So far, my ramp tables are incomplete. I need data for public (and private commercial, boatyard) ramps: their surface (paved, gravel, dirt, sand, etc.) and tides when the ramp is useful for most trailered boats (formated like 1/3+, meaning it can be used two hours after low).
If you know this inforamtion or are close enough to check it out, I would greatly appreciate it.
