The Steiger Craft 21 Deep V Block Island 2011 is a deep-V design and the Steiger Craft 26 Block Island 2010 is a modified-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.
Size is the most obvious dividing line here. The Steiger Craft 26 Block Island 2010 measures 26,0 feet overall (2010), giving it roughly 5,0 additional feet of deck space compared to the Steiger Craft 21 Deep V Block Island 2011 at 21,0 feet (2011). Weight tells a clearer story for trailering families: the Steiger Craft 26 Block Island 2010 tips the scales at 8 000 lbs - 3 300 lbs less than the Steiger Craft 21 Deep V Block Island 2011 at 4 700 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 500 hp, the Steiger Craft 26 Block Island 2010 has a 275-hp advantage over the Steiger Craft 21 Deep V Block Island 2011's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Steiger Craft 26 Block Island 2010 carries 200 gallons versus 124 gallons in the Steiger Craft 21 Deep V Block Island 2011. 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 Steiger Craft 26 Block Island 2010 is rated for 7 passengers, while the Steiger Craft 21 Deep V Block Island 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Steiger Craft 26 Block Island 2010 could be the deciding factor.
Bottom line: Choose the Steiger Craft 26 Block Island 2010 if your priority is putting more people on the water - it handles 7 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Steiger Craft 21 Deep V Block Island 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
