Eastern 27 Islander 2013 vs Eastern 31 2008 — Which Modified Vee Fits Your Needs?

When two boats share the same hull type — in this case both the Eastern 27 Islander 2013 and the Eastern 31 2008 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?

The Eastern 31 2008 tops out at 380 hp. Engine specs for the Eastern 27 Islander 2013 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Eastern 31 2008 is rated for 9 passengers, while the Eastern 27 Islander 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Eastern 31 2008 could be the deciding factor.

Bottom line: Choose the Eastern 31 2008 if your priority is putting more people on the water — it handles 9 passengers and at 31,0 ft it has the deck room to back that rating up comfortably. The Eastern 27 Islander 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

The Eastern 31 2008 is the longer of the two at 31,0 feet overall. The Eastern 27 Islander 2013 comes in at 27,3 feet, making it roughly 3,7 ft shorter — a meaningful difference in deck room and overall on-water presence.

How many people can each boat hold?
The Eastern 27 Islander 2013 is Coast Guard rated for 8 passengers, while the Eastern 31 2008 is certified for 9.

The Eastern 31 2008 measures 134" wide, compared to 123" for the Eastern 27 Islander 2013. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Eastern 27 Islander 2013 and Eastern 31 2008 from the same manufacturer?
Yes — both the Eastern 27 Islander 2013 and the Eastern 31 2008 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.
