Welcome!
I assume you're aware that some
parts of the PI are fairly hazardous regions, right? And from where you are now, the routes for getting a sailing vessel there are likely even more so for some
parts of the
route. Think pirates.
As to officialom, you might try the US State Department, & other
government agencies which deal with travel. Plus of course, contact the appropriate folks in the PI directly. Though be aware that what you're told, & what you encounter in real life when you get there, can differ vastly.
Also, get in touch with several yacht
delivery companies. Being sure to vet any which you're seriously interested in. But they'll have info on
delivery costs, as well as officialdom, if it's a region to which they commonly deliver
boats, or hire out captains & crew to
work in. Ditto on sailing routes,
safety, etc.
Can't help you much specificially on the
deck cargo bit. Though most likely Bing, &
Google could. At least to start. And FWIW in the last
Volvo Ocean
Race (VOR), there were some regions where the organizers had the
boats shipped as cargo, rather than have the crews sail through them, as they're just too dangerous to sail though on a high value target like a fancy yacht. And it's easy enough to check where specifically those boats got shipped to & from, as well as what the plans for the
current VOR which is about to start.
