Great Loop Tool
Great Loop Boat Fit Scorecard
Compare two candidate boats against the route you actually want to run. The score is not a survey, sea trial, or insurance answer. It is a pressure test for bridge stress, shallow-water stress, docking stress, comfort, systems, and route fit.
Last reviewed: 2026-06-26. Verify all specs on the actual boat in cruising trim. Published numbers often miss hardtops, antennas, dinghy storage, canvas, davits, modified arches, and owner-installed gear.

How to use the score
The higher score is not automatically the better boat. A lower-scoring boat can still be the right choice if its weak areas are acceptable to your crew and budget. Use the category bars to decide what to verify next: measure bridge height, test docking, inspect engine access, price repairs, or spend a rainy day aboard before buying.
