While the original inquiry is quite old, for those pondering the question, one of our close friends that was sailing his Bene 42 in the EC for many seasons used to lay the boat up on the hard in Trini until a few seasons ago. He switched to using Antigua
(Jolly Harbor) as he reported that the crime situation in Trini had become untenable.
More recently, other friends of ours with close and extended family
in Trini returned home after this last Christmas
to report that while there they felt like they were imprisoned. Their family
there had walled off their property, installed iron bars on all the windows and doors, had had their cars "armored"; and, kept armed guards around their home 24/7/365 and with them when any of them traveled about during the day. They felt they could not safely leave their family's compound before sun up nor after sun set. Evidently, there is/was a lot of "spill over" ex-pats from Venezuela
and an excess of "street people" and attendant violent crime problems. Trinidad was once a lovely place but, given the foregoing, I would not consider going there even remotely as one is not immune even in "secure marinas/boatyards".
