Here is a review of the Irwin 37 with comments on their strategy, and manufacturing quality:

A couple of quotes:
”Irwin Yachts built boats of mediocre quality and finish and marketed them to buyers looking for as much boat as possible for the price.”
”Irwin Yachts was considered to have the most notoriously slipshod quality control among the larger boat builders. No other boats have as poor a reputation for warranty claims, delays in commissioning, missing or incorrect parts, and mislocated hardware as Irwin. Similarly an examination of virtually any Irwin-built boat reveals details that reflect cost savings but are problems; some, in our opinion, serious (gate valves on all through hull fittings) and some trivial (through hull fittings not installed flush with the hull).”
