After owning a couple of bass boats...I must recommend trying a few on for size before you drop a dime. Today's market is flooded with marketing the big 21' high performance boats with big 250's that the fella's on TV drive. Those are REALLY sweet and allow you to go on all types of water pretty safely and at GREAT speed. (They look cool too). They have almost all features that make tournament fishing a pleasure. However, they are costly to maintain. BELIEVE me when I say you can not work on those engines like we used too....They are HIGH PERFORMANCE and require a trusted mechanic to diagnose and keep maintained to stay running. Even the smaller 150, 200, & 225's are not the same old engines we used to have. You can do some minor things that can save money...but for the most part plan on bucks every year for maintenance. I am not a boat mechanic, but tried to be one on my own rig...and well, I was overwhelmed with how complicated that thing is...Looks simple but..wait.."what is that thing". The newer motors are very fuel efficient for what they do also...but comes with a price.
Almost all boat manufactures have realized we all don't have sponsors or large bank vaults full of money, and have been promoting and building a mid line bass boat that is getting into the "reasonable" price market. The new ones coming are shorter and wider with power plants that are capable of the mid 60 mph. Lighter boat, motor, and trailer combo's also equate to easier (not great) mileage, wear and tear on the tow vehicle. Earl Bentz (sp) said that the new market is the smaller boat and his line is now offering that class of boat in a wider selection. Search the brands..and see they all have them. The options and accessories are being loaded in these "affordable" rigs that make them pretty attractive.
Buying a boat that you think is adequate today...is also an issue for tomorrow. AS your skill level increases your desire to tourney fish (you gotta try just see if you get better...)goes up...you find that it would be nice to have gadget "x" to make this easier and more enjoyable...(even is something as simple as a swing away tongue for storing or retractable tie downs on the trailer not to mention automatic bilge pumps or lighted compartments, etc.).
Hey..after all that...the moral of the story is take your time...and research. I didn't, but got lucky and had some friends that helped by taking me with em in several brands...and I just paid attention to what each platform had and made mental notes of what I wanted. My goal was to tourney fish around here but still be able to afford it (I tourney fish but can't afford it...but that's a different discussion)...I still have had just a couple of trades..but ..am happy with the one I have owned for 9 years...(heck its coming back into vogue--short 19 footer with high power).
Best of Luck
