Hey popeye and OG OUTCAST,
A hearty welcome to the Hobie Forum! I have to agree with Rny about the OB vs. the BigA. But I have to add, now that I have a number of knots under my keel in my (wife's) Sport, that I would also take the Sport over the BigA for what I do in both the salt and fresh water.
I was out at Wakulla Beach some months back here on the FC in the Sport, and the first BigA I had seen hereabouts passed in the opposite direction. I was very surprised to see how little freeboard the BigA had while underway. The Sport is great, not only because of its light weight, but also because it has virtually the same cockpit layout, complete with those great gunwale tackle and gear trays, as does my OB. I have to add, however, that the much shorter length of the Sport means that it is not quite as dry a ride as the OB, but for most inshore waters around here, it's no big ting. And the Sport can't be beat for its maneuveability and ease of unloading, launching, and loading on my trailer. Just my $.02 worth.
