When two boats share the same hull type — in this case both the EdgeWater 145CC 2013 and the EdgeWater 170CC 2009 are deep vee designs with composite 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 — EdgeWater 145CC 2013 at 14,0 ft versus EdgeWater 170CC 2009 at 16,0 ft. At 1 lbs and 17 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 115 hp, the EdgeWater 170CC 2009 has a 55-hp advantage over the EdgeWater 145CC 2013's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the EdgeWater 170CC 2009 carries 32 gallons versus 12 gallons in the EdgeWater 145CC 2013. 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 EdgeWater 170CC 2009 is rated for 6 passengers, while the EdgeWater 145CC 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 170CC 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The EdgeWater 145CC 2013 comes in at 0 lbs per hp versus 0 lbs per hp for the EdgeWater 170CC 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
