Designed as a "raid-style" weekender that bridges the gap between an open sailing dinghy and a dedicated coastal cruiser, the BayRaider Expedition is a 19' 10" (6.05m) ketch-rigged trailer-sailer. Built by Swallow Yachts, it utilizes the same high-performance hull as the standard BayRaider 20 but introduces a distinctive "blister" cuddy cabin to provide overnight accommodation and protection from the elements. The model is defined by its use of modern materials—specifically a vacuum-bonded hull with an Airex foam core and standard carbon fiber spars—which keep the displacement exceptionally low at approximately 450kg to 520kg. This lightweight construction is balanced by a sophisticated water ballast system capable of taking on 300kg (300 liters) of seawater, effectively doubling the boat's weight to provide the stability of a much heavier keelboat when conditions demand.

Sailing Performance & Handling
The BayRaider Expedition is celebrated for its versatility, offering two distinct sailing personalities based on its ballast configuration. In light winds, sailing with empty tanks allows the boat to behave like a performance dinghy, capable of planing off the wind and reaching speeds of 7 to 10 knots. When the 300kg water ballast tank is filled via a simple seacock, the boat gains significant inertia and a self-righting capacity from a 90-degree knockdown. Practical Boat Owner noted that the boat can be trailed behind a small hatchback and launched in under 15 minutes, highlighting the efficiency of the carbon rig, which is light enough to be stepped single-handedly.
The yawl/ketch rig provides exceptional tactical flexibility. The mizzen sail is particularly useful for "parking" the boat head-to-wind while the skipper reefs the main or prepares the anchor. According to technical insights from the Swallow Yachts Association, the boat tracks well due to its profiled GRP centerboard and twin rudders, though some owners suggest that visibility from the helm can be partially obstructed by the sprayhood when seated low in the cockpit.
Interior Comfort & Variations
Unlike the open-cockpit BayRaider 20, the Expedition variant features a small, functional cabin. While it lacks the full standing headroom of the BayCruiser 21, it provides a "V-berth" arrangement that accommodates two adults for overnighting. The cabin is often described as a "cuddy" or "den," serving as a dry stowage area for gear or a private space for a chemical toilet.
Sibling models built on this 20-foot hull include the original open BayRaider 20, which prioritizes a massive cockpit for up to six adults, and the BayCruiser 20 (and subsequent BayCruiser 21), which utilizes a higher-volume deck molding to provide more substantial interior living space at the expense of the expansive "raid" cockpit. For those seeking the same design philosophy in a smaller package, the BayRaider 17 offers a more compact footprint while retaining the ketch rig and water ballast features.
Popular Mentions & Media
The BayRaider 20 series, including the Expedition, achieved significant acclaim when the design won SAIL Magazine’s Boat of the Year award in 2012. It has also been featured extensively in "Raid" style events across Europe, where its ability to be easily beached and rowed (thanks to its low draft and integrated outboard well) makes it a favorite for adventure racing. Editorial reviews in Yachting Monthly and Practical Boat Owner have frequently cited the model as a benchmark for the modern trailer-sailer category.
Known Issues & Buyer’s Checklist
Prospective buyers should focus on the mechanical systems that enable the boat's versatility:
- Water Ballast System: Inspect the seacock and the optional electric pump (if fitted). Over time, valves may require lubrication to ensure the tank seals properly, preventing water from sloshing and affecting stability.
- Carbon Rig UV Protection: While the carbon masts are durable and light, older masts should be checked for UV degradation of the clear coat or paint, which can lead to splintering if neglected.
- Centerboard and Rudder Pivots: The lifting foils are GRP with lead ballast in the centerboard. Check the pivot bolts for wear and ensure the lifting lines move freely without fraying.
- Outboard Well "Mylar" Flaps: The engine well uses Mylar flaps to maintain a hydrodynamic hull shape when the motor is raised. These are wear items and may need replacement if they become distorted or torn.
Community & Resources
The Swallow Yachts Association (SYA) is the primary hub for owners. It is a highly active, customer-led community that hosts technical wikis, provides rigging guides, and organizes annual "Raids" (sailing expeditions) in locations such as the Solent, the Lake District, and Brittany.
The Verdict
The BayRaider Expedition is a masterclass in compromise, offering the speed of a modern dinghy with the safety of a ballasted cruiser. It is ideal for the "adventure sailor" who prioritizes ease of trailering and the ability to explore shallow estuaries.
Pros:
- Exceptional safety with a 300kg water ballast system and self-righting capability.
- Ultra-lightweight carbon rig allows for rapid, single-handed setup.
- The ketch rig provides superior balance and easy reefing under pressure.
- High-quality vacuum-infused construction ensures a stiff, durable hull.
Cons:
- Cabin is strictly for "micro-cruising" with limited headroom and amenities.
- Sprayhood can significantly limit forward visibility for the helmsman.
- Premium price point compared to traditional glass-fiber trailer-sailers due to carbon components.
