I used to have some bungee strapped to the aka but that wore through and i thought of using the ama handles but all that jib sheet dangling across the water would to me become a problem so i just added a pad eye to each aka about 2 inch outside the paddle strap, allows for good control of jib sheets and i can use the windward control sheet to reduce the slot between the jib and main, so acts a bit like a barber hauler.
I pop riveted with 5/32 aluminium rivets. The drill hole into the aka shows metal depth of about 3/16 inch so i wouldnt be too worried about the strength.
A tip if drilling into the aka, stick some masking tape over the area to drill, mark the holes with a felt pen, drill the first hole (you wont slip off the mark because of the grip of the tape) then check position of padeye and adjust second location if necessary, drill then remove tape - a perfect job!
I also have some mini tramps which attaches to itself with velcro after wrapping around the aka tightly - these tramps keep my jib sheets neatly out of the water - but the tramps are not strong enough to haul myself out on
Here are some snaps extracted from some video - i still have the bungee strap in these snaps, but has been replaced now with the padeyes for the jib sheet to pass through onto the camm cleats near my seat:
Note the jib furler in this snap - allows me to depower if necessary
Still, i dont use the jib setup in anything above 10knots and it takes doube the time to rig up with jib etc, so sometimes i just want to sail quickly and just rig up au original!!
