Sailing a Hobie 16 solo is a lot of fun! With the weight of the crew missing you do not encounter many pitch pole symptoms. Trapezing out is kind of a requirement when sailing solo. You limit yourself to about 20 m/h of winds if you are of normal weight. With more wind you just need the extra weight.
Sheets... most people who sail solo come up with some creative way to make the jib sheet accessible from the wire. Splitting the continues line in two portions and loosely securing the ends to crew's trap wire works well. Some sailors might come up with ways to have the traveler (jib / main) control lines accessible from the wire as well.
Capsizing and trapping out... generally not a problem to unhook. Depending how low you hang from the wire you can actually stay hooked in while capsizing. You should just try to avoid falling in the sail. Capsizing happens generally pretty slow.
Pitch poling is a different story - no time to unhook there. If you do not lose the dog bone by accident, you will probably take the trap wire with you on the way forward.
Tacking... someone who can tack a Hobie 14 should be able to tack about anything
. Just let the jib backwind for a short moment, when you feel that the boat has moved securely through the tack, release the jib on the old side and sheet in on the new side. Think about learning to roll tack.
