I vaguely remember a time when I could get up from the floor without grunting and holding on to furniture.  I wouldn't even attempt getting in there.

The last time I crawled up under the deck of my Vagabond was several years ago. It was harder getting out than getting under that deck.

I think I'll be able to get in there. There's no bulkhead so it's wide open.
Nat's pretty good handling the rivet gun.
Now getting back out might be a chore!
"Honey, grab my feet and pull" LoL

 

Your going to need a adolescent to crawl up in there to buck those rivets.

A lot of the Feather Crafts I have worked on had 0.050" sheeting on the front deck. 

This is all the 0.063 sheeting I have left.
I guess it would be easier to just do that much.

 

Hey Terry,
I think it would be easier to replace the whole front deck.
How thick is the sheeting?

Ray, only a centerline C channel.

AD, there’s no hope to patch it. A lot of fiberglass up there. 

Have you thought about aluminum brazing in all the pits and the crack?  Much less heat than welding (700*-750*) so zero warping and nearly as strong.  MAP gas torch and your all set.  Hobart makes good rods #770206.  You could then grind it smooth and nobody would be the wiser.  Lots of spots on my DR were done this way. The color is a bit off as the Al brazing rods are a different elemental make up to make them melt lower than the base metal so polishing would be a no go but with a brush finish nearly nobody could tell if you didn't point it out.  Give it a try and if it does not work for you you can still cut it all out.

I like the sort of V shape, you can make it a little big and trim to fit.
Is there any support structure under the deck holding it in shape?
