Glad you finally made it. The bays can be much worse than the Gulf at times. That water gets awfully skinny outside the channels. My boat draws 4.5 feet and I always wonder about going aground around the bays.
Good post, Corpus Christi bay is very shallow, averaging 7 or 8' and because it is quite large the tides effect the channels in the area very strongly.
I was heading down wind when I got into the intercoastal, but the winds were shifting just enough to send the boom to the opposite side. I discovered a real problem.
Originally this boat was manufactured with a tiller and someone later installed the steering wheel, but they placed it behind the gas tank instead in front and it put it so close (1') to the boom block and traveller so that you've got to jump around the wheel to operated it (the boom block). It's really in a bad position and my new boom end I installed saved my beacon. I'm going to remove the wheel and go back to the tiller until I decide if I'll reinstall it (the wheel) further forward.
This is why I eventually dropped the main and continued only with the jib, continuing to use the outboard to compensate a bit. In the main channel and on the bay I was still only getting 3 mph according to my GPS. With out the lazy jacks, the main is made to utilize that system, so when I did bring it down, it was really all over the place. I'd be steering away from the traffic and then jump up forward, gather up some sail around the boom and bungy it. Then steer again and go back up to the boom and do another section of it....and so on. This boom is 14' long and so is the bottom of the main, so it took 5 trips forward (in between the barge and freighter traffic) to gather up the whole sail in order to see where I was going.
Modern boats have comparatively shorter booms.
...all of this took more fuel, and made running out of gas a real possibility.
