1989 Galaxy (TX) Bowrider Soft Floor

Hello,

I have been reading hours of old posts and thought it time describe my situation.

Boat: Galaxy (of Texas) 1790V - Bowrider
Powerplant: Sterndrive Cobra Outdrive with 2.3L Ford

I noticed the floor was soft around the ski well and knew the floor would need to be repaired, so I ripped out the carpet and after reading here and poking around started to understand how the boat is constructed. It has 2 stringers which consist of 9" tall fiberglassed plywood on edge fiberglasses to the hull running the length of the boat. Being a bow rider the boat has a cap which is riveted to the hull. The stringers make up the walls of the ski well and the stringers were carpeted (how smart). On the other side of the stringer that makes up the ski well compartment (there may be another) it is filled with foam that I am sure is damp.

I looked at the stringers and the rot is only down an inch after probing with
an ice pick. I was thinking about cutting the stringer rot down about 2-3 inches or so until I get dry unaffected wood and then splice / sister a strip of marine plywood back up to the original string height with adhesive and screws then fiberglass everything in to seal it.

Forward to the windshield and bow area there appears to be another soft area where the fiberglass cap is formed to make the bow seating area. The manufacturer appears to have laid the carpet over the plywood floor and then set the cap over everything. So there is no way to get to the floor to probe and repair unless:

1. The cap is totally removed (which looks like a royal *****)
OR
2. the area is cut from the cap (also looks like a ***** but may be better)

OPTION 1:
An acquaintance who does boat restoration said he would charge me $1300 to remove the floor and repair the stringers (sister method). I inquired how he would get to the bow area and he said that he would cut out the portion of the bow blocking the area and bond it back together. He also said that he would recover all of my rotted upholstery with new vinyl and marine plywood backing (1 color no 2-tones). He provides all materials. Should I jump on it?

OPTION 2:

I could attempt to do the job myself and buy the following:

1. 3 sheets of 1/2" marine ply wood $63/ sheet x 3 = $189
2. 2 Gallons of polyester resin $40/ gallon x 2 = $80
3. Fiberglass cloth $75
4. Adhesive $30
5. Misc mixers, paint brushes, solvents - $100
6. Ultra tuff - $150
7. Marine Vinyl - $200
8. Cushion foam - $100

Total = ~$925

Re: 1989 Galaxy (TX) Bowrider Soft Floor

you get what you pay for.. dont forget that..

The best way to do it is to pull the cap. the guys that have done it on here will tell you that its not as hard as you may think. cutting out the front is going to look bad when you go to finish it and may effect the strucural intergity of the boat..

once the cap is off pull the deck and check out the stringer.. its hard to beleive that only half is rott.. and remember rot spreads and unless you get ALL the rot it will come back quickly. also you should check the transom.

no need to spend the extra money on marine grade ply.. just use out door ply and coat is both sides and edges with resin.. if you want to do even more you can use PT but it has to be really dry!

as far as your resin extimate you are low at 4 gallons.
i am about to order 15 gallons for an 18 footer doing strings and new deck, and i might be a little low.

hope this helps

When you say coat both sides and edges with the polyester resin do you mean just painting the resin on the board with a brush?

The underneath and edges are to be coated with resin.. yes you can just roll it on so the wood soaks it up. Some people will apply a layer or two of matt on the under side for added protection. The top side of your deck should have matt and cloth. atleast 8 oz total

Re: 1989 Galaxy (TX) Bowrider Soft Floor

If you just put bare resin on the underside of the plywood, it will not prevent rot from occuring. Bare resin doesn't have any strength, and with the wood's expansion and contraction, the resin will crack, allowing moisture to enter and begin the rotting process. You'll need to put some type of cloth or mat on the underside too to prevent this.

Re: 1989 Galaxy (TX) Bowrider Soft Floor

If I decide to "peel the cap" I imagine the steps would go something like this:, Remove:

1. Windshield
2. Wiring
3. Upholstery
4. Rub Rail


I took a peek under the rub rail and the cap is attached to the hull
(and rub rail to both cap and hull) using rivets and it looks like a clear
adhesive (silicone maybe) to seal the connection.

My question is how hard is it to put the rub rail back on?
More specifically, how hard is it to get the rubber back into
the aluminum? Do you use soap or oil to get it back in?
It was pretty hard to get out .

This is of course provided I can get the cap back on straight.

You may not even have to remove the windshield. It probably is only attached to the cap. The rub rails I've had experience with were not hard to get the rubber in/out of. If yours is especially still maybe try heating up the rubber somehow to make it more pliable. To reinstall the rub rail use wood strips as a back and screw into them.

Re: 1989 Galaxy (TX) Bowrider Soft Floor

I plan on using polyester or vinyl polyester resin.

Concerning the plywood deck/floor what type and weight cloth and mat should be used on the top and bottom surfaces of the plywood deck/floor?

Also, for the stringers, what type and weight of cloth and mat should be used to glass them in?

I have read a few posts of people drilling oversize holes through the deck where screws will be used to attach the deck. Do they simply fill with polyester resin or do they use the peanut butter stuff or the PL adhesive to fill the hole?

Also, I am having trouble getting the upholstery removed form the top cap it has a screw which is inside of the foam and material I don't understand how to get a screwdriver in there to get the stainless screw out? Anyone have any tips on this?

Cut the screw, or poke around in there, move the foam back, and use a screwdriver to remove the screw.

3. Stringers

**Note: Using polyester resin

Thanks for the help.

Sorry i was out of town..

1708 is overkill for the deck but perfect for stringers and transoms.
1708 can be used to tab in the deck.

You want atleast 8 oz of the top of the deck.
This can be any combination you want but remember with poly resin you have to go matt, cloth , matt, cloth and so on..

If you plan to gel coat the deck a very thin finishing veil will give you the smoothest finish for a nice gelcoat.

92excel,

So based on your experience what weight mat and what weight cloth would you use? for the top side of the deck and underside of the deck?

I plan on using ultra tuff non skid coating with the rubber particles on the top side of the deck.

If you want to do the underside with more then just resin. then 1 oz matt will do you fine..

For the top deck i am going with 1 oz matt then 7.5 oz cloth or the 8 oz veil.
i have to see what i can get..

Cool thats what I will do.

Will post pics within the week.

I have the upholstry gutted and the carpet off.

The next step is to cut larger holes in the floor and start
gutting the foam out.

Then the cap comes off (scary).
