Design and Construction
The Bradwell 18 was produced as the Mark I and Mark II, both with an LOA of 5.71m (18′ 9″), a waterline length of 5.13m (16′ 10″), and a beam of 1.90m (6′ 3″). Displacement is 544kg (1200lb) with 181kg (400lb) of ballast, and the Mark II provides 1.3m (4′ 3″) of headroom. The hull and deck are solid fiberglass, and the keel is mounted on a bolt. Writing in a period review, the boat was recognized as strong in construction, a meaningful claim for a trailer sailer routinely lifted and launched.
Rig and Handling
As a masthead sloop the Bradwell 18 carries 13.74 sq m (148 sq ft) of sail and handles with the lively feel of a good sailing dinghy. The keel allows the boat to be trailed easily and launched with minimum effort, and when towing the mast stores neatly on the superstructure while rigging is a quick and easy operation. Under way she has been proven under test to be exceptionally safe in adverse conditions, and a Practical Boat Owner review in July 2001 noted good directional stability alongside modest performance. She sits comfortably on most moorings, rounding out a practical small-cruiser package.
Accommodations
For her size the Bradwell 18 offers more than usual comfort facilities and space found in boats of comparable size, a notable trait in an 18-footer. The Mark II's 4′ 3″ headroom makes the cabin usable rather than merely vestigial, and the lifting keel's shallow draft up (0.38m / 1′ 3″) supports shoreline camping and easy recovery. The cabin volume is a deliberate part of the design brief rather than an afterthought.
Keel Arrangements and Known Issues
The Mark I and Mark II differ in keel raising arrangements. The Mark I uses a handle that protrudes through the cockpit floor, while the later Mark II relies on rope or wire for the same task. The keel bolt itself is glassed in under the cabin floor in a Mark I and is difficult to get to; it should be easier to find in a mkII. A buyer or owner should treat keel-bolt access as version-dependent, with the earlier boat demanding more invasive inspection.
The Verdict
The Bradwell 18 succeeds as a expert-designed trailer sailer that remains approachable for novices yet rewarding for cruisers. Her solid build, dinghy-like handling, and easy trailering define the appeal, while the Mark I keel-bolt access is the one clear ownership caveat.
Pros
- Strong construction in solid fiberglass
- Easily trailed and launched with stowed mast
- Sailing feel akin to a good dinghy with proven safety
- More cabin space and comfort than peers of this length
- Two versions broaden the used-market choice
Cons
- Mark I keel bolt glassed under cabin floor, hard to access
- Modest performance per Practical Boat Owner testing
