Going up the mast (solo) and what to expect at the top...

I recently bought a new-to-me boat, a Halmatic 30, and I'm generally very pleased with her. However, as is the way with older boats, I have a snagging list of daft wee jobs needing attended to.

One of those jobs was that the steaming light wasn't working, and having already buzzed out the circuit at the cable join at the bottom of the mast, and found high resistance, I felt sure I would be looking at a wiring / corrosion issue somewhere. So, up the mast to the light just below the spreaders.

I should at this stage point out that I have never had a great head for heights; truth be told, it's more the falling down and going splat that worries me, but also, being a tight Scotsman, I didn't want to pay someone else to do it. So my method of getting up was 2 blocks and a long length of rope, a 2 step wooden rope ladder repurposed into a makeshift bosun's chair, and a looped line with a prussik knot on to the lifting line. So far so good...

I found it slightly hard going initially, but realised I had made the loop with the prussik knot a bit too long, and to make it tight was slightly above my reach, but anyway I made it up to the spreaders without any drama and opened up the lamp unit to find, as expected, green corrosion on the bulb contact terminals. I cleaned these up and all was well once more.

While up there I thought I may as well inspect the rig (becoming more confident at the height), and finally lowered myself down, pleased with my escapade and the lack of any death, especially in view of the need to attend a wedding later that day! However I noticed another issue that had been bothering me whilst out sailing.

The Genoa was unwilling to both roll out and furl back in, but easing the halyard fixed the problem. To cut a long story short, whilst up the mast, I could see that there appeared to be a halyard missing, and the Genoa was in fact hoisted by the spinnaker halyard which had been run through the guide about a foot down from the top of the mast and thence to the top hoisting fitting. But this meant that the halyard was fouling on the larger top furling fitting and was jamming it. So I will need to go right up the mast and run a new halyard for the Genoa.

I tried going up again late this afternoon, but to be honest chickened out at spreader height as I felt it would be too easy to slip out of the makeshift chair. I'm also a bit unsure what to expect at the top of the mast in terms of blocks, etc., for the halyard to be sent round. From looking through binoculars it would appear there may be a sheave at the front of the mast head and another at the back... The halyards run externally. Would that be correct? The halyard running over the 2 sheaves? I also need to fix the non working anchor light, so 2 jobs in one would be good, and it's one of those double decker type lamps (tricolour above all round white), does anyone know if tools are needed to open them or how they open up?

Also, looking for recommendations as to which bosun's chair I should buy... something safe and comfortable to work in. Thanks in advance for advice / observations, etc...
 
The problem with a bosuns chair is it doesn't lift you quite high enough to see the top of the mast.

I use on of these, but there are lots of variations on the theme.

It means you can stand up above the top of the mast looking and working downwards. Wouldn't surprise me if the previous owner lost the jib halyard so switched to the sp to hoist. Small fishing weight or drill on some fishing line to feed down the mast will help. Short length of bicycle chain also might work.
 
I have a bosun's chair from Force 4 and it seems to work fine. However, my wife winches me up the mast with the main halyard whilst using the spinnaker halyard as a safety line but I've absolutely no idea how I would go up there on my own so you're several steps ahead of me already. :)

I had to go and replace the batteries on my Tacktick wind instruments right at the very, very top of the mast, single handed, over a lunch break. Check out my tips on the end of this post:

The TopClimber isn't cheap (eek £300), but, err, its effective at dodging death, so that's a plus to it. If you consider you'll probably pay a man £100 to go up your mast, after 3 trips up the mast you are quids in. I have an additional fall preventer too on a separate line... overkill probably, but better than, err completelykill-ed.

Thanks. Yes, I have looked at a few of the bespoke climbing kits but the price scared me off!
The halyards don't seem to run inside the mast, so I'm hoping that should make it a bit more straightforward.

Yes that sort of thing looks ideal apart from the price right at this moment in time...
I do wonder if a home brew version using webbing for foot straps could be made up, and a chair for the upper part, prussik knot for each part, and a final one tied off to another halyard or the topping lift as a back up arrester...
Hmm... I hadn't really given thought to have the need to stand up to get above the mast!
 
stevie69p,

I'm not happy with heights either, but at risk of stating the blooming obvious, take care - one fall like that could easily mean a broken back, I'd want a very safe system with a Plan B safety line - can't you get a friend to help from the deck and be a safety assistant ?
 
If you have a furling Genoa take care that the halyard goes off the top of the genoa at an angle to the forestay not parrallel
to it.

The angle prevents the halyard wrapping around the forestay as the furler is turned then jamming it .Do a search on "halyard wrap" for more details .

Not a fan of them myself. I too climb the mast using ascendors or prussic loops on a bar-tight main halyard, one connects to a very basic climbing harness, the other to a wooden step, the latter allowing me to stand at the masthead, with the light, windex etc at almost waist level; once in position, loop a safety line around both yourself and the mast, then you've then got both hands free too.

If possible of course, have a separate halyard fastened to you as a safety line, with someone at deck-level to tail it around the winch; purely a fall-arrest, so no need for the second to be particularly strong.

Yes, it has a guide 'saddle' just down from the mast head that the halyard runs through and then off at an angle to the top fitting. This is why I was a bit confused initially as to what was going on, until I saw the halyard fouling against the top bearing and realised it was in fact (probably) the spinnaker halyard (which I will also need as the boat came with a cruising chute).

That might be another option i could try out... use the ladder as a step for the feet rather than sitting on it. I have harnesses available on board also, though a pukka climbing harness would be a better bet with the legs being through it. Which reminds me... I have a friend who is into climbing, so I can likely borrow a harness from him.

All great food for thought :)

Agreed, but there is an element of risk in most things. The back up line would be another prussik on separate line as a fall arrester. I sail solo, so expect to be able to manage repairs and maintenance solo also.

+1. You shouldn't being doing this stuff on your own. You need an assistant who can get you down if you have a problem, or call for help. This isn't solo mid-ocean.
 
1 Lack of death. Always a good thing. Please keep it that way. ?
2 No head for heights? Just like me. I’d have paid to have the mast lowered in order that I could check the rigging at ground level. I just prefer it that way…
3 Halmatic 30. Nice boat. Almost bought one myself a few months ago (but the one we saw needed too much modernisation for the asking price, with old rigging and sails).
4 The genoa halyard being run through a guide about a foot down is a normal thing to reduce the likelihood of the halyard wrapping around the forestay during furling.
5 Using the spinnaker halyard? Only you can tell this but I’d recommend you sort them correctly. I’d also recommend Dyneema (or equivalent) for halyards. Expensive but zero stretch. As a Scottish person it may be too painful for your wallet… ?
6 Easing the halyard made furling easier? It shouldn’t make much difference. Maybe it’s time for an overhaul of the bearings in your genoa furling system.
7 Double decker lamps are usually a bayonet fit and can be done by hand.
8 Which bosuns chair? See my note about getting the mast lowered…
9 Enjoy your new boat.
 
There's a huge amount of sense in what LangstoneLayabout says - with a slightly old but new to you boat, it would save a lot of grief to have that mast down horizontal so you could replace lights, fit new ones and maybe other kit, and above all give the rig a really good ' coat of looking at ' as my aircraft inspector friend used to say.
 
I also went up with chair, and 2 blocks (2:1). I used 2 prusik knots , starting from chair, one at the moving line which came via blocks, and the second at a tightened external halyard . Felt safe but it was tough and slow to pull down the knots for getting back.

i have 2 external halyards that go from aft to bow with 4 sheaves at masthead . 2 starboard and 2 portside. I would like to use them to make 4 internal halyarsd instead!
