I have modified my process since writing the book to include in inner stem. Although I did mention the possiblity of using one in my book. I do primarily because it is easier and the glassing of the ends goes better with it there. Although it probably does add some strength, I am not that concerned about it. With my plans I include a "bevel" line on the stem forms. When I make an internal stem I cut the stem form at that bevel line and replace the beveled bit with a cedar or pine piece that will stay in the boat.

The advantage of this is you have a solid surface to glue to instead of just gluing to the strips on the other side. It also saves having to make a careful joint between the strips on either side, as you can just cut the strips off flush with the end of the inner stem. Afterwards you can plane down the ends of the strip until you see the stripe of the inner stem down the middle before installing an outer stem.

When you go to glass the inside you are not faced with trying to get glass all the way down into the tight "V" of the stems, it is filled to 1/2" wide with the inner stem.

Either way works, but as of this year I prefer an inner stem. This is subject to change without notice.

: I'm getting ready to build a Cape Ann from OneOceanKayaks. The question I
: have is about adding inner stems. Looking through Ted Moores book,
: KayakCraft, he seems to be pretty adament about the need for them for
: strength. That means some additional work altering the bow and stern end
: forms to accomodate the additional dimensions as well as making the stems
: themselves. I don't mind the work if there is a benefit, I just don't know
: enough yet about these things to make an informed guess.

: I also have Nick's book and didn't see anything in there regarding inner
: stems. It seems Nick and Vaclav are pretty much in agreement and that Ted
: Moore has moved in bit of a different direction. I will put the outer
: stems on as outlined in Vaclav's manual.

: What is the general consensus here. Are the inner stems overkill or do you
: feel that it's worth the extra work to add them?

: Thanks in advance for your opinions.
