Agreed, looks like a graceful arc.

My FG experience is limited to glassing over a shaped foam build assembly, similar to surfboard construction. Do you anticipate any spring back or does the underside glass hold the core pretty true to the form when it's flipped for glassing the topside in this type of construction? All new to me.

BTW, nice shop floor!
 
Haven't glassed yet but my understanding is the layer of 17oz on one side should make it pretty solid.


Also the foam on the edge made it stiffer on that side of the panel.


Due to the overall size I'm building it two sections 4x10 & 6x10, no way to transport or for that matter handle it in one piece.


Trying to come up with a way to splice the two halves together on the boat, some of that planning goes to how stiff it is with 17oz on both sides.
 
Update

here's the 3/4 ply support often seen as radar arch sides


pre-wet the plywood with resin before glassing with 10ox



next pic show a wire chase I built into side to run the solar panel wires down

the under side is glassed just place temp forms in to flip and glass side two

the pink foam is a 1x2.5" glassed to edge as a reveal to make it look like thicker edge (it's only 1/2" otherwise)


THe glass cloth came out very nice and even



the top is split into two halves 4x10 and 6x10
three sides glassed now used 1.5 G MAS epoxy, no smell.

I was planning on bolting on the two arch sides place and two SS supports up front then man handling them up and attaching two halves on board.


Not happening this is to big, now going to bring it to local yard join two halves on some stands, mount the three solar panels.


Have fork lift or small crane hoist it up, not heavy, the top is about 50-60 lbs glassed, the panels are 38lbs each



it just to bulky to handle and don't want anyone hurt.
 
Interesting write up, thanks for your effort. I wish the prior owner of my boat had better integrated the shape of the hard top to the boat. BTW if you would like to save a lot of money on epoxy try Aeromarine on line. They mail order and I find the quality to be as good as the expensive name brands. It is a 2 to 1 mix which keeps things simple.
 
Greetings,
Mr. l. Very nice! One added advantage of MAS epoxy is there is no ketone blush like with West System. Good move to have the yard hoist it into place. One gust of wind at the wrong time and.....

The core is not intended to used on edge, very little strength I was told.
So his side frames are only the structural fiberglass not getting benefit from the core, plywood is the preferred materiel.

Bondo's usually have talc in them and absorb moisture:rolleyes:

here's dry fit onboard, can't believe it fit first try
I matched the slope of the front of the bridge.

The front will have two 1-1/4" SS vertical supports
Back to my shop to prime & paint now.
