Great Loop Pre-Purchase Checklist
A Great Loop pre-purchase checklist should not just confirm that a boat can float and move. It should pressure-test whether the boat matches the route and the crew’s temperament for months of repetitive use.
What to inspect beyond the obvious
- Actual bridge clearance and route-relevant dimensions.
- Engine access, service access, and parts practicality.
- Visibility from the helm and how line handling really works.
- Storage, heat, ventilation, noise, and rain-day livability.
A useful shortlist question
Can this boat make an ordinary bad day easier, or does it only shine on a great day at the dock?
Route-fit checks before survey
A normal survey tells you whether the boat has problems. A Great Loop pre-purchase review asks a different question: whether the boat's problems, dimensions, and daily habits are acceptable for this route. Measure air draft, draft, beam, dinghy storage, fuel capacity, water capacity, blackwater capacity, battery capacity, and engine-room access before falling in love with layout photos.
Also check the boring logistics: where filters are bought, how batteries are replaced, whether a mechanic can reach the outboard or generator, how the boat handles at idle, and whether one tired person can move safely from helm to lines.
Questions to ask the broker or owner
- What is the measured air draft in current configuration?
- What speed and fuel burn does the owner actually use for long days?
- What systems have failed in the last two years, and what was deferred?
- Can the boat be insured for the planned route, season, and crew experience?
- What would you fix before taking this boat through locks, rivers, and remote fuel stretches?
Pre-purchase mistakes
A Loop buyer can pass a survey and still buy the wrong boat for the route. The risk is falling for layout, price, or cosmetics before checking the repeated-use details that define the trip: handling, access, height, range, storage, and repair practicality.
- Do not accept listing dimensions without measuring route-critical numbers.
- Price immediate safety, maintenance, and comfort fixes before making the offer feel affordable.
- Sea trial at slow maneuvering speeds, not only at flattering cruise speeds.
- Ask whether the least experienced regular crew member can move safely during docking.
