About the Brewer 46

Designed by renowned naval architect Ted Brewer and built by Taiwan's Mao Ta Shipyard starting in 1985, this 46-foot cutter represents classic bluewater cruising philosophy. The substantial 42,000-pound displacement and traditional long keel configuration create a seaworthy platform that prioritizes comfort and stability over pure performance. With its impressive comfort ratio of 50.41, the Brewer 46 delivers the motion characteristics serious cruisers appreciate during extended passages. The capsize screening formula of 1.56 places this design well within accepted offshore sailing parameters, while the conservative 6.50-foot draft strikes a practical balance between stability and harbor accessibility. Ted Brewer's reputation for creating robust, well-balanced designs shines through in this model's proportions. The cutter rig provides excellent sail plan versatility, allowing crews to optimize for various conditions from light coastal sailing to heavy weather offshore work. The fiberglass construction from Mao Ta Shipyard reflects the quality Taiwan builds were known for during this era. Hull speed calculations suggest comfortable passage-making capabilities around 8.23 knots, making this an ideal choice for couples or small crews planning extended coastal cruising or ocean crossings where comfort and reliability outweigh racing ambitions.

Performance Ratios
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
348.54
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
50.41
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
1.56
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 8.23 kn
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 1,820.95 pounds/inch
