I say go for it. I have always been just a bank fisherman untill 2 years ago when my dad bought an 18' Hewes craft. I know thats not a drift boat and I have never had the chance to try in one but it opens up your options. You don't always have to take the boat out when you fish but sometimes its nice to get away a little from everyone else.
