Hi All,

A similar question appeared on the CLC forum a week or so ago. That one involved attaching a strip deck to a S&G hull. I have had discussions with a number of people down there, and the consensus is that the sheer strips are necessary to prevent a wavy sheer. We still haven't resolved the method for the strip deck though, so any suggestions would be appreciated.

Happy Holidays

: Hi Pete,

: On a design like the Guillemot, shear clamps obviously serve no purpose. On
: designs with a realatively angular hull to deck joint, they could be used,
: but as Rob says, there are many reasons not to.

: On our designs which have an angular hull to deck joint, we use a specially
: shaped "shear strip" as shown below. This may seem like a lot of
: work, but other than running the strip through the shaper four times, it
: is really easy (especially if you do up a batch for several boats at a
: time). We generally use a harder wood (usually mahogany) to add some ding
: resistance. Since the inside is cut away, this really doesn't add any
: noticeable weight. and the inside can be easily glassed over. This strip
: is laid up with the hull. The exterior ends up being more rounded over
: than the drawing shows, due to wood removal while fairing the deck into
: the hull. Thus it ends up not much more than 1/4" thick as it goes
: around the corner. This ends up looking good, forms a strong hull to deck
: fit, and holds up well to use.
