The Blue Wave 170 Classic 2004 vs Blue Wave 180 T Special 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
The power gap is worth calling out. Rated to 115 hp, the Blue Wave 180 T Special 2005 has a 35-hp advantage over the Blue Wave 170 Classic 2004's 80-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 Blue Wave 180 T Special 2005 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Blue Wave 170 Classic 2004 with its 80-hp rating is the more economical daily driver.
