Hi,
Great looking boat. I have a question: I want to add up to a 150% Genoa to my Mac25. Where did you place your Genoa Tracks? Did you have to add backer blocks? Did you have to sleeve your side cables (standing rigging) that run to the mast? Has anyone gone to a Masthead Genoa/Jib instead of the fractional jib? My thought on the latter was that the added center of effort towards the front of the boat would balance the rear heavy condition we normally have. (I could have this last part wrong, the balance is probably side to side-lateral, instead fore and aft.) Anyway, any info on how you did the conversion would be great!
Thanks,
Rich

As I said, my mainsail is stock. I have now reefed the main to get the boom out of the cockpit. I guess that will affect performance, but the comfort is a good trade-off.

I put two pictures up for you. On the second picture ignore the boom and tape measure, look below it and you will see the 90 degree cam cleats I installed and LOVE! The boat same with sleeved side cables and I added pvc pipes from lowes over the turn buckles.

Hope it helps.

Great Pics, makes since now!
Thanks,
Rich

Using silicon, RTV, etc. to "seal" the deck hardware will not cut it I am afraid. It might get you by for a while but might not. The last thing we need is water getting underneath the glass shell into the wood core.

I just drilled the holes and used 5200 glue to seal everything. So anytime you cut into the deck you epoxied it with what? Then drilled into the epoxy? Sounds like a great idea.

Thanks for the tip!

The rule only applies to cored areas. Not all areas are cored, e.g., coamings iirc. But the deck/coachroof is definitely cored. Basically there are two ways to do it. If the hole is sufficiently large you can use some sort of tool to gouge out the wood between the two glass layers a bit and then fill it in with epoxy, then redrill. If the hole is not big enough to get in between to dig out the wood then you simply drill the hole a bit larger diameter than needed and then fill it in with epoxy, then drill to size. The main idea in either case is to have no wood core material exposed to water intrusion at all. All core is covered by epoxy, so even if you use 5200 or silicone and it leaks, the water cannot get to the wood regardless. You could even remove the hardware and leave the hole open and no wood core material would ever be exposed at all. Its a pita compared to simply using silicon or 5200 or whatever, but I suspect much better than having to remove delaminated core and glass later on. These boats can last forever if taken care of.
