T-tops and flyfishing
Not really much of a problem. It is worth a lot more than any potential problems. Do yourself a favor and get FULL spray curtains. You will be very happy and be able to fish in comfort on sloppy days with a minimum of rain gear, rather than covering all the way up and getting soaked on rainy and/or windy days.
Sometimes folks who are not very experienced flycasters may get messed up in rods that you have in your rocket launcher rod holders. I did it myself yesterday, but the benefits outweigh the problems by a thousandfold.
That Hydrasport is a good boat. Mu buddy here has the same one and he really likes it and it is a good ride.
