Salt is no biggie, unless you're lazy, then it'll cost you quickly and dearly.
In the same vein as yobuck, a 17' Boston Whaler Montauk can do a lot of things well. Great fishing layout for a 17'er. They float shallow but also have decent gunnel height for less than flat water.
If i could have found a nice one id probably be running one.
Down side for some (not me)would be weight and poling ability.
