Cal 25

• Fuel unknown
  “Fuel Tanks: Total gallons: 6-10” — search excerpt, bowtosternboating.com
  Outboard-powered: the owner's guide has the outboard stowed in a cockpit locker and mounted on the transom, so fuel is a portable outboard tank, not a built-in tank. A broker spec sheet's 6-10 gal is a portable-tank range.
• Water 15 gal
  “Your CAL-25 can be equipped with a 15 gallon fresh water tank under the cockpit sole.” — owner's manual (1967), cal25.org
  The 1967 owner's guide, hosted by the Cal 25 Class Association, says the 15 gal water tank came with the optional galley package, so some boats have none.
• Holding unknown
  The 1967 owner's guide describes a marine toilet with a flush valve and no holding tank; a broker spec sheet lists a portable toilet.
• Water heater unknown
  The 1967 owner's guide describes an optional galley (15 gal fresh-water tank, icebox, stove) and an optional 12 V battery system, with no hot water or shore-power AC system mentioned, though it doesn't say none was available.

Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.

• Bow thruster unknown
  The 1967 owner's guide and the brochure standard/optional equipment text mention no thruster; neither is a complete option list.
• Stern thruster not fitted
  Our earlier figure of none has no source, and nothing was found either way.
• Steering unknown
  “Rudder Craft Inc. #CAL 25 RUD CAL 25 CAL 25 VARNISHED TILLER” — search excerpt, fisheriessupply.com
  Neither the 1967 Jensen owner's guide nor the brochure standard-equipment text names the steering. A chandlery sells a replacement Cal 25 tiller; Wikipedia gives only an internally mounted spade rudder and outboard power. No wheel option was found.

Thrusters and steering are often replaced — check the units on your boat before ordering parts.
