Many of us have launched from Puertocitos, for me the last time was last Thanksgiving. You have to launch and retrive with the tide. Tide tables are here:

The road was very good from San Felipe, except for the last 10 miles. The road was paved at one time, but there are now big chunks of pavement missing. Take it slow, and let the tire pressure down to 25 to 30 PSI on the trailer. You can fill them back up just before you get to San Felipe.
Take the road out of town to the airport, and the only left turn before it will head you in the right direction. If you hit the airport, head back and the first right. Mission ??? the sign said. There was a checkpoint right after you made the turn.
I have also done the dirt road to Ganzaga, without a boat. It took me 4 hours, I would guess almost double that with a boat. Have a good trip.
