Cape Dory 28 Review — What 40 Years of Ownership Reveals

The Cape Dory 28 review I wish I’d found before buying my first one in 2004 didn’t exist. What existed were glowing magazine write-ups from 1978 and forum threads that devolved into arguments about anchor rode. So here’s the version I’d want to read — built from two decades of watching these boats sail, break, get fixed, and sell again across the New England coast where they breed like horseshoe crabs.

I’ve owned three Cape Dorys. Two 28s and a 25. I’ve surveyed half a dozen more for friends. I know exactly where the chainplates crack, which fuel tanks rot first, and why the original Volvo MD2B sounds like a diesel washing machine full of loose change. None of that means these aren’t extraordinary boats. It just means the love story is complicated.

Why the Cape Dory 28 Still Has a Following

Carl Alberg designed the Cape Dory 28 in 1970, and the bones of that design explain everything about why people are still actively sailing and selling these hulls. Alberg was a Swede trained under Knud Reimers who understood that a boat’s job is to keep you alive in bad weather and get you somewhere with reasonable efficiency. Not to win races. Not to impress people at the marina. To work.

The full keel on the CD28 runs nearly the length of the waterline. Forty-eight feet of ballasted fin keel would spook Alberg to his grave. The full keel gives you lateral resistance without drama — she tracks straight, rounds up slowly, and forgives a tired helmsman in a way that modern fin-keel designs simply don’t. The rudder hangs off the back of the keel in the traditional configuration, protected and deeply submerged. You’re not going to blow out a rudder bearing hitting a submerged lobster pot at five knots.

Cape Dory built these boats in South Dartmouth, Massachusetts from 1970 through the mid-1980s. The fiberglass layup was done with solid hand-layup construction — no coring in the hull below the waterline on most production years. That matters enormously. Cored hulls delaminate. They absorb moisture through through-hulls and deck hardware over decades in ways that are expensive and sometimes catastrophic. The CD28 hull is thick, heavy, and essentially bulletproof if maintained.

Overall displacement runs around 8,200 pounds. For a 28-foot boat, that’s substantial. Beam is 9 feet 2 inches. Draft is 4 feet 4 inches, which keeps a lot of anchorages accessible while still providing meaningful keel depth. The cabin is a surprise to anyone who hasn’t been below — the V-berth forward is genuinely usable, the main saloon seats four without contortion, and standing headroom of 6 feet makes it livable for extended passages.

The construction quality that Cape Dory maintained — consistent gelcoat thickness, quality teak trim work, solid stainless hardware — was unusual at the price point. Tartan, Bristol, and Pearson were all building comparable boats, but Cape Dory had a reputation for finishing details that held up. Forty years later, you can still find CD28s with original teak that just needs a cleaning and oil, not replacement.

These boats lasted because they were built to last. Simple as that.

Known Problems Every Buyer Should Check

Probably should have opened with this section, honestly. The reputation of these boats is so strong that buyers sometimes walk aboard, fall in love with the teak and the lines, and write a check without doing the work. Don’t do that. Here’s what actually goes wrong on Cape Dory 28s.

Fuel Tank Corrosion

The original fuel tanks are either black steel or aluminum depending on the build year, and both corrode. The steel tanks rust from the inside out after 20 to 30 years of use. The aluminum tanks pit and develop pinhole leaks, especially at the seams, when diesel with water contamination sits for long periods. Either way, the tank is typically buried under the cockpit sole and replacing it requires significant disassembly — figure $800 to $1,500 for the work if you’re having a yard do it, plus $300 to $500 for a custom-built poly or stainless replacement tank.

Check: pull the inspection plate, look at the tank walls with a flashlight and a mirror, smell for diesel contamination in the bilge, and ask when the tank was last replaced or pressure-tested. Any seller who can’t answer that question is a seller who hasn’t been paying attention.

Chainplate Stress Cracks

The chainplates on the CD28 are through-bolted to the hull liner and covered with deck-level plates that are bedded in sealant. After 30-plus years of rig tension cycling through wet-dry-wet seasons, the sealant fails. Water gets in. The fiberglass around the chainplate base develops stress cracks, and in bad cases, the backing plates inside the liner start to show delamination.

