Purchase price is only the beginning
Inspection, transport, lifting, registration, initial equipment and immediate work sit beside the agreed price. Record them as one-time costs before signing.
Do not treat listings as averages. Region, season, berth, size, material, age and system scope change the actual burden materially.
Annual costs as a range
Berth or storage, insurance, routine maintenance, winter service and an unplanned reserve form the recurring core. Low, typical and high assumptions are more honest than one apparently precise number.
Replace assumptions with real quotations over time. The MyBoatDesk calculator therefore preserves version, region and assumptions and remains guidance rather than a guarantee.
Account for age and system scope
Age does not increase every cost automatically, but clustered replacements become more likely. Rig, hoses, tanks, electrical, sails, propulsion and navigation have different life cycles.
A documented older boat can be more predictable than a younger boat without records. Connect every major assumption to a finding or missing information.
Reserve and purchase decision
Keep operating reserve separate from planned refit. Reserve covers surprises; refit budget covers known work. Mixing them makes the plan look safer than it is.
Compare candidates with the same categories and time horizon. Only then can a higher price be weighed against better condition, documented replacements or suitable equipment.
