We need a hack to get our beacons programmed to send out the all ships DSC automatically.


I would argue that it's perfectly legal provided it's only used in a case of real distress, as all means of radio communication are legal in a real distress situation.

100% agreement. And curious how it is enforced/implemented. Is it based on where the equipment is sold? In which case the hack is to order from the appropriate country. Or is it geo-fenced in the unit based on the GPS position (which gets us back to time to fix, etc.)? In which case we need a real hack, or just don't sail in those countries

When I programmed our MOB1’s in 2020, I used the web installer (not the downloadable app), and used a VPN on my laptop to connect through a server in Japan. The web installer recognized me as a user connecting from Tokyo, and allowed me to enable the all-ships DSC option. Easy. Shhh… don’t tell!

I used to ski a lot and did some alpinism when I was a student in Germany a million years ago, but never anything really technical, so I am not nearly such good friends with hanging from ropes as you are. I get everything you are saying, but what you are talking about comes only after a lot of experience, and accumulation of a lot of knowledge.

My rigger in Sweden has encouraged me to start going up the mast alone and using descenders, and this type of ascender you work with your foot, and has given me a list of gear to buy, and maybe I will do it in the new year. Instead of being hauled up on a halyard. I don't really like working up the mast, especially when the work requires both hands.

On monos we can't rig jacklines like you are talking about so the risk of going over tethered is mitigable, but not eliminable.

Agreed.


When you go up the mast, consider three things:
  • Don't let yourself get too caught up in your knitting. The system must be simple enough that you can't do it wrong. Practice going up and down just a meter until you feel right about it. You can't climb safely if you are nervous. Nerves lead to mistakes. Take you time learning.
  • When you get where you are going, secure yourself in place with a sling or rope around the top of the mast or whereever you are. It reduces swinging and improves leverage. Just as importantly, this extra anchor can calm the nerves while you work. I always carry a few spare carabiners and slings.
  • If you are using a climbing harness you may want to add wider padding to the leg loops. It's not structural, just keep the blood flowing. This REALY helps if you are up for more than retrieving a halyard. It looks odd, with duct tape, but it works fine. (I don't pad for rock climbing, only masts, where I may be hanging out for a while.)

Remember also that if you are standing, your attachment point is around a meter above deck level. So you can't use a 1m tether -- you could only just stand over the jackline. A 2 meter tether would allow you to stand and be somewhere 1 meter (or whatever the geometry is) to either side of the jackline. At the bow, where the boat is narrow, no tether you could stand up with could guaranty that you can't go over.


.
Your jacklines don't need to be at deck level, in fact if on - or near - the centre line it's better if they are not. They will be on top of the cabin/coachroof.
To see how the profs do it check out many pilot boats. The black thing is the track, you can see a pair of tethers aft stbd corner of the wheelhouse.
The pilot will normally get on or off the pilot ladder close to the bow, above the vertical fendering, while the P/B and the ship are doing about 8 knots in all weather. Seems to work.

So if you clip yourself in up there to reduce swinging and have say a heart attack how does someone get you back down?

Re: MOB on ARC.

I single-hand in mostly coastal/offshore California. In addition to a personal EPIRB, I have a floating/waterproof VHF radio attached to my Deckvest. Figure I can radio for help if I need to. Also, I have a serrated knife to cut away my tether if need to. Of course all that depends on if I am conscious and able to.

Re: MOB on ARC.

In the construction industry (UK) it's normal to use fall arrest self retracting lines.
Perhaps this would help stop the falling off the boat problem?

They look potentially great, and some even have the right hooks. Are they heavy?
