Not a quote, appraisal, or underwriting offer. Dockage/mooring and haul-outs dominate; rig replacement is a multi-year capital event. Low fuel burn offsets higher yard time for bottom and standing rigging. Affordable used-marke

Maintenance rhythm (clear the deck)
Standing rigging visual / torque check
~12 mo · Professional survey of wire age every 8–12 years typical.
Running rigging / chafe inspection
~6 mo · Replace sheets/halyards showing core or cover wear.
Thru-hull / seacock exercise and service
~12 mo · Exercise monthly underway season; service packing as needed.
Bottom paint / haul
~12 mo · Climate and growth dependent; hard paint vs ablative strategy.
Engine oil / impeller (aux diesel or outboard)
~100h / ~12 mo · Sailboats often under-hour engines — calendar intervals matter.
Battery load test and charging system check
~12 mo · House banks age faster with solar/inverter loads.
