Because my boat is in storage, I'm asking this question online.This spring I will be pulling everything srewed-on off so I can rebed it all. As well I will be adding some new equipment. I guess that means I will have to drill some new holes. I've done a lot of reading on this subject and I think I'll be Ok. But what I do need to know is: 1) Is the cabin top cored and If so what is the Material.
2) Is the deck cored, and if so what is the material. Thanx in advance, Patrick

Not the deck. I used a very small drill and then went up one size each time I drilled until I hit 5/16" for a 1/4" hole. I had gone one size bigger so I could coat the inside hole edge with a coating of resin. I used backing plates & ss bolts, nylok nuts/washers & 3M4200 for all my additions. When the backing plates were aluminum, I made sure I had plastic material between the washer & plate plus coated the bolt shaft with liquid electrical tape. No aluminum touched the stainless steel directly.

Patrick, there is wood core where the cabin top teak is secured. There is wood core in the deck below the forward mooring cleat and all around the anchor locker, including the pump out deck fill. My deck fill hole was quite wet. It's all epoxied up now however. I also re installed it with small bolts instead of screws. I think the action of attaching and removing the pump out hose creates more strain than screws can handle.
There is wood core in the coaming aft, under the stern cleats etc. I can't remember if there is wood under the genoa fairlead tracks, however I don't think there is.
Where accessable, you can see the core from underneath. I'm fairly certain it is plywood, at least on my boat.
Whenever I encountered wood, I drilled the hole oversized, and used a small allen wrench in a drill and reamed as much wood out as I could. I duct taped the hole from below, and filled the hole with thickened epoxy. Then I redrilled the hole the correct size for the fastner.
The West System method is basically how I did/do my fastener holes.Eric [This message has been edited by Eric (edited March 15, 2005).] IP: 206.172.223.122 |

I crawled into Paradise this afternoon, since it was so sunny, to take some measurements for projects. I noticed some wood under the jib sheet cleats. I forgot to mention earlier that the wood under the forward deck extends under the pulpit as well. When I redid my holes there, I added backing plates for the pulpit flanges. My pulpit gets tugged on sometimes, so I wanted a bit of security there.
I had to use a mirror up front, in the anchor locker to see what I was doing. It's a tight space.