Check: remove the interior headliner panels adjacent to the shroud chainplates. Look for brown water staining, soft spots in the liner material, and any visible cracking in the laminate around the bolts. Rebuilding compromised chainplate bases runs $400 to $800 per side at a competent yard. New chainplates in 316 stainless, which you should do anyway on a boat this age, add another $200 to $400 depending on the fabricator.

Hull Blistering Below the Waterline

The CD28 hulls are old enough that osmotic blistering is common. This is not catastrophic, but it is expensive to ignore. The water permeates the gelcoat over years and creates small voids — pop them and you get that vinegar smell from the osmotic fluid inside. A moderate blister job on a 28-foot hull runs $2,000 to $4,000 depending on severity and whether the yard needs to barrier-coat after grinding.

Check: haul the boat before you buy it. Run your hand along the hull below the waterline. Blisters feel like bubble wrap under the paint. Get the surveyor to tap the hull systematically and mark any soft spots.

Volvo MD2B Engine Vibration and Reliability

The original power on most CD28s is the Volvo Penta MD2B — a two-cylinder, 10 horsepower raw-water-cooled diesel. It runs. It has run on boats for 40 years. It also vibrates so aggressively at low RPM that it walks itself off its engine mounts if you don’t check the mount bolts every season, and finding parts for it requires patience and a relationship with a specialty marine diesel shop or a Scandinavian internet supplier.

The engine mounts themselves — Volvo part number 834101 — are prone to cracking at the rubber after years of that vibration. Soft mounts don’t absorb the shaking the way a four-cylinder engine mount does because the two-cylinder firing interval is irregular and harsh. Check the mounts physically by rocking the engine by hand. Any visible cracking in the rubber or metal contact at the mount base means replacement before the next season.

Quick Inspection Checklist

Fuel tank — visual inspection and pressure test if possible
Chainplate bases — remove headliner panels, look for staining and soft spots
Below-waterline hull — haul and inspect for blistering
Engine mounts — physical check for cracking and looseness
Deck hardware bedding — especially stanchion bases and cleats, which leak onto the balsa-cored deck
Standing rigging age — any rigging over 15 years old should be replaced regardless of appearance
Keel bolts — survey should include keel bolt inspection; look for rust staining around the keel-hull joint
Stuffing box — original stuffing boxes on these boats are often original; check for drip rate and packing age

Engine Replacement Options — Beta Marine vs Kubota

Burned by a complete MD2B failure in 2009 when the raw water pump housing cracked and I didn’t catch it until the engine overheated at the worst possible moment entering Rockport Harbor in a crosswind, I spent four months researching replacement options before pulling the trigger. Here’s what I found.

The two engines that dominate CD28 repowers are the Beta Marine 14 and the Beta Marine 16, and various Kubota-based marinizations. The engine compartment on the CD28 is not enormous — roughly 18 inches of usable width and 24 inches of depth — which limits options. The Beta 14 and Beta 16 are both based on the Kubota D722 and D902 blocks respectively and fit the CD28 compartment without major surgery.

Beta Marine 14 and 16

Beta Marine engines come fully marinized with freshwater cooling, a heat exchanger, integrated raw water pump, and proper marine mounts. The Beta 14 produces 14 horsepower at 3,600 RPM. The Beta 16 gives you 16 horsepower. For an 8,200-pound full-keel boat, 14 horsepower is genuinely sufficient — hull speed on the CD28 is around 6.5 knots, and you’ll motor comfortably at 5 to 5.5 knots on the Beta 14 at around 2,800 RPM.

The Beta 14 new runs approximately $5,500 to $6,500 depending on configuration. The Beta 16 runs about $500 to $800 more. Installation labor at a yard typically adds $1,500 to $2,500 — new engine mounts, new fuel lines, new exhaust elbow and hose, throttle and shift cables, new raw water strainer. Budget $8,000 to $9,500 all-in for a clean Beta repower done right.

What you get in return is an engine that starts cold on the first compression stroke, runs without vibration that requires a chiropractor visit afterward, and has parts available from any marine diesel shop in North America. Beta’s customer support is genuinely good. I’ve called them directly about a fuel injection timing question on a Sunday afternoon and gotten a human being.

Kubota Marinizations

Some owners go directly to a Kubota industrial block and have it marinized by a local shop — typically the D722 or D902 in raw-water-cooled configuration. This approach costs $1,000 to $2,000 less than the Beta but requires finding a shop that knows marine diesel work and is comfortable with the marinization process. The raw-water-cooled versions run hotter and are harder on the engine long-term compared to the freshwater-cooled Beta, but they’re simpler and less expensive to maintain.

