Large Tanks Concern- Size and Location of Carbon Canisters for Larger Capacity Tanks (93 to 170 Gallons)
36’ Tank Area (Twin 190 Gallon Tanks) Bulkheads and stringers are Foam Cored and Surround Tanks
Tanks are Inherently Insulated Tanks Located here
Poly Tanks Used in 18’ and 20’ Models Grady-White Uses Two Sizes of Poly Tanks (60 and 82 Gallon)
Smaller Models Please Note the Floatation Foam that Insulates the Tank Area 60 Gallon Poly Tank Installed in an 18’ Center Console
Completed Installation Major Concerns with New Plastic Tank Materials: • High Cost • Unproven Technologies Tank Located in this Area Under the Cockpit Floor
Reduction of Diurnal Temperature Range • Built-In Insulation and Enclosed Space • Most Larger Boats are Stored In-Water • Water Temperature has Less Daily Variation than Air Temperature • Even Trailerable Boats with Installed and Enclosed Tanks Experience a Reduced Range in Diurnal Temperature Swings
