When two boats share the same hull type — in this case both the Lund 186 Tyee GL 2011 and the Lund 2010 Pro Guide 2012 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 — Lund 186 Tyee GL 2011 at 18,5 ft versus Lund 2010 Pro Guide 2012 at 20,2 ft. Weight tells a clearer story for trailering families: the Lund 2010 Pro Guide 2012 tips the scales at 144 lbs — 126 lbs less than the Lund 186 Tyee GL 2011 at 18 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 200 hp, the Lund 2010 Pro Guide 2012 has a 25-hp advantage over the Lund 186 Tyee GL 2011's 175-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 4 gal and 4 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Lund 2010 Pro Guide 2012 is rated for 6 passengers, while the Lund 186 Tyee GL 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 2010 Pro Guide 2012 could be the deciding factor.
Bottom line: Choose the Lund 2010 Pro Guide 2012 if your priority is putting more people on the water — it handles 6 passengers and at 20,2 ft it has the deck room to back that rating up comfortably. The Lund 186 Tyee GL 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.
