When two boats share the same hull type — in this case both the Fisher 17 Pro Avenger WT 2007 and the Fisher F 20 2007 are modified vee designs with aluminum 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 200 hp, the Fisher F 20 2007 has a 65-hp advantage over the Fisher 17 Pro Avenger WT 2007's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Fisher F 20 2007 carries 45 gallons versus 3 gallons in the Fisher 17 Pro Avenger WT 2007. 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 Fisher F 20 2007 is rated for 6 passengers, while the Fisher 17 Pro Avenger WT 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fisher F 20 2007 could be the deciding factor.
