I decided that the mast step would not have a lot of forces being applied horizontally since it isnt very high. So I didnt do any there. but I figured the daggerboard housing might be a weak spot. if for no reason that it is going to be used as a support when getting up and down. since it sets well above the contact point there could be a lot of leverage acting on the joint when some one leans up or pulls on it. so I added a small fillet to that base, but not anything nearly as big as what is used for the bulkheads. it also sort of cleans up the look a bit down along that edge.

I'm pretty sure CLC has said there can be  healthy lateral loads on the dory mast step so I did small fillets on the outside of the mast step, and even got some on a stick and did a small fillet on the inside...I also cut the aft lower corner off for water drainage so thought small  fillets would be a cant hurt, might help type thing.
