The Hydra-Sports 2100 WA 2012 is a deep-V design and the Hydra-Sports 23 Bay Bolt 2011 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.
On paper these two are close siblings in the size department - Hydra-Sports 2100 WA 2012 at 20,9 ft versus Hydra-Sports 23 Bay Bolt 2011 at 19,3 ft. Weight tells a clearer story for trailering families: the Hydra-Sports 2100 WA 2012 tips the scales at 3 772 lbs - 772 lbs more than the Hydra-Sports 23 Bay Bolt 2011 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 250 hp, the Hydra-Sports 2100 WA 2012 has a 25-hp advantage over the Hydra-Sports 23 Bay Bolt 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 Hydra-Sports 2100 WA 2012 carries 105 gallons versus 50 gallons in the Hydra-Sports 23 Bay Bolt 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 Hydra-Sports 2100 WA 2012 is rated for 6 passengers, while the Hydra-Sports 23 Bay Bolt 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Hydra-Sports 2100 WA 2012 could be the deciding factor.
Bottom line: Choose the Hydra-Sports 2100 WA 2012 if your priority is putting more people on the water - it handles 6 passengers and at 20,9 ft it has the deck room to back that rating up comfortably. The Hydra-Sports 23 Bay Bolt 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
