A Bow Pole Retro-fit
- This is a collection of photos of a bow pole which was fit onto a Cal 39. This system was made possible

locker in the bow. As it turns out, that locker is a poor place to
store heavy objects anyway!

The forestay is in the center one, and the two outside ones were designed to hold anchors.
you can see the two sleeve stiffeners riveted onto the tube. The view shows how the tabs, welded
onto the bottom stiffener, fit into one of the channels for the anchor roller. Don't be confused by the

the bow is to the right, which is different than the rest
of the photos.
is the aft end fitting for the bow pole. When the bow pole is in use this end of the pole is being
thrust down into the deck. There must be support under the deck to prevent the deck from bending
