Broken Mast Help Please

So yesterday while sailing in less than 20 knot winds the port shrouds snapped and instantly down ocmes the mast over the starboard side. Luckily no one was hurt and we got into calm waters with the help of a tow.

Now I need a little help. It looks as if there was some serious cavitation going on and that this would have happened eventually anyways. It ripped out the bolts and the damage is only at the bottom 2 inches of the mast. A few people at my marina told me that if I get this to a boat yard they should be able to cut the damaged bottom part off and re-drill out the bolts after we replace the step base. I am going to have them re-do the shrouds anyways so they will just need to be a bit shorter. There's also the issue of the slot being bent out a little. Is this something I put a collar over?

If anyone sees this from the bay area I was thinking of taking this either to Svendsens or SF Boat works. I figured they're probably going to have to haul this out so I might as well paint the bottom while its out right . Alright guys let me know what you think.

Thanks!

You might try looking for a used mast on E-bay, or at a local salvage yard. It looks like you had a lot of electrolis or corrosion on the base of the mast. Good Luck

Sorry to hear about your demasting. Why/where did the shrouds break? At the swage? At the chainplate? At the turnbuckle? How old was the rig? How large is the boat? Just curious...

Pics of the broken shrouds would be good.

I don't know if it will help but over here in Perth/Fremantle we have to lower the mast to get from the river to ocean due to low bridges. To do this we have a hinge set up about a foot above the deck. Below this is normally another piece of the same section. If you like I can take a photo of it to send to you. Only problem is that it's already dark and I'm on a flight early tomorrow morning. I will be back on 6th Oct and can do it then if that helps. This arrangement is really strong. Back in the late 70's/ early 80's an IOR maxi used to be here and had a similar set up.

Your kidding me right?
Six days ago you started a thread entitled


How do I tighten a CDN Roller Furling Jib

HEre are some images of the roller furling I have that came with my boat. I can't figure out how to tighten this. Do I need to take the drum off or something? OR do I need to go up in the bosuns chair and do it from the top? There is a lot of play in the shrouds (even if there is a shroud under there...I don't know). I keep tightening my backstay but I can see now that my mast at the top is leaning backward....yikes. Help!

I responded to your post with this...

"You have what appears to be an older CDI furler. There is a headstay and likely a turnbuckle inside. You do have to disassemble the drum to access it.
In the photos, it looks as though there is no tension on the stay at all. It sounds like your headstay has broken inside the furler.
I would recommend that you lead some halyards forward to hold the mast up and call a professional rigger. Immediately."

So you go sailing????
What part of Immediately didn't you understand???

I inherited a Pearson 26 that was dis-masted after the starboard chain plate cracked and yielded. It broke right at the spreaders. The previous owner looked for a matching piece of extrusion for a year and a half before he was transfered and I then looked for another 9 months (through a bad hurricane season as well) with no luck.

I had to improvise and buy an "equivalent" stick - which causes a new set of money issues by needing a new step, hardware, spreaders and mainsail.

Although I have never been in a dis-masting incident, from what I have seen and heard - check your rigging and chain plates regularly. It is too dangerous and expensive to take your standing rigging for granted.
