[1][3] The design was built by Columbia Yachts in the United States between 1962 and 1968, with 534 boats completed, but it is now out of production.

[3] The Columbia 24 Challenger is a recreational keelboat, built predominantly of fiberglass, with wood trim.

It has a masthead sloop rig; a spooned raked stem; a raised counter, angled transom; a keel-hung rudder controlled by a tiller and a fixed modified long keel, with a cut-away forefoot.

Back in 1963, she was $1,000 less expensive than the doghouse version 'due to substantial savings in production cost,' according to an ad of the time ... Best features: When she was first introduced, this economical and relatively roomy 24-footer would be hard to beat for value.

Worst features: The 4-berth layout is similar to the Contender 24, but simplified, with cooking gear optional.
