It sounds like you are having much fun already.
But you haven't taken control of your boat yet. The previous owners always do random stuff, and it is up to each of us to rig something we understand and we are confident in. I'm glad to hear you are now busy with this task. In the case of my 1987 PSC 37, none of the previous owners had completed the cutter rig setup, and I bought it only last year... after 26 years of the baby stay and running backstays existing (pretty well uselessly). It had no tracks for the staysail sheets, no entry through the dodger, no winches, and no cleats for the sheets.
The previous owners liked it as a sloop, apparently. Your previous owners did something to keep themselves happy, but you don't have to figure out their systems; you have to have one that fits your own purposes.
After much thought and consulting with PSC I have decided not to install the staysail tracks, seeing as how they would involve 16 new holes in the roof and introduce new clutter to the walking space. Instead I have put in a pair of barber-haulers. The granny bars (mast pulpit) do not allow for any athwartship control of the sheets anyway, so the only control action on this boat model is downwards. My barber-haulers simply connect to the granny bars. From there, the sheets sneak past the dodger by going snug up against the inboard edge of the two humps that the traveler sits on. Immediately aft of that is a rope clutch leading to a special winch. Since it is too cramped under the dodger to rotate a conventional winch handle full circle, I have designed an alternate mechanism that operates more easily. Whatever your current situation is, I recommend that you complete this sort of design and construction before you leave Ecuador.
Alas, this advice appears to be too late.
Your boat seems to have a lot of stuff brought back to the cockpit. That decision is one that often gets rethought and revoked or rejiggered. The previous owners may well have left you a setup that no longer makes total sense, so don't waste too much of your brain trying to figure out how it is supposed to be used.
