These are published prices from other businesses, not DockDash prices. Your quote may differ: condition, access, what’s included and “starting at” pricing all move the number.
How this works
- Per-foot prices: published rate × your boat length = price per visit. We do this for the lowest and highest published rate that fits your boat.
- Per year: price per visit × visits per year. Hourly rates have no yearly figure, because the hours depend on the job.
- What fits your boat: where a business published separate sail and power prices or size tiers, only the matching one counts.
- Region: if fewer than 3 published prices fit in your region, we use all of California and say so.
- Median: the middle business, with each business counted once.
- Money is computed in whole cents. Nothing you type leaves your browser; we remember your inputs on this device only.
Length overall vs waterline
Most per-foot prices are multiplied by the boat’s length overall (LOA): bow to stern, often including pulpits, swim platforms and davits. A few businesses use waterline length, which is shorter, so the same rate gives a smaller bill. Before comparing two quotes, ask each business which length it bills on and convert both to the same basis.
Many price lists also change the rate with size: a higher per-foot rate for bigger boats, or a flat minimum for small ones. Where a business published tiers, the tables below show each tier separately.
