Kelp Window - Acrylic
Periscope Optics - Provides Instant Inspection of Kelp on Keel
This acrylic plug is designed to be tightly fitted through the hull somewhere forward of the keel with the round flange snugly sealed against the hull to prevent water penetration. The diagonal "eyeglass" cut of this plug inserts upward through hull and needs to face forward toward the bow so that the keel image behind it can be viewed through the "eyeglass" above the hull.
