Tank capacities — where the figures come from
-
Fuel 20 gal
“A 20-gallon fuel tank” — search excerpt, practical-sailor.com · “20 U.S. gallons (76L; 17impgal)” — spec database, en.wikipedia.orgA Practical Sailor review and Wikipedia agree; no builder document was found.
-
Water 35 gal
“35 U.S. gallons (130L; 29impgal)” — spec database, en.wikipedia.orgThe only source is Wikipedia, which draws on a spec database. The class rules confirm a permanent water tank but not its size.
-
Water heater AC + engine · factory option
“Hot & Cold Pressure Water (must be ordered with shorepower or fresh water engine cooling)” — brochure (c. 1988), j35.orgThe J/35 sales brochure (printed February 1988, hosted by the J/35 class association) lists hot and cold pressure water as an option that required either 110 V shore power or fresh-water engine cooling; the standard boat has foot pumps and a 35 gal tank. A Deluxe Forepeak Stateroom package also bundled these items. No heater size given.
Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.
Thrusters and steering — where this comes from
-
Bow thruster not fitted
“STANDARD ... OPTIONS ... (full standard and option lists; no thruster)” — brochure (1988), j35.orgThe c.1988 J Boats brochure (class association copy) gives the full standard-equipment and option lists; no thruster appears in either.
-
Stern thruster not fitted
“STANDARD ... OPTIONS ... (full standard and option lists; no thruster)” — brochure (1988), j35.orgThe same builder standard and option lists used for the bow thruster offer none.
-
Steering tiller
“Varnished ash tiller with ladder style adjustable hiking stick.” — brochure (1988), j35.org · “OPTIONS ... Wheel Steering, Compass, Guard ... Elkhide Wheel Cover on Above.” — brochure (1988), j35.orgThe builder's list gives an ash tiller as standard, with wheel steering (with compass and guard) as a factory option whose make and mechanism aren't stated. The 1992 brochure's text on the new cockpit also refers to the tiller.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.

Known problems for this model
-
Balsa-cored hull and deck delamination risk hull
Both hull and deck are balsa-cored; Practical Sailor notes it has seen deck and occasionally hull delamination on 10-20 year old balsa-cored boats, so a thorough core survey is warranted.practical-sailor.com
-
Hard racing use other
Most J/35s have been raced hard, so sails, rigging and gear may need a full refit.practical-sailor.com
