When two boats share the same hull type — in this case both the Lund 186 Tyee GL 2007 and the Lund 1900 Pro-V SE 2009 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?
The power gap is worth calling out. Rated to 225 hp, the Lund 1900 Pro-V SE 2009 has a 50-hp advantage over the Lund 186 Tyee GL 2007's 175-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 1900 Pro-V SE 2009 carries 45 gallons versus 4 gallons in the Lund 186 Tyee GL 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
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: Performance buyers should lean toward the Lund 1900 Pro-V SE 2009 and its 225-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 186 Tyee GL 2007 with its 175-hp rating is the more economical daily driver.
