Matching a deep vee Sea Chaser 170 BR 2013 against a modified vee Sea Chaser 2100 CC 2009 means you're likely deciding between two genuinely 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 Sea Chaser 2100 CC 2009 measures 21,0 feet overall (2009), giving it roughly 4,5 additional feet of deck space compared to the Sea Chaser 170 BR 2013 at 16,5 feet (2013). Weight tells a clearer story for trailering families: the Sea Chaser 2100 CC 2009 tips the scales at 275 lbs — 121 lbs less than the Sea Chaser 170 BR 2013 at 154 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 225 hp, the Sea Chaser 2100 CC 2009 has a 110-hp advantage over the Sea Chaser 170 BR 2013's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Sea Chaser 2100 CC 2009 is rated for 7 passengers, while the Sea Chaser 170 BR 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Chaser 2100 CC 2009 could be the deciding factor.
Bottom line: Choose the Sea Chaser 2100 CC 2009 if your priority is putting more people on the water — it handles 7 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Sea Chaser 170 BR 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
