: Just opened my set of plans for the Mystery (high excitement level) and I'm
: questioning whether to use my standard (1/8" radius) cove & bead
: set for this boat - or just bevel my WRC strips.

: For the Mystery, Nick suggests 3/16" hull strips and 1/8" deck
: strips. I may just up these by 10% (to 5 mm and 3.5 mm - adds 1 pound),
: but they are still substantially thinner than the normal 1/4" strips.
: Can anyone comment on the effectiveness of C&B here ?

: Also, any words of wisdom on the advantages of C&B on the various Guillemot
: hull shapes ? Some of the hulls have lots of compound curves and some have
: simpler shapes...

Putting a cove and bead on 1/8" thick strips would be hard. With care it could be done, but it would only help a little bit, and may cause alignment problems. The strips are thin enough and the deck has little enough curvature that most of the strips don't need any beveling.

On my more tortured designs, such as the Expedition Single, I find that the cove-and-bead tend to make it hard to conform to the forms. While beveling takes time, it can make it easier to get the strips to stay attached to the forms and create good, tight joints.
