call that the female bit, then push the male bit in as hard as it will go, and here's the fun bit, stay with me, pull the male bit out a bit, and push it back in. Do that a few times until you get really excited (about going for a sail) and until the male bit slides really easily and smoothly in the female bit. Helps if you start with a clean male and female bit in the first place, because its sand and grit that can make the whole experience really unpleasant, but ramming the male bit into the female bit a few times,then withdrawing a bit and repeating that and even giving the two a bit of a twist when you withdraw the male bit gets rid of any sand and makes it really really satisfying. Then when you want to withdraw the male bit from the female bit at the end of your (sailing) session, you can easily retract it, and the female bit can't stop the male bit from going where you want it to go, which is back into its pouch thingy until the next time.

OR, you could just rinse both with water thoroughly.

your mast must not have been as stuck as my couple that got stuck. We tried 2 booms on each end of the joint and still wouldnt budge. I found u need one end to be compleatly immobilized and the other to be still, to have any effect with people twisting the mast. Otherwise with so many people trying to twist so hard, it moves around to much making it much harder.

Yes, Pugwash. That certainly works too. But not everyone washes their male bits after they've had it in the female bit. And I'm not even going to contemplate whether the female bits get washed!
