The Court 650 is a classic Australian trailer sailer that emerged from Western Australia’s prolific boating scene in the 1980s. Produced by Court Marine—a company deeply intertwined with the prominent Court family of Nedlands—the 650 was specifically designed to handle the challenging, choppy conditions of the Swan River and the open waters toward Rottnest Island. Measuring approximately 21 feet (6.5 meters) in length, it remains a staple of the used market for sailors seeking a robust, "overbuilt" pocket cruiser that is easily managed by a small crew or family.

Sailing Performance & Handling
On the water, the Court 650 is frequently described as a "dinghy with a lid," offering a responsive and lively helm while maintaining the stability required for coastal hop-overs. Its defining technical feature is a fully retractable swing keel, which significantly reduces draft to just a few inches when raised, allowing the boat to be beached or anchored in shallows that deeper-keeled vessels cannot reach. This makes it a popular choice for navigating the tidal flats and sandbars common in Western Australian estuaries.
According to editorial accounts in MySailing, the boat’s performance is notable for its sea-kindliness in fresh conditions. Unlike many lighter trailer sailers of its era, the 650 was built to withstand the "Freo Doctor"—the powerful afternoon sea breeze common in Perth—without feeling dangerously overpowered. Under standard rigging, it tracks well and offers a predictable motion in a chop. While its pointing ability is generally considered standard for a 1980s cruiser, its hull shape and ballast distribution provide a sense of security that allows it to punch through short-period waves more effectively than its flatter-bottomed contemporaries.
Interior Comfort & Variations
For a vessel of its size, the Court 650 offers a surprisingly functional interior, largely aided by its high freeboard and an innovative pop-top roof. This pop-top configuration is a critical feature, as it provides standing headroom in the main cabin when at anchor, a luxury rarely found in boats under 22 feet.
The layout typically includes a V-berth in the bow and twin settee berths in the main cabin. While original marketing materials occasionally claimed the boat could sleep up to five people, experienced owners suggest it is most comfortable as a weekender for two adults or a family with small children. The interior is purposefully simple; most models lack a built-in head or refrigerator, instead providing dedicated stowage for a portable chemical toilet and an icebox (esky). Its sibling, the Court 750, offers a scaled-up version of this philosophy for those requiring more permanent amenities and increased waterline length.
Popular Mentions & Media
The Court 650 holds a unique place in Western Australian maritime culture, often cited in discussions regarding local sailing logistics. It gained contemporary attention in the regional sailing press for its role in experimental rig modifications designed to navigate the restrictive low-clearance bridges of Fremantle. These stories highlight the boat's versatility as both a river cruiser and a capable offshore weekender for the adventurous.
Known Issues & Buyer’s Checklist
Prospective buyers should approach the Court 650 with a technical eye toward its 1980s construction methods. Key areas for inspection include:
- Galvanic Corrosion: Because these boats often utilize aluminum masts with stainless steel fittings, the interface between these dissimilar metals is a common point of failure. Look for bubbling paint or white powdering around rivets, which indicates significant wall thinning of the mast.
- Deck Core Integrity: Like many production boats of this era, the deck is a sandwich construction. "Soft spots" or delamination are common, particularly around high-stress areas like the chainplates and the mast step.
- Swing Keel Pivot and Winch: The pivot pin and the load-bearing grid for the cast iron keel are subject to significant wear. Owners often recommend drilling out and replacing old rivets or pins with 316-grade stainless steel components to prevent "clunking" or potential failure.
- Centerboard Trunk Leaks: Inspect the area where the swing keel enters the hull for hairline cracks or water ingress, as the trunk can be a difficult area to repair if structurally compromised.
Community & Resources
The primary community for the Court 650 is centered in Western Australia, with a strong presence in the Swan River yacht clubs. Technical knowledge is frequently exchanged through regional trailer sailer associations, such as the Trailer Sailer Association of WA, which remains an active repository for owner advice and historical data.
The Verdict
The Court 650 is a rugged, thoughtfully designed pocket cruiser that offers a high degree of utility for the trailer sailer enthusiast.
Pros
- Seaworthiness: Exceptional stability and handling for a boat of its size, particularly in choppy conditions.
- Pop-Top Versatility: Provides genuine standing headroom in the cabin while at anchor.
- Draft Flexibility: Fully retractable keel allows for beaching and easy trailering.
Cons
- Age-Related Maintenance: Common issues with deck core rot and mast corrosion require diligent inspection.
- Simple Amenities: Lack of built-in plumbing or galleys may feel restrictive for extended cruising.
- Size Constraints: "Five berths" is largely aspirational; it is best suited for 2-3 occupants.
