Irwin 31 Documents
Irwin 31 Marketing Sheet
Irwin 31 Spec Sheet
These are scanned PDF files of original Irwin 31 documents that came with my 1984 Irwin 31. The first is a two sided glossy sheet and the second a larger brochure. Both tout the virtues of the boat and its construction as you might expect. Useful specs. The first is about 400k and the second about 650k. Use Adobe Acrobat reader to view.
