About the 49Er

Originally developed as a high-performance skiff for Olympic competition, this dynamic sailboat represents the pinnacle of modern racing design. Built for speed and agility, the 49er features an ultralight hull construction combined with an asymmetric spinnaker and trapeze system that allows crews to maximize boat performance in a wide range of conditions. Racing sailors will immediately recognize the boat's distinctive characteristics: its sleek, narrow beam and minimal wetted surface area translate to explosive acceleration and impressive top speeds. The demanding nature of this craft requires athletic crews with advanced sailing skills, as proper weight distribution and timing are crucial for optimal performance. Twin trapeze systems enable both crew members to hike out simultaneously, keeping the boat flat and powered up in stronger winds. While primarily designed for competitive racing, the 49er has gained recognition in sailing clubs worldwide as the ultimate platform for developing high-performance sailing skills. Its responsive handling teaches sailors precision boat control and tactical awareness that transfers well to other racing classes. The boat's reputation for durability and consistent performance has made it a fixture in sailing programs seeking to train competitive sailors at the highest level.

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
47.92
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
2.48
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. 4.94 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. 1.84 pounds/inch
