If you are willing to put salvaged material through your machinery then fine.

Besides the obvious surface nasties - shells, barnacles, bolts, nails, etc - marine poles may have hidden nasties. If you have a split or a hollow in a log, then grit or oysters or other organisms may get inside. Grit may harden like concrete. Oysters will mark but not damage your saws, grit is very hard on cutting edges. I just sharpen saw blades and use sacrificial planer/thicknesser blades. Works for me, but at non-commercial level.
