Generic Tuning Guide

1/4" Breaking Strength = 8,200 lbs
5/16" Breaking Strength = 12,500 lbs

It is suggested that the initial settings are about 10-12% of breaking strength of wire

Selden masts has a very good tuning guide

Vent stanchion

Hello all,

I need to replace my holding tank vent stanchion. Catalina Direct offers a replacement which fits a 1/2" diameter vent hose. My current vent hose and stanchion are 3/4" ID but Catalina does not seem to have that replacement. Is 3/4" standard for the Mark ll or is mine a modification?

Thanks in advance!
