The Eastern 20 2012 is a modified-V design and the Eastern 31 2012 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The power gap is worth calling out. Rated to 330 hp, the Eastern 31 2012 has a 240-hp advantage over the Eastern 20 2012's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Eastern 31 2012 carries 100 gallons versus 40 gallons in the Eastern 20 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Eastern 31 2012 is rated for 9 passengers, while the Eastern 20 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Eastern 31 2012 could be the deciding factor.
