When two boats share the same hull type — in this case both the Sea Chaser 170 BR 2010 and the Sea Chaser 190 BR 2010 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?
On paper these two are close siblings in the size department — Sea Chaser 170 BR 2010 at 16,5 ft versus Sea Chaser 190 BR 2010 at 18,6 ft. At 154 lbs and 163 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 150 hp, the Sea Chaser 190 BR 2010 has a 35-hp advantage over the Sea Chaser 170 BR 2010's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 5 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 Sea Chaser 190 BR 2010 at 18,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Chaser 170 BR 2010 at 16,5 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
