Tank capacities — where the figures come from
-
Fuel 20 gal
No builder or owners' association document could be checked. Spec sites repeat 20 US gal (76 L). A 1982 broker listing contradicts itself: 15 gal in its text, 20 gal in its table. A forum owner had an 18-gal replacement tank made by the original tank maker.
-
Water 60 gal
No builder source was found. The same 1982 listing says two 35-gal tanks in its text but 30 gal in its table, so it settles nothing.
-
Holding unknown
Only one listing gives a figure (15 gal in its text, 24 gal in its table), and it contradicts itself, so it wasn't used.
-
Water heater unknown
Practical Sailor's used-boat review says a shower grate was standard but pressure water was an option; it does not mention a water heater.
Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.
Thrusters and steering — where this comes from
-
Bow thruster not fitted
No source mentions a thruster, so our earlier figure of none has no source.
-
Stern thruster not fitted
Nothing was found either way; our earlier figure of none has no source.

Steering varies by year · Edson
“The Cape Dory 30 was originally equipped with worm gear steering. This type of gear is powerful, foolproof, and requires” — review, practical-sailor.com · “With the cutter rig, it became feasible to put a more conventional pedestal steerer in the boat.” — review, practical-sailor.com · “Our choice in a Cape Dory 30 would be a latemodel cutter with full-width galley, Edson pedestal” — review, practical-sailor.com · “Baldwin's note records that "tiller or wheel steering available," and both turn up” — spec database, passageboats.com · “CLASSIC PEDESTAL STEERER/TAPERED ... CHAIN & WIRE ROPE KIT W/HARDWARE ... BRONZE QUADRANT” — spec database, edsonmarine.comSteering changed over the run: early boats, especially the ketch, had a worm-gear wheel steerer aft with no pedestal (a geared type, not mechanical), while later cutters took an Edson pedestal with chain-and-wire to a bronze quadrant (Edson's Cape Dory 30 data sheet). A secondary source says a tiller was also offered; the change year wasn't found.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Offered as masthead ketch (30K) or cutter (30C). Lead ballast inside the keel. Chainplates are cast bronze lugs; deck hardware and seacocks by Spartan. The later Cape Dory 30 Mk II (1987-1990, Clive Dent design) is a different boat.
Engines fitted
-
Volvo Penta MD7A (with Walter V-drive) — 13 hp, diesel, single
standard
Beta Marine's repower guide says most CD30s have a Volvo MD7A with a close-coupled Walter V-drive; owners on SailNet and the Cape Dory board describe the MD7A in their CD30s. The 13 hp figure is the MD7A's usual rating (quoted by a Cape Dory owner for the same engine), not stated specifically for the CD30.Sources: betamarineusa.com · sailnet.com · capedory.org
-
Beta Marine Beta 16 (with ZF 15 MIV V-drive) — 16 hp, diesel, single
common repower
Beta's most-used replacement; a Beta 20 fits the cutter version only. Owners also discuss repowering in the 18-27 hp range.Sources: betamarineusa.com · capedory.org

Known problems for this model
-
Hull-deck joint not through-bolted; no backing plates on some hardware hull
Practical Sailor notes the hull-to-deck joint relies on a bonded putty joint with only stanchion and chainplate bolts through it, and stanchions have washers rather than backing plates.practical-sailor.com
-
Head sink, shower and icebox drain to the bilge plumbing
Original plumbing drains the head sink, shower and icebox into the bilge; owners commonly add a sump pump. Early boats also had split water tanks plumbed separately to galley and head.practical-sailor.com
-
Balsa-cored deck deck
Solid hull with balsa-cored deck; nonskid discoloration was the main deck complaint in the owner survey.practical-sailor.com
Steering
Edson — Pedestal chain-and-wire steering parts: good
Edson (New Bedford, MA) still sells service parts: chain-and-wire kits, sprockets, idlers, pull-pull conduit steering and internal pedestal parts, and keeps steering data sheets by boat model, many decades old.
Parts sources: Edson Marine (service parts)
Common problems (3)
-
Old or slack steering wire steering
Edson advises replacing steering wire about every five years, checking tension with the wheel locked, and inspecting under load annually; owners often find decades-old stiff wire.usna.edu · youtube.com
-
Lubrication and fastener checks steering
Chain, wire, sheaves and pedestal bearings need regular oiling or greasing, and clevis/cotter pins and bolts should be checked monthly to avoid failures.usna.edu
-
Replacing engine control cables in the pedestal steering
Swapping throttle/shift cables inside an Edson pedestal is a common owner job requiring removal of the wheel shaft sprocket pin.forums.sailboatowners.com
Edson — Traditional geared steerers (worm / rack-and-pinion) parts: good
Edson says its traditional wheels and geared steerers are still available, now built with modern materials; rack-and-pinion steerers are offered for transom-hung and inboard rudders.
