When two boats share the same hull type — in this case both the Tidewater Boats 1800 Bay Max 2011 and the Tidewater Boats 228WA Excursion 2011 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 Tidewater Boats 228WA Excursion 2011 measures 21,8 feet overall (2011), giving it roughly 3,7 additional feet of deck space compared to the Tidewater Boats 1800 Bay Max 2011 at 18,2 feet (2011). At 12 lbs and 28 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.
The power gap is worth calling out. Rated to 250 hp, the Tidewater Boats 228WA Excursion 2011 has a 135-hp advantage over the Tidewater Boats 1800 Bay Max 2011's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Tidewater Boats 228WA Excursion 2011 carries 9 gallons versus 4 gallons in the Tidewater Boats 1800 Bay Max 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
The Tidewater Boats 1800 Bay Max 2011 is rated for up to 5 people. Passenger data for the Tidewater Boats 228WA Excursion 2011 wasn't available.
Bottom line: The Tidewater Boats 228WA Excursion 2011 at 21,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Tidewater Boats 1800 Bay Max 2011 at 18,2 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
