Eastern 31 2011 vs Eastern Eastern 31 2009 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Eastern 31 2011 and the Eastern Eastern 31 2009 are deep 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?

Both boats share a closely matched power ceiling — 330 hp for the Eastern 31 2011 and 330 hp for the Eastern Eastern 31 2009. 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 — 1 gal and 1 gal — so range won't be a tiebreaker here.

Both boats are rated for 9 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 Eastern 31 2011 and Eastern Eastern 31 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Eastern 31 2011 vs Eastern Eastern 31 2009 — Common Questions

Which is the larger boat — the Eastern 31 2011 or the Eastern Eastern 31 2009?
The Eastern Eastern 31 2009 is the longer of the two at 31,3 feet overall. The Eastern 31 2011 comes in at 31,3 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
How many people can each boat hold?
The Eastern 31 2011 is Coast Guard rated for 9 passengers, while the Eastern Eastern 31 2009 is certified for 9. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Eastern 31 2011 and Eastern Eastern 31 2009 share an 11 ft. 2 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Eastern 31 2011 and Eastern Eastern 31 2009?
Both boats carry similar fuel loads — 1 gallons and 1 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Eastern 31 2011 and Eastern Eastern 31 2009 from the same manufacturer?
Yes — both the Eastern 31 2011 and the Eastern Eastern 31 2009 are built by Eastern. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
