It seems to be possible to put a fin designed for US depth Chinook boxes
into an European depth Chinook fin box. Is there any reason to not do
this? The reason I ask is that I now have a board w/ the latter fin box,
and I would like to use in it a fin that I had bought for the US depth
box. I tried putting said fin into the box and it *seemed* to fit
reasonably well. However, looks can be deceiving, hence the question.
