I'm thinking of the tiller. All the ones I've seen that were laminated are done with horizontal strips. I'm thinking of going with a vertical laminate - the two outside pieces of mahogany the the center either of maple or purple heart. I'm also thinking of going to a full 1" width, with the area where it goes into the rudder trimmed down to 3/4.
I'm not worried about UV damage to the glue joints - would use a cover when not sailing. Also, my main sailboat's bowsprit was made with vertical strips of teak and holly. It lasted 30 years.
Is there something I'm missing about not going with horizontal laminates in the tiller?
