How difficult is it to fit a NASA Wireless wind with mast up ?

Thanks for all the advice, which has given me a better idea of the job and a few pitfalls to avoid... specifically not drilling through the halyards which is the kind of stupid thing I might do ?
 
My bosuns chair which I think is a Seago one has a semi rigid seat so that it does not pinch you, and it came in a fabric bag which doubles as a deep tool bag to take up with you. Its far better than a bucket as nothing will fall out of it.

I have a Seago Bosuns chair but I climb up the mast by hoisting a set of SAS rope ladders on the main halyard, which I use to ascend, with my partner using the spinnaker as a safety. The two methods allow me at the top to occasionally stand back on the steps to either get higher or to get the circulation going in my legs again !
 
I can add little - except - remember you will be drilling into aluminium and my guess is the bolts, or self tappers will be stainless unless you are using rivets.

Don't forget the Duralac (I cannot think of the best way to attach a lanyard :) ) If you forget it can be very difficult to explain to someone what you want.

No it is dead easy :unsure: you shout down to the deck hand " I forgot the F..ing duralec - stick it in the bag please & get a b..y move on because I do not want to be here all day"
You will then get a reply --which one would not care to repeat--but with luck you will haul the bag up & in it will be some duralec.
The lady in the Moody in the berth opposite will tell her husband about the uncoof yoof of today The young kids further along will have learned a couple of new words to repeat at the next meal time & all will proceed as normal.
 
Be careful not to let the drill enter too far when it breaks through, there may be light cables behind. Final alignment is via the setup menu.
Put a depth stop on the drill bit to prevent it from going to far into the mast. A couple of rounds with tape is usually good for this purpose.
