In the right of the picture, you can see the folding aluminium ladder I have been using. This was on the boat when I bought it and has simply been used like that ever since. It also gets used to climb down the outside of Lady Jane, onto the platform, from time to time.
Right now the ladder is simply propped there, with no support or fixings of any kind to keep it in place, obviously not too safe a state of affairs.
While I'm fine with using the ladder for myself, I'm very concious of the safety of other people using it, and I'm also aware of the potential for an accident when I'm tired, or not concentrating.
The bottom of the hold is about three metres (9 ft) below the deck, so any fall is likely to be troublesome, especially if I'm on the boat alone.
I think some lengths of angle iron, with angle iron steps should do it. I can then weld the top of the ladder to the hatch entrance, and pin the bottom to the concrete in the hold using Hilti nails.
While I'm on the subject, it had occurred to me that the open hatchway is a big space just above deck level, and one which can be fallen through very easily.
I should also make up some kind of safety grill to go into the hatchway. One that people could climb through easily enough, so it could always stay in place unless anything bulky needed lifting or lowering.
