When two boats share the same hull type — in this case both the Bayliner 204 Ski N Fish 2009 and the Bayliner 217 Deck 2013 are modified vee designs with fiberglass 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?

Size is the most obvious dividing line here. The Bayliner 217 Deck 2013 measures 20,6 feet overall (2013), giving it roughly 18,6 additional feet of deck space compared to the Bayliner 204 Ski N Fish 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Bayliner 217 Deck 2013 tips the scales at 3 409 lbs — 364 lbs less than the Bayliner 204 Ski N Fish 2009 at 3 045 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Bayliner 204 Ski N Fish 2009 carries a rated maximum of 260 hp. Engine data for the Bayliner 217 Deck 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Bayliner 217 Deck 2013 carries 55 gallons versus 37 gallons in the Bayliner 204 Ski N Fish 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 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.
