Gator. I always enjoy your post sir. I started in the marine boat world at 16 yo racing smaller outboards. Evolved over the many years to using larger boats with more horsepower using mainly Alison and HydroStream hulls in circle race classes of the APBA…. and did some outboard drag boat racing as well. In 1980 went to work for a bass boat manufacturer in Arkansas. About 11 years later changed to another company that builds bass, center console and multi species boats….I still mess with and run high performance boats and stay involved in the performance boat industry to this day.
Frankly 67 isn't fast in today's marine industry as a whole. With that being said, most bass boat manufacturers have gone the trend of building longer and heavier boats ( A typical 21'bass boat will have a hull weight, less engines and interior, exceeding 2400 lbs.) This trend over the last few years has resulted in bass boat top end speeds to be much slower as compared to bass boats in previous years. The heavier weights also increase the quality of the ride and the longevity of the boats……which has become more important to the average bass angler than top end speeds. As I said in the above post, most all segments of the marine industry have products that obtain 60 plus mph……not just bass boats.
You mentioned the trend in flats boats and the pedestal bolster seats and sitting high up in those seats. The trend in the flats boats segment of the boat industry right now is building extremely light and fast boats. Many of the brands built along the Texas coast have 22'-23' boats that only weigh 1300-1400 lbs.
In comparison, that's 1200 lbs less than a typical 21' bass boat, even though they are considerably longer in length.
None of those flats boats over 20' 1" have maximum horse power ratings, so everyone is hanging high performance outboards of 300 to 500 hp on them. They can exceed the 80 mph mark in top speed (albeit most owners of them can, in no way, drive them to those speeds) and most don't adhere to any of the NMMA safety, handling or construction certification standards.
The speeds they can obtain ( in a straight line) make today's bass boats look slow…..albeit you don't dare try to turn one at those top end speeds….lest you want to come out of those high bucket seats.
