Boston Whaler 320 Vantage

BoatVerdict market snapshot

These are asking prices. No free or public source publishes US used-boat transaction prices, so nobody — us included — can honestly show you what these boats sold for. What we can show you is what 37 sellers are asking, which is the number you are actually negotiating against.

The BoatVerdict take

• BoatVerdict listing data

  Pricing is tight: the middle half of listings sits between $200,000 and $289,000, only a 1.4x spread. A boat asking well outside that band needs a reason, and "it is loaded" is usually not enough of one.

• BoatVerdict listing data

  Supply is concentrated: our 37 listings came from only 5 states, led by FL. Expect a smaller buyer pool at resale, and budget for transport if the right boat is not local.

• BoatVerdict listing data

  Between the 2016 ($225,000 median) and the 2022 ($257,500 median) asking prices fall about 2% a year. The steepest part of that curve is behind any boat more than five years old, which is where the value sits.

• Recall (USCG/CPSC)

  13 federal recall campaigns on file touch this builder. Check the specific hull against the recall list below before you put money down; remedies are free but only if the work was actually done.

Each point is tagged with the evidence behind it. Nothing here is a claim we cannot trace back to a counted listing, a federal record, or a named analyst judgement.

What a used Boston Whaler 320 Vantage is worth

We have seen 18 distinct Boston Whaler 320 Vantage boats for sale between Jun 22, 2026 and Nov 14, 2026, model years 2016 to 2023, in 5 states. The median ask is $222,500 and half of all asks sit between $200,000 and $264,000. Asking prices fall about 8% for each year of age (34% over five years), measured on these 18 boats and steadied with the class rate.

Of the 14 listed now, 57% have been for sale for 60 days or more, counting re-posts as one boat. A boat that has sat that long usually has room to negotiate.

Engines we actually see on the 320 Vantage

• Mercury Verado / V8 FourStroke (250–400) 6 listings · 16% of our sample · median 350 hp

  Modern Mercury V8/V10 FourStroke and supercharged Verado are strong, smooth, and well-supported, a clear step up from the OptiMax era. Slightly behind Yamaha on resale trust but closing fast, and often better integrated (joystick, digital throttle).

  Service reality: 100-hour service; supercharged Verado adds the supercharger oil interval. Check for corroded battery cables and the SmartCraft harness on saltwater boats.

Boston Whaler 320 Vantage specifications

Rows marked "our listing data" are measured from listings, not published by the builder, and will differ from a brochure. Rows without a source we can name are not shown at all.

What to inspect on a used Boston Whaler 320 Vantage

1. Mercury Verado / V8 FourStroke (250–400): 100-hour service; supercharged Verado adds the supercharger oil interval. Check for corroded battery cables and the SmartCraft harness on saltwater boats. Seen on 6 of the 37 320 Vantage listings we track (typically 350 hp on this model).
2. Get the hour meter reading and divide by the boat's age. Above 150 hours a year is heavy use for a Mercury Verado / V8 FourStroke (250–400). Threshold from BoatVerdict's engine-family profile for Mercury Verado / V8 FourStroke (250–400).
3. Assume saltwater service unless the seller can prove otherwise: pull the engine cowling and look at the powerhead, check trim-cylinder rams for pitting, and open the battery and fuse boxes for green corrosion. 100% of the listings we observed for this model are in coastal states.

This list is specific to this model: analyst items for the hull, plus items driven by the engines and the regions we actually observe on 320 Vantage listings. It is not a generic pre-purchase checklist, and it does not replace a surveyor.
