Q1: what is a source of plans to build replacement wooden interior component for a classic 13-footer?

BACKSTORY I am doing a full restoration of my 13 classic. [This 13-foot hull] did not come with any mahogany [components]. I want to build a full interior [using] mahogany [wood].

For advice on where to find drawings of components for Boston Whaler boats that are available on-line, please see the REFERENCE section article:

For your inquiry, see the section of the above article under the heading

"Electronic Computer Aided Design Drawings for 13, 15, and 16-foot Models."

As noted in the article, draftsman Ward Grafton has drawing many that can be purchased at very reasonable prices that will provide the information you are seeking.
