Adding hard points for hardware
At this stage I have started to think about how to attach hardware to the boat. There are several areas that I think probably need to be hardened or reinforced for bolts and screws. The main areas of concern are:

Through points for the front springboard.
Front sheet block attach point
Seatbelt attach points
Mast helper attach point
Mast base attach point
Rear sheet bock attach point
Rear sheave attach point
Rear plank attach points

Any others?

If there are any structural engineers or experienced boat or aircraft builders out there that think I'm over or under doing these reinforcements please send me an email and let me know. I don't want the thing to crack up the first time I take it out and at the same time don't want a heavy. boat. It would be nice to get a second opinion on these reinforcements before I enclose it with the final skin of s-glass

I found there are a few ways of doing hard points. If you know of a better way or think these won't hold up send me an email. I didn't want to have any wood that could rot on the boat so I'm using fiberglass fill and epoxy to create the attach points.



This hard point is on the inside of the cockpit at the front behind the tunnel where the springboard slides in. There will be two bolts that pass through the front springboard, through this block of fiberglass and bolt to the bottom. There is also a hard point in front of this tunnel, outside of the cockpit where the springboard passes through the front.



This hard point is the rear attach point for the front springboard. Bolts also pass directly through and bolt to the bottom with nuts and washers.



Bottom View- This is the front where you can see the hard points. The void is where I need to add chopped mat fiberglass and epoxy to create the hard point for the front springboard attach point.

The horizontal band of fiberglass in the middle of the photo is the inside front springboard attach point and a support that runs perpendicular to the length. It's 12 layers of glass recessed into the foam. I thought this was necessary to help carry the load of the front springboard to the outside beams that run the length of the hull.



Bottom view- Front springboard rear attach point. It also has twelve layers of s-glass recessed into the foam. Like the front attach point it will hopefully help distribute the load from the front springboard across the bottom and to the sides of the hull. Eventually it will all be embedded in the final layers of glass for the skin.



There is a 10 inch reinforcement in the rear made up of 6 layers of s-glass directly below the mast base to help distribute the bending loads from the shrouds and sail down force.




The voids have been filled with glass mat and epoxy and sanded smooth.
