Hi fellow brats...I need some good info regarding installation of a deck seat that would be removable,my husband is 84 and he insists on sitting on cooler fish box because he always holds his pole waiting for a bite that may take 10 hours for halibut, that has got to be hard on his patoosh not to mention no backrest so for Christmas I've decided to surprise him with a captain.s chair with lots of cushioning(of course he may want to stay out and fish longer!) So do they make free standing seats that you just remove like on a driftboat or with the slanted bottom on a 22' angler would I have to install a base and remove it every time we swithch to crabbing or bottomfishing as the seat would be a nuisance? thanks for any input Sue
