When two boats share the same hull type — in this case both the Lund 186 Fisherman GL 2012 and the Lund SSV 18 Tiller 2007 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 Fisherman GL 2012 at 18,5 ft versus Lund SSV 18 Tiller 2007 at 18,0 ft. At 18 lbs and 46 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 175 hp, the Lund 186 Fisherman GL 2012 has a 115-hp advantage over the Lund SSV 18 Tiller 2007's 60-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: Performance buyers should lean toward the Lund 186 Fisherman GL 2012 and its 175-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund SSV 18 Tiller 2007 with its 60-hp rating is the more economical daily driver.
