If you can describe the setup a bit more, then some people who don't own your precise model, but have general experience, might be able to contribute to a solution.
There are several design variants for use with CB handle. One, the standard configuration on older DS1s, has the board held only on the side with the handle. The other side is, in principle free to move up and down, but because the CB trunk is narrow, the board would "wedge" itself, and effectively not be angled sideways at all.
The top part of the CB would push against the side of the CB trunk, which could flex. Possibly, if the CB got really whacked sideways (impact) you might see some cracking there. In which case a one-time repair may be all you need.
An alternative method, and one that some owners retrofitted, is where the CB pin is drilled and tapped and a bolt is used on the opposite side of the handle. That turns the whole setup into a standard pivot axle. The upside is that the CB trunk gets stressed along the plane (as the bolt wants to push up or down) but also there's some stress on the connection of CB to handle (a square hole into which fits a square pin).
I have the retrofit on my (older) DS1 and it works fine.
Finally, the CB is supposed to be supported by thwarts; short boards connecting to the top of the CB trunk from the seats. If these are missing, the whole trunk could twist w/ the CB, which also could lead to cracks. If they are missing on your boat, they need to be replaced.
