Now that you've learned what styles of anchors are out there and how to attach the chain and anchor rhode, it's time to attach (or also known as "throughbolting") the anchor to the deck of the boat. Host John Greviskis shows you how.
Materials: Anchor
Anchor chocks (figure A)
Pencil or chalk (for marking holes)
1/4-20 machine screw (1/4" in diameter with 20 threads per linear inch)
Drill and bits
Countersink bit
Marine-grade silicon
Phillips screwdriver
Wrench
Washers Note: The anchor chocks are made up of four pieces (come in a set) that mount on the deck and secure the tips or points of the flukes and the shank of the anchor. - First, you'll need to find the best location on your boat for securing the anchor and chain.
- Once you've found the location, use a pencil or chalk to make a mark for the anchor chock holes. Using a drill and bit (slightly larger than the 1/4-20 machine screw -- a 5/16" bit was used for this particular project), drill the holes that have been marked.
Note: You want the holes to be slightly larger than the screw in order for everything to slide in easily. Tip: Whenever you're drilling into fiberglass, you'll need to open the topside of the hole to prevent any fracturing (also known as "spider-cracking" figure B) of the deck. To do this, be sure to use a countersink bit on the topside of the hole. - Once the holes are drilled and all the hardware is lined up, do a dry fit, which means you align everything before you actually screw the anchor chock pieces down.
- After you've completed the dry fitting and everything is ready to be screwed down, be sure to seal the drilled holes with a mildew-resistant marine-grade silicon (figure C). This will prevent water from seeping down into the deck.
- Using a Philips screwdriver, wrench and washers, tighten down the anchor chocks.
