Building a 16’ 8” Lapstrake Catketch to

N. G. Herreshoff’s Coquina Design

Plans by Doug Hylan

If you want to e-mail me:

I started building in 2005, and the site is a record of the progress I made since. Doug Hylan sells detailed plans and a CD with more than 500 pictures and instructions, the best reference to go to for building. In favor of the doubt I put rather many pictures onto the site. Though this may look redundant to folks who browse more for entertainment, I think seeing the same items from many different perspectives may be helpful to other builders—of course, there are always several alternative ways to get the job done, and, being no professional builder, I learn while I go, and this is what you find on the site.

If you build a Coquina, please e-mail me at I’d like to know and share.

  1. John Brooks & Ruth Ann Hill: How to Build Glued-Lapstrake Wooden Boats

  2. Greg Roessel: Building Small Boats

Both books are available at the WoodenBoat Store.

And don’t forget about Kathy Bray’s wonderful drawings of many wooden boats at

This Coquina thumbnail gives an idea about the beauty and accuracy of her artistic work; the original size print is truly amazing, as her prints of other boats:


For bronze hardware to N.G. Herreshoff specifications and in quality that matches the original, there is only one place to go to, Jim Reineck. He sells everything bronze one needs for a Coquina in a custom set and also has many more bronze items for other Herreshoff boats:
