Grady-White vs Boston Whaler: Which Holds Value (2026)

You have two listings open and both sellers think their boat is special. One is a Grady-White, one is a Boston Whaler, they are within a couple of feet of each other, and the Grady wants substantially more money. Every forum thread on the subject ends in brand loyalty and nobody puts a number on it. So we pulled every active Grady-White and Boston Whaler listing we track — 655 of them across 39 states — and measured what each badge actually costs and what it actually returns.

The short answer

Per foot, on an old hull, these two brands are worth the same thing.

Across hulls 25 years and older, a Boston Whaler asks a median of $646 per foot (48 listings) and a Grady-White $632 per foot (16 listings). The whole used market at that age asks $324 per foot (1,403 listings). Both badges hold about double the market floor, and they land within $14 of each other.

The difference is where they start. On hulls under 25 years old, Grady-White asks $5,956 per foot (21 listings) and Boston Whaler $4,472 per foot (67 listings), against a market median of $1,577 per foot (1,439 listings). The Grady costs more up front and has further to fall to reach the same floor.

So the honest verdict: Boston Whaler is the flatter curve, Grady-White is the bigger boat. If your priority is losing the least money, buy the Whaler or buy the Grady used enough that someone else already ate the drop. If your priority is fishing 30 miles out in a lump, that is a Grady-White argument and the depreciation is the price of admission.

What this rests on

Everything below comes from our own listing index: 445 active Boston Whaler listings and 210 active Grady-White listings, all with a real asking price, deduplicated to 432 and 207 distinct boats. 568 of the 655 are private-party, not dealer inventory. 427 of them carry a model year, which is what the age tables use.

Two limits worth stating plainly. These are asking prices, not recorded sale prices — sellers ask high and the spread between ask and sale is real. And we publish no cell with fewer than 10 listings behind it, which is why some age bands below are wide.

The price table everyone actually wants

Median asking price by hull age, both brands against the whole used-boat market:

Hull age	Boston Whaler	Grady-White	Whole market
0–9 years	$62,997 (n=73)	$136,999 (n=26)	$37,500
10–19 years	$35,900 (n=38)	$71,270 (n=16)	$19,900
20–24 years	$18,500 (n=37)	$29,500 (n=13)	$15,000
25–34 years	$15,000 (n=42)	$19,500 (n=49)	$9,500
35+ years	$9,000 (n=98)	$6,500 (n=35)	$5,900

Read the last row twice. Everywhere above it the Grady asks more — up to 2.2 times the Whaler on hulls under 10 years old. Then at 35 years the order flips, and the Whaler asks 38% more than the Grady. Narrow it further and the flip is sharper still: on hulls 35 to 44 years old, Boston Whaler asks a median $11,500 (53 listings) against Grady-White’s $6,500 (28 listings).

That crossover is the single most useful fact in this comparison, and it is also the one most likely to be misread. It is not evidence that a 40-year-old Whaler is a better boat than a 40-year-old Grady. It is mostly size.

The size trap hiding in that table

The median 25-plus-year-old Boston Whaler in our listings is 14 feet. The median 25-plus-year-old Grady-White is 22 feet. That is not a rounding difference — it is a different category of boat.

Boston Whaler has been building 13-, 15- and 17-foot boats continuously since 1958, and those small classics never leave the market. Grady-White builds 18 to 45 feet and always has, so the old Gradys on the market are 20-something-foot fishing boats. Comparing dollar medians compares a Montauk to a Sailfish.

Normalize for it and the picture changes:

Cut	Boston Whaler	Grady-White	Whole market
Under 25 years	$4,472/ft (n=67)	$5,956/ft (n=21)	$1,577/ft (n=1,439)
25 years and older	$646/ft (n=48)	$632/ft (n=16)	$324/ft (n=1,403)

Two things fall out. First, on old hulls the brands are effectively tied, and both carry roughly a 2x premium over everything else floating. Second, the newer Grady carries the larger premium — 3.8 times the market per foot, against the Whaler’s 2.8 times.

Percentage retention, meanwhile, flatters neither. Whaler keeps about 14% of its under-25 per-foot price once past 25 years; Grady keeps about 11%; the broad market keeps about 21%. That is normal premium-brand math and it is why percentage retention is a bad way to shop. What protects your money is the dollar floor, not the ratio — the same conclusion we reached measuring 33 builders in boat depreciation by brand.

What the money actually buys on each

The two brands are selling genuinely different engineering, and the price gap follows the difference.

Boston Whaler sells flotation. Every hull is built by the Unibond process — closed-cell foam injected between an inner and outer liner, bonding the two into one structure with no screws or adhesives holding the hull to the deck. A swamped Whaler floats level. Founded by Dick Fisher in 1958, the company passed through CML Group (1969), Reebok (1989) and Meridian Sports (1994) before Brunswick bought it in 1996 for $27.4 million, and it builds in Edgewater, Florida today.

Understand the limit of the claim, though. Under 33 CFR 183, every monohull powerboat built for US sale under 20 feet already has to carry flotation. Below 20 feet, Whaler’s construction is better flotation, not exclusive flotation. Above 20 feet there is no federal requirement at all, and that is where it is genuinely rare.

Grady-White sells the ride. The SeaV2 hull, a continuously variable-deadrise design, is built for running offshore chop at speed, and the boats start at 18 feet and go to 45. The company was founded in 1959, bought by Eddie Smith in 1968, and has stayed privately held and debt-free in Greenville, North Carolina ever since — a rarity in an industry mostly owned by two conglomerates. It has taken the NMMA’s Marine Industry Customer Satisfaction Index award for fiberglass outboard boats every year the award has been given.

On warranty, know what actually transfers. Grady-White’s structural hull warranty runs five years from delivery to the original retail purchaser and transfers to later owners at no cost for whatever remains of that five years, with a one-year workmanship and materials warranty alongside it. Boston Whaler’s hull terms vary by model year — read the warranty document for the specific boat rather than trusting a dealer’s summary. Either way, on the 25-plus-year-old hulls where these brands are most interesting, factory coverage is long gone and irrelevant to your decision.

What goes wrong on each

Every brand premium comes with a signature failure mode, and both of these are expensive.

Boston Whaler: waterlogged foam. The foam is closed-cell and does not soak up water on its own — but let a crack below the waterline stay wet for years and it will, and a saturated hull can carry hundreds of pounds of water you cannot see or drain easily. The check is a scale, not an eye: compare the boat’s actual weight to its published dry weight. A classic 13-footer that weighs materially more than the dry weight published for that model and year is telling you exactly what it is. A soft-sounding sole, a stern that sits low, and a boat that will not plane the way it used to are the same message.

Grady-White: wood. Grady moved to rot-resistant treated plywood in the late 1990s and to full composite transoms, stringers and decks around the 2015–2016 model years. On anything older, the transom and stringers are wood, and wet wood in a 25-year-old offshore boat is a five-figure repair. Take a moisture meter to the transom, press hard around the outboard bolts and drains, and read transom rot signs before you make an offer on a 1990s or 2000s hull.

Both brands are overwhelmingly saltwater boats — Florida, Massachusetts, California, New York and Washington account for the bulk of listings on both — so everything in buying a saltwater boat applies at full strength: corroded wiring, seized seacocks, and rigging tubes that have been wet for a decade.

Which one to buy

Match the boat to the water, then let the price table tell you when to buy it.

• You fish offshore, 20 feet and up. Grady-White, and buy it at 20-plus years old where the median is $29,500 rather than $71,270. Somebody else took the depreciation; you inherit the SeaV2 hull and a wood transom you must verify.
• You want the smallest boat that will not scare you. Boston Whaler under 20 feet. It is the one segment where the flotation is worth real money and the resale barely moves. The Montauk 17 vs 170 comparison sorts the three generations that share one name.
• You want the most boat per dollar and do not care about the badge. Neither. At 2x to 3.8x the market’s per-foot price, you are paying a premium that only pays back if you sell. Read the center console buying guide and shop condition across brands instead.
• You plan to keep it 15 years. Buy the better-maintained hull regardless of badge. Over that horizon, service history beats the nameplate by a wide margin.

What to do next

Whichever badge you land on, the order of operations is the same and the badge does not change it.

1. Weigh the age against the table above. If the ask sits above the median for that brand and age band, the seller needs a reason — new power, documented refit, low hours — and “it’s a Whaler” is not one.
2. Verify the failure mode for that brand. Scale and hull weight on a Whaler. Moisture meter on a pre-2015 Grady’s transom and stringers.
3. Check the engine separately from the hull. These hulls routinely outlive two sets of outboards, and a repower is $15,000 to $40,000+. Run the hours math in boat engine hours before you value the boat.
4. Survey it. At $18 to $30 per foot, a survey on a 24-foot Grady runs roughly $430 to $720 — see boat survey cost. Against a $29,500 boat with a wood transom, that is not a real decision.

Then negotiate against the findings, not the badge. If you want the fair-price read before you call the seller, paste the listing and get an instant verdict — Buy Score, red flags, and where that ask sits against comparable boats.
