The Coastwise Cruiser, designated as Design No. 675 by the legendary naval architect John G. Alden, represents a pivotal moment in the transition from bespoke racing yachts to standardized, seaworthy offshore cruisers. Introduced in 1938, the model was primarily constructed by Graves Yacht Yard in Marblehead, Massachusetts, a facility already esteemed for its high-performance racing dories. The Coastwise Cruiser was marketed as a "packaged" yacht that provided the elegance and balance of an Alden design with the structural integrity of Graves’ traditional New England craftsmanship. Built largely of Philippine mahogany over white oak frames with cedar or mahogany planking, these vessels were intended for owners who demanded a boat capable of handling the unpredictable conditions of the Atlantic coast while maintaining a refined aesthetic.

Sailing Performance & Handling
The Coastwise Cruiser is defined by its full keel and heavy displacement, characteristics that provide exceptional directional stability and a comfortable, "kindly" motion in a seaway. With a length overall of 36' 5" and a waterline of 26', the hull features the signature Alden "clipper" bow and a graceful sheer line that helps keep the deck dry when punching through a chop. The design typically carries a sail area of approximately 645 square feet, which, when paired with its 5' 3" draft, allows it to track reliably upwind without the "skittishness" associated with modern fin-keel designs.
Handling is often described by owners as deliberate and powerful. According to historical records maintained in the John G. Alden Design Archives at the MIT Museum, the 675 was engineered for "ease of handling by a small crew," often featuring a fractional sloop rig that balances the helm effectively under reefed sails. While the Coastwise Cruiser is not a light-air specialist, it excels in 15–25 knots of breeze, where its momentum and well-ballasted hull allow it to maintain speed through heavy swells that would stall lighter boats.
Interior Comfort & Variations
Designed for extended coastal passages, the interior of the Coastwise Cruiser reflects the practical luxury of the pre-war era. The standard layout features a traditional four-berth configuration: two settee berths in the main cabin and a dedicated V-berth forward. The use of mahogany joinery throughout, a hallmark of Graves Yacht Yard, creates a warm, sturdy environment that avoids the "plastic" feel of later production boats.
The galley is typically located aft, flanking the companionway to ensure ventilation and proximity to the cockpit for the cook. Variations in the interior often depended on the original owner's specifications, as Graves was capable of semi-custom modifications. Some hulls were fitted with a slightly more open "day sailer" cabin profile, while others prioritized a fully enclosed head and additional hanging lockers for longer voyages. Headroom is generous for a boat of this vintage, hovering around 6' 1" in the main cabin, a feat achieved by Alden’s clever use of a cambered trunk cabin roof.
Popular Mentions & Media
The Coastwise Cruiser maintains a storied presence in American maritime history, frequently appearing in the "classic" divisions of prestigious East Coast regattas. The model's cultural footprint is bolstered by its inclusion in the MIT Museum’s maritime collection, which preserves the original lines and construction offsets for Design No. 675. This preservation has allowed modern shipwrights to accurately restore surviving hulls, ensuring the model remains a fixture at events like the Marblehead Classic Yacht Regatta.
Known Issues & Buyer’s Checklist
Purchasing a Coastwise Cruiser today is an exercise in wooden boat stewardship. Buyers should focus on several high-signal technical areas common to Graves-built boats of this era:
- Fastener Fatigue: The original bronze or galvanized fasteners may have reached the end of their lifespan. A survey should include "pulling" a few fasteners below the waterline to check for "pinking" (de-zincification) or significant wasting.
- Iron Ballast Keel Bolts: Many Alden designs utilized iron ballast. If the keel bolts have not been replaced in the last 20–30 years, they are prone to internal corrosion which can lead to "the smiles"—a gap appearing between the wooden deadwood and the ballast keel.
- Deck Core and Canvas: Many Coastwise Cruisers originally featured canvas-covered wooden decks. If the canvas has been breached, freshwater rot in the deck beams and sub-decking is almost certain. Inspect for soft spots around the chainplates and the base of the mast.
- Rudder Post and Horn Timber: The area where the rudder post passes through the horn timber is a notorious spot for rot in full-keel wooden boats. Ensure the wood is firm and that the rudder port stuffing box is not weeping excessively.
Community & Resources
Owners and enthusiasts of the Coastwise Cruiser benefit from a dedicated network of classic yacht organizations. The most prominent resource is the Alden Design Registry, which attempts to track the provenance and current status of all John Alden designs. Technical support and historical documentation can be sought through the Marblehead Boatyard Associates, the successor entity to Graves Yacht Yard, which still operates on the historic Little Harbor site. For those seeking original blueprints for restoration, the MIT Museum Hart Nautical Collections serves as the primary technical wiki for the model.
The Verdict
The Coastwise Cruiser is a quintessential "gentleman’s yacht" that offers a bridge between the Golden Age of sail and the practical needs of modern classic enthusiasts.
Pros:
- Timeless Aesthetics: The Alden lines and Graves craftsmanship are universally admired in any harbor.
- Seaworthy Motion: Exceptional stability and tracking in heavy weather.
- Historical Value: Significant provenance and eligibility for exclusive classic yacht regattas.
Cons:
- High Maintenance: As a wooden vessel, it requires an annual commitment to varnish, paint, and structural monitoring.
- Aged Systems: Original plumbing and electrical systems often require complete modernization for safe cruising.
- Niche Market: Resale is limited to buyers with the specialized knowledge or budget required for wooden boat care.
