Both the Lund 186 Tyee GL 2012 and the Lund Classic 1775 Sport 2006 are modified-V designs, the first built in fibreglass and the second in aluminium, so 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 - Lund 186 Tyee GL 2012 at 18,5 ft versus Lund Classic 1775 Sport 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Lund 186 Tyee GL 2012 tips the scales at 1 800 lbs - 790 lbs more than the Lund Classic 1775 Sport 2006 at 1 010 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 175 hp, the Lund 186 Tyee GL 2012 has a 85-hp advantage over the Lund Classic 1775 Sport 2006's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lund 186 Tyee GL 2012 carries 40 gallons versus 19 gallons in the Lund Classic 1775 Sport 2006. 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 Lund Classic 1775 Sport 2006 is rated for 6 passengers, while the Lund 186 Tyee GL 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund Classic 1775 Sport 2006 could be the deciding factor.
Bottom line: Choose the Lund Classic 1775 Sport 2006 if your priority is putting more people on the water - it handles 6 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Lund 186 Tyee GL 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
