Both the Polar 2310 Bay 2008 and the Polar 2700 WA 2008 are modified-V designs, both built in composite, so 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 Polar 2700 WA 2008 measures 27,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Polar 2310 Bay 2008 at 22,0 feet (2008). Weight tells a clearer story for trailering families: the Polar 2700 WA 2008 tips the scales at 6 400 lbs - 3 400 lbs less than the Polar 2310 Bay 2008 at 3 000 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 power gap is worth calling out. Rated to 600 hp, the Polar 2700 WA 2008 has a 350-hp advantage over the Polar 2310 Bay 2008's 250-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Polar 2700 WA 2008 carries 200 gallons versus 87 gallons in the Polar 2310 Bay 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 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.
Bottom line: The Polar 2700 WA 2008 at 27,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Polar 2310 Bay 2008 at 22,0 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.
