When two boats share the same hull type — in this case both the Tidewater Boats 1784 2011 and the Tidewater Boats 1984 2010 are tri-hull designs with composite construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Tidewater Boats 1784 2011 at 17,3 ft versus Tidewater Boats 1984 2010 at 19,3 ft. At 11 lbs and 11 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 90 hp for the Tidewater Boats 1784 2011 and 90 hp for the Tidewater Boats 1984 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 19 gal and 19 gal — so range won't be a tiebreaker here.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