The Yanmar 2GM20 is also worth mentioning — a two-cylinder 18-horsepower engine that fits the CD28 compartment and has an enormous parts and service network. New they run around $5,000, and finding used ones from boat refit projects is not difficult. A used Yanmar 2GM20 with documented hours under 500 can be had for $1,500 to $2,500 and represents the budget repower option with real reliability.

What She Sails Like — Honest Assessment

Asked what a Cape Dory 28 sails like, most owners say something along the lines of “she goes to weather better than you’d expect.” That’s true and it requires explanation, because the expectation for a full-keel 1970s cruiser is that she’ll be slow and hobbyhorsy and only comfortable running downwind.

The CD28 surprises you upwind. The Alberg hull form generates less leeway than it looks like it should. In 15 to 20 knots of breeze on a close reach, she foots along at 5 to 5.5 knots and tracks without constant helm correction. The full keel acts as a damper for hobby-horsing — the pitching motion that kills speed in short chop is genuinely reduced compared to fin-keel designs. In a seaway, this matters more than almost any other single characteristic.

In light air, the limitations are real. Below 8 knots of apparent wind, the heavy displacement works against you. She needs wind to move, and she doesn’t ghost along the way a lighter racing boat does. Light air summer sailing in protected water — Long Island Sound on a July afternoon, Narragansett Bay before the afternoon breeze fills in — means motoring more than you’d like. Accept this and enjoy the days when the breeze arrives.

In rough weather, the CD28 is where the design makes its case most completely. The deep forefoot and full keel prevent the sudden lurching and rounding up that can characterize lighter, beamier boats in steep following seas. The boat stays on her feet. She’s not fast in rough weather, but she’s steady, and steady has a value that’s hard to overstate when you’re 40 miles offshore at 2 in the morning.

Comparison to the Bristol 27 and Pearson 28

The Bristol 27 is a slightly lighter, slightly shorter comparable — designed by Halsey Herreshoff with a similar philosophy but a bit more tender in a breeze. The CD28 is stiffer initially and carries her form through the heel better. The Pearson 28, a centerboard shoal-draft design from roughly the same era, goes to weather less effectively and is better suited to protected-water sailing where the shoal draft is an advantage. For offshore or coastal passage-making where the weather gets ugly, the CD28 outperforms both.

Current Market Pricing and What to Pay

The CD28 market in 2024 runs roughly $8,000 to $25,000, and the spread represents an enormous range in actual value. Understanding what separates boats in that range is the difference between a good purchase and a four-year project that consumes your weekends and your savings.

The $8,000 to $12,000 Range

At this price point, you’re buying a project. The boat is likely sound structurally — CD28 hulls rarely become genuinely unsound — but it needs work. Typical condition: original Volvo MD2B with unknown service history or known issues, fuel tank that needs replacement, standing rigging that’s well past its service life, deck hardware bedding that leaks, and cosmetics that need attention. Teak that’s been neglected for years. Old running rigging that should be replaced.

A $10,000 boat might need $8,000 to $12,000 to bring to competent sailing condition. Know that before you buy it. These are not boats you buy and sail away from the slip the next weekend without work.

The $15,000 to $22,000 Range

This is where the turn-key and near-turn-key boats live. A CD28 in this range should have a repowered engine — Beta or Yanmar within the last 10 years — new standing rigging, replaced fuel tank, and a current survey. The cosmetics should be presentable, the running rigging serviceable, and the sails adequate even if not new.

The best values in this range are boats owned by sailors who actually use them — the systems get tested, problems get found and fixed, maintenance doesn’t get deferred for five seasons. Be suspicious of boats that have sat on the hard for three or four years even at this price point. Sitting kills boats. Gaskets dry out, fuel systems gum up, and nothing substitutes for regular use.

What to Actually Pay

For a boat with a repowered Beta or Yanmar, new standing rigging installed within five years, replaced fuel tank, no blister work needed, and a survey that comes back clean on the chainplates and keel bolts — $18,000 to $22,000 is appropriate and represents genuine value for a blue-water-capable cruising boat. For comparison, a new Catalina 275 Sport lists at $65,000 and will not be sailing in 40 years.
