Mast Slide or Gooseneck. Swivels - replaces boom guide assembly

Product Description

Mast Slide bolts to boom and accepts mast up to 1.375-inch outside diameter. Included with our spar sets and sail rigs, but offered here separately for those who want to use in conjunction with plans, or who may want to upgrade Super Snarks, Sunflowers and older Spring Creek Canoe sail rigs. The swiveling feature lets the boom swivel up without damaging anything. Closeup photo. It can even swivel the boom up all the way vertical where it and the top spar can be stored out of the way against the mast. Video: Click Here. Bolts and nuts (or sheet metal screws for Snarks) included.

Snark sailors: Please put the word "Snark" in the order comment space so we know to give you one with the correct mounting holes and hardware for the Super Snark, Sea Snark and Sunflower. Replaces Snark "boom guide assembly." This is a big improvement over anything that does not swivel vertically!

Snark and Sunflower instructions: bolt or screw the base plate to the boom. Discard left over screws, nuts and/or bolts.

We provide both sheet metal screws and bolts with nuts so you have your choice of how to attach it. You can use the existing screws that came with your boat, or our sheet metal screws, which are one size larger than original equipment in case your boom holes have become larger through wear (or in case you just want bigger screws for more strength or in case your screws have been lost).

Bolting will be more secure, but requies you to drill to make the mounting holes a little larger and to make them go all the way through the boom Only smallish holes are required, so you are not weakening the boom to any meaningful degree by drilling. Use the smallest bit that is suitable for the bolts. They are #10 bolts (3/16" approximate diameter). Please refer again to these instructions if you are a Snark or Sunflower owner when you get your item. Instructions are not sent with the item.
