Subject: Use Sta-Lok or Norseman Fittings
In reply to: Mike Anthony 's message, "M-40 headstay, I need help" on - Sunday - 09/17/06 - 6:36pm

I'd use Sta-Lok or Norseman fittings. First, I'd measure the distance from the end of the mast where the mast steps on the cabin top to the masthead fitting ("A"). Next I'd measure the length from the mast where it steps on the cabin top to the cranze iron fitting on the bow sprit ("B"). I'd solve the geometry problem I thought I'd never use in the real world: (A x A) + (B x B) = (C x C). "C" should give a rough estimate of the length of the forestay. Then I'd add some extra feet (5 or so) to account for the height difference between the deck and the cabin top height and to account for the B I made in Geometry! Given the "I" length in the M40 specs listed on this website, I'd guess 55 feet of wire would be enough. I'd make a wire of this length and attach a Sta-Lok or Norseman eye fitting at the end where it attached to the masthead. Then I'd attach it to the masthead, step the mast, and then take the wire to the end of the bow sprit and measure carefully for the Sta-Lok or Norseman stud fitting to attach to wire. This is the tricky part. Better too long than too short! Also, keep in mind that the backstay(s) and the bobstay need to be properly adjusted. Cut the wire and attach the stud and screw it into the turnbuckle.

Capt'n Mike,

Thanks for the help, I will not be bending any sails for this short trip, however, next spring before I put her in I will have to hire riggers. I noticed you indicated the back stay and bobstay need to be properly adjusted. If there are no sails how important is the tension as long as everything is tight and straight. Is this somthing I could do myself or am I going to need a rigger for this as well?

Thank you so much for your help

Island Mike

When it comes time to do the rigging, I recommend that you do it yourself with Sta-Lok or Norsemand fittings. It really is very easy AND not rocket science. Buy Brion Toss's book "The Rigger's Apprentice." I think you will find that it is a job you can do yourself and save a lot of money. You will do a better job on your boat than if you paid someone. Plus it will allow you the confidence to do your own repairs. For now, if you are not going to bend on any sail and are in somewhat protected waters, I think you could just use a high quality, low stretch line for the forestay... but make absolutely sure the line you use is rated for the load AND you tie a very good knot! But once again, rigging today with modern do-it-yourself fittings really is easy and if you do it now you won't regret it.

Capt'n Mike,

I think you are absolutely correct with all of your advice, as I look into it I am confident I can do it myself. You have been a great help, Thank you very much.

Hey Mike,
After my, sad and expensive, experience with (professional) riggers, the more of your own rigging you do the better. I agree with Capt'n Mike. You'll get a better job if you do the rigging yourself. Do get Brian Toss's Riggers Apprentice an learn to do the job yourself. You can even call Brian's shop an ask them questions, but watchout, cause they'll tell you to bring your boat over to the shop. For me and SHADOW that would be over a 1000+ miles up to Washington. You can get videos that show you how to tune your masts. If I'd known this before, my Mariner 32 would still be in the water an not on the hard cause the rigger tightened the shrouds to tight an literaly cracked one of the main beams under the main mast. So, anyway, that's what I've been doing all spring an summer long, digging out the broken beam under the mast. It's out now and I was going to laminate 1/4' strips of red oak with resorsinal glue. Like I'm the seasoned shipwright! I'm all ears if there are any other ideas out there in the Mariner family. So, don't let this avoidable situation happen to you.
Yours truly, Kathy Campbell
