1977 Galaxy Apollo 720

[BrianBoat1989]

Hey everyone. I just purchased a boat and am planning on fixing it up. It is a 1977 Galaxy Apollo 120 HP. Inboard/Outdrive.

I will post pictures later.

My question at this point is, is what is the best way to redo the floor? It is rotted out badly because the prior owner decided to leave the plug in and it filled up with water.

I wasn't sure how the stringers (joists) were attached to the hull and if that is something I want to get into replacing. I would like to replace them with a plastic/composite based 2x something. Any recommendations?

The other question regarding this: I was planning on, after replacing the joists, putting a new floor down. Any recommendations on what is best for this? I have some 4'x8' sheets of 3/8" pexi glass plastic, I could lay that down and screw it to the joists. Then I was thinking of gluing 'vinal plank' flooring to that (see link below) and basically trying to route all the water towards the back where it would go into the bilge, where I was thinking of installing a bilge pump.

Thoughts on this? Any help is appreciated.

Welcome to iboats Dry Dock...

Well to start off with you don't want plexiglass for your deck (floor). The deck is a part of the structure of the boat and needs to be tied into the hull with fiberglass and resin won't adhere to the plexiglass.

As far as the stringers (joist) plywood is the best choice, but there are some composite materials out there but they are very pricey. If the wood is installed properly it'll last longer than you want to keep the boat.

Now on the routing all the water to the bilge, it should be that way now....and I would hope it had a bilge pump from the factory (although some don't). So your thinking there is perfect...you should have a bilge pump there.

Now this is very general, so when you get into it post more specific questions and all will be answered. You can also do a search on the topic as there is tons of threads on the same thing here already.

Good Luck.

Thanks for the heads up. The original floor was plywood with a fiberglass coat over it... probably be best just to keep to that and just replace it. What are your (or someones) thoughts on replacing the carpet with the vinyl?

After more investigation, I found that the stringers are actually built into the boat and are fiberglass. So they are still in great shape.

The marine vinyl is very popular and it's fine, no problems with that at all.

On the stringers....for them to be solid fiberglass would be odd, most likly they are wood covered in fiberglass. I would drill into them in a couple places to make sure it's not full of rotten wood or water soaked foam. If all is still good just seal the holes and continue with the new deck.

Good to know. Thanks.
