Beneath that period styling is a solid-fiberglass hull with 3,870 pounds of ballast and a displacement of 8,600 pounds. The resulting .45 ballast ratio helps explain how well she stands up to weather.
Design and Construction
Grampian Marine built the 30 with a strong, hand-laid, solid-fiberglass hull. The deck-to-hull joint was lapped over an internal flange, then sealed, bonded, and mechanically fastened. Large, flat deck panels were stiffened with end-grain balsa block, a sensible 1970s solution when materials were inexpensive.
The main bulkhead is bolted directly to the port-side cap-shroud chainplate. Every other chainplate is secured to built-up fiberglass tabs molded into the hull. That exception matters: the bolted bulkhead conceals a weakness the other chainplates don’t share.
Rig and Handling
The standard rig carried 390 square feet of sail at 100 percent, including a 190-square-foot mainsail and a 143-square-foot working jib. The #1 genoa measured 340 square feet.
Boats ordered with the tall-rig option received a taller mast and shorter boom, raising the sail plan’s center of effort. Tall-rig sails won’t fit a standard-rig boat, an important detail when shopping for used canvas.
Writing in Cruising World, reviewers found the boat stiff and dry even in centerboard form. On a close reach, she balances well enough to track for hours without a hand on the tiller. She won’t outpace or outpoint modern designs, but several hulls have completed long bluewater passages. One was sailed single-handed to Bermuda twice, through the Panama Canal to California, and righted herself immediately after a knockdown off Venezuela.
Accommodations
Below, the Grampian 30 offers 6 feet 4 inches of headroom and a conventional layout that uses the beam well. To port is a large, long quarter berth that makes a fine sea berth. To starboard, the L-shaped galley includes an icebox accessible from both the galley and the cockpit.
The dining table drops to convert the U-shaped settee into a double berth. It also holds charts and doubles as the chart table. The starboard settee is the only berth where someone over six feet may feel cramped.
Forward of the saloon, a small head sits to port, opposite a hanging locker with a shelf. The bow cabin has a long, wide V-berth, along with bins, drawers, and shelves. Large portlights keep the interior light and airy. Five berths are standard, with an optional sixth.
The cockpit is long enough for a tall person to stretch out. With the tiller hinged up, it can seat several people comfortably.
Known Issues
The two 1-inch cockpit drains are adequate for rain but a little slow for a boarding wave, so water coming over the side can linger.
The port-side cap-shroud chainplate is a more serious concern. Because it bolts to the main bulkhead rather than to a molded tab, a leak around the chainplate can soften the bulkhead. The damaged area remains hidden beneath the fiberglass tabbing.
The original aluminum stemhead fitting should be replaced with stainless steel, and the bedding around the portlights may need renewal. Access to the forward half of the engine is good, but the transmission and stuffing box are difficult to reach without cutting into the cockpit sole.
Refits and Ownership
Owners have made a variety of practical upgrades over the years. Some replaced the two-burner alcohol stove with a model that includes a full oven, while others added refrigeration to the icebox. A few boats were converted to wheel steering.
Many owners fitted backing plates to the chainplates attached to the hull tabs. Where access to the transmission and stuffing box proved inadequate, some cut a watertight hatch into the cockpit sole. On some boats, the cockpit drains were enlarged or supplemented with additional drains.
The Verdict
The Grampian 30 is an honestly built small cruiser with the seakeeping character of a larger boat and a layout that still works for coastal cruising and occasional offshore use. Its main structural caveat is specific and manageable: keep an eye on the port chainplate and bulkhead, and regard the aluminum stemhead as a replacement item.
She isn’t fast by modern standards, but she is steady, dry, and forgiving.
