Coaster
Hull Configuration and Features:
- Swedeform--widest aft of center the opposite of Fish-form
(for less wave-making resistance due to the finer angle of entry)
- Shallow V-midsection with flared sides (for a narrower
waterline and high secondary stability)
- V’ed forebody (soft ride) develops into hard chines
(resists broaching)
- Little rocker at stern, substantial at bow (for tracking
and manuverability)
- Extreme flare and reserve buoyancy at bow (resists pearling
in surf)
- Hard chine center and aft sections (carves turns and holds
an edge in breakers)
- Strong V-keel in stern quarter (resists broaching)
- Lower rear deck (easier Eskimo rolls and reduced windage
aft cuts weatherhelm)
- Higher forebody (for more foot room--to size 12--and a dry
cockpit)
- Built in knee braces (for security and control)
- Balanced wind/water couple at cruising speed (doesn’t
weathercock)
