After I removed the rigging from the mast Robin Feloy serveyed the mast. His report is in the form of an email thread. Peter Newbery-Thornton of Devon Wooden Boats also looked at the mast on a separate occasion with Robin and sent the following email:
Hi Steve, I have just tried your mobile and left a quick voicemail. I met with Rob Feloy this morning and we both inspected your mast at Darthaven. The shakes in the mid-section of the mast go in between 30% and 50% of thickness and in some places have no more than 1 ½ inches between each other in the core of the mast. While it would be possible to get the mast fully dry and clean out the shakes to glue splines in, you would be relying on the strength of the glue bond and splines to hold the mast together. In my opinion and Rob’s you do need a new mast, there are 3 options, you could have a solid traditional grown mast, a solid laminated mast or a laminated hollow mast. Before being able to work out estimates for you, I need to know a little more about the boat. I will give you a call in the morning to discuss.Kind regards, Peter
... then measured thickness of 'boom plate' (0.048m)....
This is a description of Shaula's rigging from the top of the mast to the bottom made in late December 2015 when the mast was removed at Darthaven Marina. Click on the photos to enlarge them.
After removal from the mast the rigging was taken to Traditional Rigging in Underfall Yard, Bristol for renewal.
The truck (wooden cap) which had a combined tricolor and anchor light on it was removed in early spring 2015 as it had a lot of rot in it. There is significant rot at the top of the mast.
Port cap shroud sits on top of stbd one at top of mast. So, the first to be put on (the bottom one) is the stbd cap shroud. The second to be put on (the top one) is the port cap shroud.
The VHF aireal was wobbly as its screws were loose.
The wires for the VHF cable and tricolour and anchor lights were led up the port cap shroud.
A Pulley wheel set into the mast just below the hounds for the cap shrouds is presumably for the topsail halyard
There is a shaped block of wood bolted through the mast just below pulley wheel. Appears to not be in use. What is it?
At the base of the painted and slightly thinner top mast section is a galvanised ring held on with two stainless screws. It has 4 eyes. Forward eye for Rotastay furling gear, aft eye has short chain to upper gaff peak halyard block. Port and stbd eyes attach to the upper end of the back stay loops. Port and stbd eyes also have short sections of chain which join on the forward side of the mast and attach to a tuff block with braided halyard reeved through it. One end of the halyard goes through a snap shakle attached to the stainless bow shakle attached to the forward pointing eye of the middle 4 eyed galvanised ring and at its end it is bent and taped round a plastic thimble with little galv shakle on it. The other end of the halyard is free.
There are small galv plates with a central hole in them screwed to the mast directly below port, stbd and forward pointing eyes. The forward facing one is slightly bigger than the other two. I do not know the function of these.
Two larger but very similar galvanised rings (screwed on better) are about 1 foot down and the next another foot down making 3 such rings in total. The Middle galvanised 4 eyed ring has a gaff peak halyard wooden block attached aft by a galv shackle direct to moused hook on block ie no chain. Nothing is attached to the port eye. There is a line to the radar reflector from the stbd eye. The forward facing eye is attached to a tuff block by a stainless steel bow shackle. A 3 stranded halyard free at both ends is reeved through the tuff block.
The lowest 4 eyed galvanised ring has nothing attached to its forward pointing eye. There is a short chain from the aft eye to a wooden gaff peak halyard block. The port and stbd eyes are attached via short chains to wooden blocks that form part of the topping lifts.
There was a Wobbly steaming light on the forward side of the mast about 18 inches above the spreaders.
About a foot above the spreaders is the throat halyard crane. This consists of a galvanised rod with an eye on it passing through the mast and projecting aftwards. There is a nut and washer on the forward face of the mast securing it. A bracing strut angled down at about 45 degrees bears on the aft face of the mast below the eye. The eye is shackled to an eye on a double sheaved throat halyard wooden block reeved with a 3 strand rope. The lower end of this block has a flat metal protrusion with a hole through it (becket) which is shackled to a thimble with rope bent round it. So, there are 5 strands of this rope leading away from the block.
There are two wires looped over the throat halyard crane. One is is a properly served and leathered eye which leads all the way to a dead eye at its other end and is presumably the forestay. The other is a short wire strop covered with plastic tubing. Both ends of the strop end in galvanised thimbles which are shackled together and also to a stainless steel shakle attaching to a tuff block which has a shakle at the other end too. The lower shakle joins to stainless thimble with a length of 3 strand rope spliced round it. This rope leads down and through a tuff block and comes up again through the top block and back down to a free end. I am not sure what it is for.
Below the throat halyard crane there is a loop of webbing bearing on the spreaders. The free end leads though through the loop and is attached to a galv shakle joining it to a tuff block. There is nothing reeved through this block and it is not clear what it is for.
The through mast bolt for the galvanised spreader brackets also go through downward and aft pointing flat sections of galvanised metal on the port and stbd side. These have holes drilled at their ends which are shackled to galvanised thimbles. Wires spliced round these thimbles lead down to and around metal blocks and then up to the top most galvanised 4 eyed ring fittings described earlier. From the lower end of the metal blocks a shacle leads to a thimble with spliced wire running down to back stay attachments to highfield lever.
The 4 lower shrouds: (1st on is bottom) 1st on stbd fwd; 2nd on is port fwd; 3rd on stbd aft; 4th on is port aft.
(steaming light and spreader down light wires run up stbd fwd shroud. Down light wire bifurcates in film cannister just below the spreaders)

Material must be protected from U.V. and chafe by a sheath. Sheath can be taken as an overbraided core over the main load member of the same material or another type of material. The strength of the fibre must be equal to or greater than that of the appropriate stainless steel wire. The wire shall show no significant signs of corrosion or weathering. When plastic tubing has been used it should be cut at its lowest point to allow any water to drain. 17.18 Lifelines shall be taut. When a deflecting force of 50N (5kg) is applied to a lifeline midway between supports, the lifeline must not deflect more than 50mm. etc etc
