Rainbow 42 Buyer's Guide
Shopping the brokerage market for a Rainbow 42 means taking on a Danish-built, Frans Harter-designed performance cruiser from the mid eighties, constructed by Farsø Glasfiber A/S in solid fibreglass. At just under 42 feet overall with a 12.3-foot beam and a deep bulb-fin keel, she is a light-displacement boat aimed at sailors who value speed over volume. The buyer's task narrows to understanding the hull, the rig, and the one physical constraint that shapes every viewing.
Layouts on the Used Market
The constant across all examples is the 42-foot length, 36.4-foot waterline, and 7.64-to-7.94-foot draft dependent on load — dimensions that define the envelope but say nothing about berths or galley.
Equipment and Common Upgrades
With no equipment tiers supplied, the only buyer-consequence items verifiable from the original specification are those inherent to the build: a fractional sloop rig, a 808-square-foot mainsail-and-jib sail plan, and running rig sized to that overdriven layout. Any generator, watermaker, or navigation upgrade seen on a specific boat is an owner addition rather than a production standard, and should be judged on its own installation quality rather than assumed factory fit.
What to Inspect
The dominant physical check on any Rainbow 42 is the keel and draft configuration. At a viewing, measure the loaded draft where the boat sits — her fin with bulb draws roughly 7.6 to 7.9 feet — because that depth confines her to major marinas, and a buyer should confirm the bulb-fin keel for impact damage and verify the stated draft against the specific hull's condition. Beyond that, measure the running rig against the original guiding dimensions — halyards of 133.4 feet at half-inch diameter, 14 mm sheets with a 104.2-foot mainsheet — to see whether a prior owner shortened or undersized lines on an overrigged boat. Inspection effort belongs on keel integrity and rig correctness.
Availability and Buyer's Takeaway
Before committing, a shopper should:
- Confirm keel bulb and fin for ground impact or repair
- Measure actual draft and compare to load-dependent range
- Check halyard and sheet lengths against original specs
- Inspect rigging terminals for wear from overdriven sail plan
- Verify hull gelcoat and solid fibreglass for prior damage
