Core Sound 17 #159 Refurbishment

[Paul356]

Don, on your question about the mainsail snotter line:  I have what I think is the same rig your photo shows.  I have a long snotter line running down to a turning block and then back along the side deck to a spot about midway back on the stbd side, along with all the other foremast lines.  (I can raise, reef, snot(?) and downhaul the sail from that position).  As for the snotter line, when pulled tight in use, there is plenty of extra length back in the cockpit.  When I pack up the boat, I take off the sail slides, take the snotter hook off the mainmast strap, and run the snotter line all the way out to its end at the cleat on the side deck.  That gives me enough slack to put the sprit and the sail back in the cockpit.   I do not otherwise need to derig the snotter line.  With the extra length in the snotter line, I can move the spirt and furled sail back into the cockpit for storage.

As an aside, I also have plenty of length in the main halyard.  Again, when I derig, I tie off the lifting end (on the snotter strap, in fact) and run all that excess from the aft end forward of the midship cleat.  This lets me lift the mast clear of the step and lay it down on the boat without otherwise derigging the halyard.  I have the reefing lines and downhaul of hooks so that I can derig them from the sail as I take it off and lay them on deck, so they do not factor in lifting out the mast.  Hope this makes some sense.  I'd take a picture, but  the boat is in a shed some miles a way, and under cover as well.

Thanks, Paul.  I’d love to see some photos, but there’s no rush.  I’m not touching it (much) until I get this trimaran out of here.

[Don Silsbe]

@Randy Jones— What a great idea!  I’ll keep that in mind, long term.  My current sails are in pretty good shape, but they are 17 years old, nonetheless.  

[Don Silsbe]

New question:  How difficult would it be to retrofit a tabernacle to the main mast?  What about the mizzen?

[Captain Tim]

This from the guy that cut a great big hole in someone else's boat last winter?

[Don Silsbe]

Oh yeah.  That.

[Don Silsbe]

I was most concerned about access..  i think I can get to both sides of the first bulkhead though the forward hatch, right?

[Hirilonde]

@Don Silsbe Can't you install the first bulkhead from the cockpit?

[Captain Tim]

Couldn't you take the foredeck off then build the tabernacle then put the deck back on with the needed cut out?

I’m not sure!  I don’t have the drawings, and the boat is currently under a tarp.  I’m hoping to cut the final opening in the foredeck, and drop the assembly in from there.  Not sure, but I was hoping to get access to the after side of bulkhead #1 from the cockpit, to shoot some temporary clamping screws.  A screen shot of the plans would be helpful.  But I have time.  I’ve got a trimaran to build first.

[Captain Tim]

Sorry can't help with plans, I built a Spindrift 11'

[Paul356]

You can get to the front of the first bulkhead from inside the bow compartment, although some of it is going to be a stretch.  The main mast is very far forward.  Just thinking about it, I can't quite feature how you'd get the main below deck level to pivot forward.  But, I do have plans and can try to send you some when I return home tomorrow or Sat.

Don,

Tabernacle conversion on my CS17 Mk1 mainmast is also on my project list.  Alan's CS15 construction video suggest it would require some remodeling and a new deck,  but it doesn't appear difficult. 

My Belhaven 19 has a mizzen tabernacle that is very convenient and works well.  You could do something similar but I don't see much need for a mizzen tabernacle on a CS17 Mk1 where access is easy.

@Hirilonde— The first bulkhead is in place, and has been since 2007.  I’m considering a retrofit of a tabernacle, to make my life easier in the upcoming years.

[Hirilonde]

I am considering adding a tabernacle to my Lapwing. Does B&B sell the plans?

[Don Silsbe]

I’ve asked B&B, and am waiting a reply.

Don, here are some excerpts from the plans.  (you can ignore the lines in green and the 10" and 24" notes.  I was thinking out loud.)  As you can see, the front bulkhead is accessible from the front hatch, with a stretch. But the main mast step is very far forward. And as an aside, I don't think I can reach the step from the hatch as is.  Whatever I did to the step I did before I installed the foredeck.

 

I for one don't see a tabernacle reaching down to the step.  I think at best you'd be looking at a two-piece setup, meaning partial mast (or tabernacle, I guess) reaching up through the deck level and then the main mast pivoting up into that.  One caution is that the main sail foot comes down very close to the deck on the aft side of the mast, at least as the sail is cut now.  All that caution aside, you're a pretty clever guy, I suspect, so it will be interesting to see what you come up with.  And I'd be real interested if Graham has plans.

Thanks, Paul.  This is very helpful.  At least it shows how things are at present.  Maybe, at some point in time, Alan or Graham will chime in.  I respect it that they let us chew on the bone for a while.  When they speak, it often closes the conversation.

[Don Silsbe]

Oh, I see.  The first bulkhead is aft of the hatch.  I thought there was a bulkhead directly behind the mast.  That’s the way it is on the mark 3.  It turns that small compartment into an anchor rode locker.  I probably need to add a bulkhead then?

[Paul356]

Right, no bulkhead immediately behind the mast.  If you make an open anchor locker before the mast, you will need to do some sea-proofing in the bow compartment.  Now I see why you were asking about the first bulkhead.  You were thinking bow, I was thinking back where the cuddy starts. 

 

Come to think of it, a little anchor well up front would probably be nice, tho.  Even if there wasn't a tabernacle.  But then the king plank wouldn't run up to the bow, and then some added reinforcement would be required, and then....
