Welcome. I am your neighbor in the Houston area. We have a boat with a 6' draft that we keep in Kemah. Sailing in Clear Lake is out for us, so we just cruise down the channel the extra 5 minutes to the bay.
I can't speak to bridge clearances as thus far the only bridge we've had to deal with is the one seperating Clear Lake and the Bay. There have been no issues for us and we need 60' clearance.
I haven't looked at a C&C in person, but they do look the business as they say. There are lots of great boats in your size range and close to your price range that we inspected. If you decide to look at other boats, tell me what your must haves are and I can perhaps give you a lead on ones that we have seen personally.
