A-231 Periwinkle

same material???
because: like likes like?  
Dunno: similar expansion, same wood no problema, that sort of thing.  Wouldn't use a rottable wood like beech dowels, right?
Ready made mahogany dowel is catalog available.

I'm the sort that if I used the buscuit cutter I'd have to hand make the buscuits out of mahogany too.  And not only that, I'd have to turn the grain of the inserts so they were vertical to the grain running in the coaming.  That's the sort I am, and that's why I'm still doodling around on the boat and not SAILING!!!

You guys figured it out.. the cleat is for the furling line. It runs through a copper fair lead in the coaming and then forward just below the portlights. I stole this idea from a Cape Dory 33 that was once in the family.

ebb.. I'm not to worried about the mix of wood types in the repair pieces (i.e.  beech vs. mahogany vs. teak) since the joint is sealed with epoxy. Were this some form of marquetry applied to the surface, I'd worry a lot more. The repairs are two seasons old now with no sign of movement.

cheers,

ebb - Think the split occurs from the upper portion of the coaming being free standing.  

On my boat the split appeared to be the result of the winch base being loosely bolted to the deck. As a result of the loose winch base, the coaming was twisted everytime the winch handle was pulled towards the cockpit. Once the winch base was secured and the plank repaired, I've seen no movement of the coaming.

One other standing request that I've received was for details and dimensions of the chart plotter mounting bracket:

[bill@ariel231]

In the attached sketch you'll see the major parts:

* 12 inch section of Harken 1 inch recirculating ball track
* Harken car to fit the track (tapped to hold a 5/16th" NC bolt)
* teak - base containing a 5/16th NC bolt, a stainless steel spring (1" x 3" or so)
* teak - cap (for the base)
* teak - transition from Harken Car to the plotter arm

Next a close up (before disassembly):

here's a photo of the base (note the slot between the track and the base, this acts as a detent to hold the plotter in position):

The cap that covers the rough end of the base & plotter arm is also formed from teak and fastened with #8 machine screws here's a close up:

one more section of teak makes up the transition from the harken car to the chart plotter mount:

If anyone is crazy enough to try building one here are the drawings for the base, cap and transition sections:

Does it plot your charts or chart your plots?

Holy smokes Bill! No wonder your boat looks so good! -- you must be an engineer...  :eek:

thanks, actually when I use it at all, I just use the GPS repeater & cross track error pages (large text). I've used a lot of electronics charts (like CMAP) and written software to do the same. I still prefer paper unless it dark, rainy and I can't see beyond the bow....

In answer to Frank's "what's new" challenge of 7/6/2006... A-231 does occasionally leave the dock. Although far less often than she deserves to....
