Really useful, thanks all. I have a plan now 
I strongly recommend the type I linked over these nylon ones. The one I linked comes out straight and can be pushed against whereas these nylon ones are anything but straight and will bend rather than move forwards. I bought one first and then bought the proper one which did the job. Should have known ?I had the same problem on my boat, I bought an '20m long electricians snake' on ebay for a few £'s and it worked a treat

He'll have to bring the boat to Scotland to access the adjacent lairdPull all other halyards as tight as possible. Then drop mouse line down mast interior, If all other halyards are tight and their drop is sensible, so not crossing within the mast the you should not get crossovers.
I hope the wiring is in a conduit
Don't climb the mast - bridge, balcony, another large mast near by, dry out alongside a pier with big tides - but ideally you want the mast vertical. Take the mast out, orange against a building, house, mansion, castle - depends on your living accomodation, arrange mast to be vertical drop weight mouse line down.
The other option is to take an adjacent laird, remove with 2 mouse lines - one to replace halyard you remove and the other for the new halyard.
So much choice

A winch on a nearby boat could be used to haul the masthead down and hold it. Alternatively, if the end of the halyard is made fast to a shoreside cleat in the right place, a winch on the boat itself could be used. Yet another alternative is to use a 4-1 purchase, on the end of the halyard.No doubt in my mind that OP must get organised to remove the mast. Climbing the mast is just not possible.
I have done self righting test on my 21 fter. takes about 40 or 50kg on halyard to pull the mast to about 45 degrees from there around 30kg to hold the mast horizontal. So climbing would be crazy. Actually you won't get far up before boats loses stability and rolls so you scare yourself silly.
I would not recommend trying to feed a mouse line in while holding mast down. Just too rushed .
Look at descriptions of mast lowering on this forum. A little bit of gear and it is easy. Well worth being able to do it even if orgainsed while under way. You will always need access to mast top.
Re actually getting mouse line in. I found easiest is to dismantle fittings from mast like top and base. Always good for maintenance and corrosion protection and use existing halyards as a mouse line to take mouse line down to bottom or up to top. I do it mast horizontal. Just be careful halyards do not twist around one another. or you can use old rigging wire to feed in to mast. good luck ol'will
I do not think that you are allowed to hoist skinny kids on mouse lines any more. That stopped when gas flues came in & they did away with sweeping chimneys using kids, as they were inclined to get stuck., hoist a skinny kid up with a mouse line.
IMHO the mast of a Squib is strong enough to resist the force required to move it through 50% of 1.87m. There must have been other factors at work., for instance the end of the spreader beingpushed hard against the quay wall.I do not think that you are allowed to hoist skinny kids on mouse lines any more.

As for dropping the line from a dockside one needs to be careful. A friend of mine borrowed a Squib for an open at Lowestoft. The crew pulled the spinney halyard through the mast. So they put the boat against a pontoon & pulled the top of the mast over to the quay, using the main halyard.
The mast broke
The owner was none to pleased as it was a lightweight mast no longer available. On top of that my friend had to finish the week wearing a pink " Dick of the Week" jacket. He has since bought his own new Squib.As well as a new mast for the other Squib
At our club we lift the mast off ( 2 people) & place it against the club bridge. Then a piece of cycle chain on a length of whipping twine & much shaking normally helps.
Squib displacement is 680kg with a centre of gravity about 0.5m (estimated) below the waterline and a mast height about 8m. This would need a force of about 40kg at the masthead to heel the boat. The problem is that the Squib is fractionally rigged and pulling the main halyard puts force on the unsupported part of the mast. If he had used the jib halyard it would be pulling against the shrouds and the mast would be in compression and unlikely to break.IMHO the mast of a Squib is strong enough to resist the force required to move it through 50% of 1.87m.

An extract from Wikipedia ; "A Squib is a type of small racing keelboat designed in 1967 by Oliver Lee as a successor to the Ajax 23.[1] It is a strict "one-design" class of boat, having a length of 5.79m, beam of 1.87m, a sail area of 15.8 sq m upwind, 29 sq m total and a weight of 680 kg (including sails and fittings)"
Someone more mathematically adept than I, (or someone with more time) could perhaps work out from those data the force exerted on the masthead.
Add to that one person weighing 18 stone in the cockpit whilst the other is pulling on the mast & leverage goes quite high if the person accidentally goes on the opposite sideSquib displacement is 680kg with a centre of gravity about 0.5m (estimated) below the waterline and a mast height about 8m. This would need a force of about 40kg at the masthead to heel the boat.
