Hi Jim,
I had responded to an earlier post of yours. Sorry we weren't able to connect. We are in the Port Isabel/South Padre Island area, and enjoy boating and sailing here... more options than the Port Mansfield area, IMHO. I would enjoy sharing local information with you, but we are heading out in the morning for some extended cruising.
A couple years ago, I scoured the area, trying to get a look at a C-Dory. Couldn't find a thing. Judging from the comments and gawkers we get, there is certainly a market for this boat in this area. There is someone on the Brat Map that has a TC listed in Port Isabel, but we have never come across it.
If you've been in the area the last 6 days, the weather is not typical. We get an occasional norther that blows in during the winter, that is usually a 2-3 day event. This one has been nasty (though nothing like they've been getting north of us). Average daytime high in January on the coast is 70º. Haven't seen that since last week. :xseek And not looking great for the next week.
The C-Dory is a great boat for this area. When we pulled out yesterday, it was in the 40s and drizzling. While not big fun at the ramp (washing the boat/trailer down in the precip), the boating itself was decent (thanks in large part to the Wallas).
If you come to this part of the coast, you will find excursion boats that do bay trips as well as off-shore fishing. Large ship traffic into Brownsville; barge traffic along the ICW. Scads of small fishing boats. Dolphin watch boats. Sailboats playing in the breeze. Skinny water in the bay, deeper in the channels, good access to the Gulf. And the C-Dory is comfortable in all that. In a previous post you had mentioned river cruising - the closest for that would be the Arroyo Colorado, navigable from the ICW to the Port of Harlingen (about 26 miles); there are some ramps along the south side of the river in the Arroyo City area. The river runs along the Atascosa Wildlife Refuge; plenty of birding and wildlife viewing there.
Pick up a Hot Spot fishing chart for the lower Laguna Madre to get an idea of the water around here (NOAA charts are almost non-existant). The depths are well marked on the chart.
Bring Pandy Girl on your next trip. The Expressway through the Valley can be a bit of a zoo, but you will enjoy the boating available on the coast.
Best wishes,
Jim B.
