or attached to, the collar

edges of the boarding chafe system in place
• Identify the inside and outside collar HDPE
clamping bars using a method that will allow you
to put them back in the exact same locations
• Make several alignment marks that will allow you
to put the collar back in the exact same location
• Remove the screws and tab plates that attach the
collar tabs to the transom
• Remove the aluminum bow cap, four lashing “D”
rings, and fasteners
