An earlier lister talked about a port on his 37 cracking because of flex. I too had that problem after a somewhat rough trip up the coast. My question is "would a thicker VBR tape allow greater flexing and prevent the port breaking." I believe 1/16" tape has be been recommended. Would 1/8" tape help?
