That is dandy, if you can *find* an affordable piece of mahogany in the required size. I spent weeks trolling not only big box stores but individual lumber suppliers and prices I got quoted sometimes approached the value of my entire boat, one the shipping was included. ?I was bout to give up and make one from oak with a ? fiberglass outer sheath, when I found an affordable, damaged mahogany rudder on eBay and fixed that up instead.
