Viking 35 Convertible (1974-85)

• Fuel 275 gal
  “Fuel capacity, std. 275 gal. (1,040.9 l)” — brochure (c. 1980), vikingyachts.com · “275 gallons of fuel” — search excerpt (1979), boattrader.com
  Viking's own brochure (on the builder's website, printed around 1980) gives 275 gal standard. One 1985 listing shows 310 gal, possibly a late-production or optional tank.
• Water 90 gal
  “Water capacity, std. 90 gal. (340.7 l)” — brochure (c. 1980), vikingyachts.com
• Holding 20 gal
  “a 50-gallon holding tank” — search excerpt (1979), boattrader.com
  The brochure lists an electric toilet with a holding tank but no size; one listing says 50 gal against our earlier 20. Not settled.
• Water heater standard
  “FUEL AND WATER ... Hot water heater (standard specification list)” — brochure (c. 1980), vikingyachts.com
  Viking's 35 Convertible brochure (printed c. 1980) lists a hot water heater among the standard fuel-and-water items, with pressurized water and dockside connection; no size or heating method given. Earlier 1970s boats not covered.

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

• Bow thruster not fitted
  Viking's 35 Convertible brochure (about 1980) lists standard equipment with no thruster, but it isn't a full option list, so our earlier figure of none stays unconfirmed.
• Stern thruster not fitted
  Same brochure; no thruster in the standard list, no full option list found.
• Steering hydraulic
  “MECHANICAL ... Trim tabs ... Hydraulic steering” — brochure (c. 1980), vikingyachts.com
  Builder brochure lists hydraulic steering as standard (make not stated); the flybridge is the helm station, with a pedestal helm seat.

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