    Thanks Arne! I actually still have the plan you sent me for my old Westsail 32 a few years ago! I am trying to decide between a sloop or schooner rig. The interior accommodation has a lot to do with it…but I also want the best possible sailing rig for cruising. Most C-Mists were Ferro ..but this one is fiberglass!

    Ok Jonny,

    new boat (ferro?), new plans. The C-mist is also 32'  -  I once bought the plans for it, but had the common sense to stop there.

    Here is a sketch of a sail plan I did for a Westsail 32.

    Hi Jonny

    Could I suggest you have a look at my last update on the Ingeborg project, here. The 22 photos, so far, shows in some details how the mast step and partners were constructed. I basically used the same method when rigging the 3 ton Johanna, and have had no problems. The mast step of Ingeborg is probably an overkill, but that is how it should be  -  a failing mast step would be a major pain.

    Oh man ….. how do I say this? ! I hate quitting a horse mid stream!

    My beautiful Storfidra is about 75% done …. and …..gulp …..I just bought ANOTHER boat!

    I can't help myself! hahaha! Actually , I got an offer I could not refuse on a gorgeous Samson C-mist. She is almost identical to a Westsail 32. The builder passed on before he could finish her …she has never even seen the water.

    That being said , she has never had any hardware mounted to the deck , so , instead of converting her to a junk rig …I will BUILD her as a junk rig.

    Here is a link to the new boat:

    http://www.sailboatlistings.com/view/52294

    Isn't she cozy? The hull is 2" thick fiberglass in places. Extremely STOUT.

    I am thinking 2 masted junk schooner …but , I will definitely need help from all of you experts. (please!)

    As for The Storfidra: I cannot have two boats. And , unfortunately , I would rather put the next few months of money and toil into the new boat…so , she will be listed for sale as a "nearly completed project" 

    I am trying to get her cleaned up and cleared out this week so I can take proper photos.

    stay tuned!

    Hey Arne  and Mark

    The deck collar can serve different functions and that could change how it is designed.  On our Freedom, the mast partners transfer the mast loads directly to the deck and the collar serves to hold down the partners and as a location for the halyard  and other line blocks.  Our collar has about 5mm clearance to the mast.  It is not structurally involved in supporting the mast.

    Today I cut the hole and fitted the deck collar to the deck of my Ingeborg. The shown collar is this time made of aluminium. I had a workshop make it for me to my design. Such things are not cheap, and I wonder if this method would be just as good:

    Grind away the deck’s gelcoat on the area around where the mast should be, say somewhere between 50 x 50 or 80 x 80 centimetre, depending of boat size. Then just plaster up a number of layers of glass, roving or mat, say 1-2 cm thick (thicker closer to the mast), using plain polyester resin for bonding.  One could even glass in a stub of metal after having cut the hole in the deck. This kind of partners could be made plenty strong and would be a lot cheaper than taylor-made metal collars. You only need to keep the boat out of the rain while working on  it...

    Cheers,
    Arne

    I was thinking about making a mould to produce the deck collar out of grp.  Would the partner plate be strong enough in grp as well, I am thinking that it would make a tidier job inside to produce the part and then fit.  I wanted to make it with two flanges, bolted on the deck underside and and cabin comings with triangular webs between the two planes.  Would it be best to add Kevlar or just chopped strand and woven roving?

    Just copy, and paste by right-clicking in the message area:

    Make sure the image is substantially narrower than the message area. I.E. not much bigger than above.
