When two boats share the same hull type — in this case both the Blue Wave 170 Super Tunnel 2010 and the Blue Wave 190 Super Tunnel 2010 are tunnel 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 — Blue Wave 170 Super Tunnel 2010 at 16,6 ft versus Blue Wave 190 Super Tunnel 2010 at 18,8 ft. At 85 lbs and 11 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 Blue Wave 190 Super Tunnel 2010 has a 70-hp advantage over the Blue Wave 170 Super Tunnel 2010's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Blue Wave 190 Super Tunnel 2010 carries 24 gallons versus 18 gallons in the Blue Wave 170 Super Tunnel 2010. 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 Blue Wave 190 Super Tunnel 2010 is rated for 7 passengers, while the Blue Wave 170 Super Tunnel 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blue Wave 190 Super Tunnel 2010 could be the deciding factor.
Bottom line: Choose the Blue Wave 190 Super Tunnel 2010 if your priority is putting more people on the water — it handles 7 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Blue Wave 170 Super Tunnel 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
