About the ISLAND PACKET 31
Keel/CB also available. Draft - BU: 3.0'/BD: 7.0'
Designed by Bob Johnson and built by Island Packet Yachts (USA) from 1983–1989, the Island Packet 31 is a robust coastal cruiser with 262 hulls produced. Its full keel design and heavy displacement prioritize stability and comfort over speed, making it a classic example of the 'slow boat' philosophy.
- Best for:
- This boat is ideal for coastal cruisers and couples seeking a stable, comfortable platform for relaxed passagemaking, as well as single-handers who benefit from the cutter rig's manageable sail plan.
- Bluewater capability:
- With a displacement of 11000.0 lb and a low capsize ratio of 2.09, the IP31 is well-suited for offshore cruising, offering exceptional stability and seakeeping in heavy weather.
- Comparables:
- Comparable boats include the Tartan 31 and O'Day 32, which share similar full-keel, heavy-displacement characteristics and target the same market of conservative, comfort-oriented cruisers.
