How It Works

Marina fuel typically costs 20-40% more than roadside gas stations. Diesel at marinas averages $5-7/gallon, gasoline $4-6/gallon. Idling burns about 10-15% of cruising fuel consumption. Plan for a 10% fuel reserve beyond your calculated needs — the Coast Guard recommends the rule of thirds: one-third out, one-third back, one-third reserve.
