Installing bow chock

[dpfundst]

Hi,

I am considering installing bow chocks on a 2009 Carolina Skiff 198DLV.
Looking for tips, and what to watch out for.
Any tips on drilling to prevent cracking of gelcoat?
Should I use a backing to secure chock? or screws? 5200 to seal holes?
Any help is greatly appreciated.
Thanks
Dwight

Re: Installing bow chock

I would drill very slowly through the gelcoat layer. Once done there is a tool which bevels the hole out to reduce chances of cracking. I've used a large drill bit in a pinch. The top of the hole will end up being bevelled at a 45 degree as if it were were going to receive a counter sunk screw. Use a SS backing plate and bolts with nylon lock nuts. 4200 should be fine. I'm sure you will find many people who will say screws are fine. I wouldn't use them personally.

Use the countersink bit first and then drill the hole. But your chock will cover the cracks anyway.
Are you putting in cleats, or just chocks? Cleats should have backing but I don't think it's necessary for chocks for ordinary use; just use screws. Might be hard to reach up under there.

I don't think sealing the hole is very important at that location and that boat; I'd use a flexible caulk even silicone in case you have to remove or relocate them.

Also consider using the nylon chocks rather than stainless. They don't hurt as much when you stub your toe or fall on them; some of the metal ones are right sharp. Same with cleats in a traffic area. I have nylon chocks on the deck of a boat that we often board from the bow and have avoided a lot of tears. However, in freezing weather they get brittle and can break if stepped on, but no big deal; easy and cheap enough to replace. Never seen the nylon cleats break, though. I have about 16 years on 4 inch nylon cleats on my Carolina Skiff, very hard use, winter use, in boots, no problem.
