Islander 36 - Beckson Opening Port Installation




With our boats getting to be 25 - 30 years old, the original opening ports are getting a bit tired - maybe crazed, maybe leaking or maybe just looking old. Original construction differed in the number of opening ports. Some had only two - in the head and directly across from the head. Others had four or six, adding them fore and aft of the original two.

Early in 2005, Noble Brown coordinated a fleet purchase of Beckson opening ports. Five members ordered a total of 28 ports - at a delightful price of about $60 each.

Here is a pictoral description of the replacement of the old ports aboard Vanishing Animal.

The first step is to remove the old ports. Usually they have to be literly "broken" out.
