Improvements for Supporting Diving from RIB

I wonder if any members can offer advice? I'm running a 7.8m Ribcraft that I use for diving and three things are causing me problems.
1. Often setting a c 50 to 70kg shot line which is a real pain (literally!) to manhandle back to the surface. What are the best options for a winch or capstan?
2. Handling these shot lines so that they don't dig in and damage the tubes makes for a lot of back strain (even using the bow lead) - does anyone have any ideas how to better manage this? I'm thinking that a stainless sleeve that can be slipped over the tubes in way of any line handling would work but wonder how others have addressed this?
3. Last but not least - ladder arrangement for boarding. The tube diameters make for some interesting gymnastics getting aboard. Anyone have any good suggestions re ladder design / sourcing?
Thanks in advance.

We used to use a system for shot handling that went on the lines of:-
Prepare the shot with the correct length of line (nothing worse than descending a shot & finding loads of slack on the bottom)
On the end of the shot rope, tie a 2m long waster line, we used 6mm blue polypropylene.
Shot your wreck.
The first diver down ties the waster to the wreck & blows the weight up on a bag. When the bag comes up, the surface party know that the shot is secure to the wreck. Rest of divers descend.
At the end of diving ops, clip the shot to the transom rings & give it a tug with the boat, the waster snaps & up comes the shot line, no trauma, no damage to boat or back.
You can adapt the system to suit your situation. If it's a deep dive, you can sent the first diver in with a 3l pony to blow the shot & save his own gas. We used to have a lifting bag permanently rigged to the shot, all the first man had to do was unroll it & fill the bag.


.....sh1t happens.......

Many thanks for the quick reply. Yes, we've been using that system too and may just have to continue doing the same but on a few occasions (for various reasons ...... ) have come unstuck and had to resort to manhandling the shot - so trying to cover that eventuality!
Thanks again.

For a cheap tube protector, try & get hold of a piece of conveyor belting.

We used to have a large buoy with a 4 inch stainless ring attached. Run the shot line through the ring, attach it firmly to the back of the boat and then gun it. As the buoy move away from the boat the it drags the shot upwards, you then need to quickly pull in the slack before the shot sinks again. I think our shot was only around 25kg.

We did have some success with an arrangement of 4 carabineers just above the shot with the mouths all facing different directions, the 4 inch ring would get caught in one and the shot would float, sometimes!!
