M_Boats: Hull-deck joint

My fall project is to repair all the leaks along the hull-deck joint. In Howard Audsley's blog he described taking off the toe rail and drilling out the joint before replacing the caulk (can't remember what kind). Has anyone else done this project from inside the cabin so you didn't have the work of removing the toe rail? Did it work well? What kind of tool did you use? Pam Port Townsend
