1973 Aquasport 19-6 Rebuild

SB, with the internal wells like everyone uses now, the overflow inch and a half is either at the top of the well, or at the base of the well, but with a standpipe. Regardless, the hose then runs below deck, and out the stern.

With the oval poly tanks, we would set them up right in front of the motor(s), put the inch and a half drain centered at the rear, and hang the hose right over the transom....no T/H needed.

Only prob. ever had with salt water/hoses was with my '79 Hydrasports...factory rigged with that gray hose with the steel coiled wire in it...(looked like the hose on a vacuum cleaner).....steel rusted, popped thru the wall of the hose....boat damn near sank.

Have used that clear hose with the nylon strand reinforcing ever since. No probs there.

Rick thanks, and sorry I thought I was starting a new post looking to find a true flatback. Nice job on the boat and didn't mean to interupt. Good luck with your project.

Thank you mobygrider!

Look what came in!

So I got my new tank in. I need to let everyone know how great this company was. I spoke to Lucy from Sunshine Marine Tanks over  on the east coast of Florida. I can't speak highly enough about these people. They were quick( turn around for my tank was 1 day), the welds on this tank are the size of nickels, stainless steel electronic fuel sender, 3 baffles, etc. This tank is great! And they are priced right! I shopped many places all over the state and even in other states, they were extremely fair! Also, the the guys over at D & D Marine really helped out too. I was not able to make it to Sunshine Tanks before they closed so one of their customers "David" from D & D Marine helped me out. Good to see that there are still good people in this world, we all know they are not too many left. In a nutshell, if you need a new fuel tank, call Judy at Sunshine Marine Tanks @ 305-805-9898 and if you need Custom Rigging for your boat call David at D & D Marine @ 305-971-9527!

The last pic is my tower, just a shot of it, it is missing the upper station, not going to put that on until I get closer to the end!

Good deal, glad you're pleased....the tank is a beut, (glad u went with max capacity) the top as well. You're almost there!

Am sure the tank folks are pleased with your post....As is/has always been true, word of mouth is the best advertising...that's what good biz is all about.

Keep the pics coming!!

Here are some pics, I started the foaming process. 4lbs closed cell pour foam from US composites. This stuff is great! After poured, it expands beautifully, and when it dries it dries as hard as a rock. It will be great for floatation(heaven forbid I actually need it), but even better to set the deck on top and 5200 to the foam. the high spots can be sanded down, I played with that today. I actually ran out of the material so I am going to order more tonight. What you see is 5 gallons part A and 5 gallons part B. I will be ordering another kit with the same amount. Couldn't be more pleased so far!







Pic of the bondo putty used to fill all holes from the multiple drill holes from several rub rails. Did the same on the cap!

Thanks gran!

She sure has come a LONG way since the cluster bang on the first page. Very nice work. I am impressed
and a few here can tell you that I dont impress very easy

Thanks Bump, she has come a very long way. I couldn't be more pleased how it is coming thus far. It is thanks to everyone on this site and how helpful everyone is. Considering that I never have touched fiberglass before this project! Without our online community I would be lost!

Know this sounds simplistic, but......for the overfill on the foam, try a sharp machete. Quick and easy.

Man, you have gotten an awesome job so far.....what are you gonna floor her with?

Gran,

I went with 3/4" marine grade A ply. This stuff is ridiculously light believe it or not. Since it is kiln dried there is no moisture=no weight. I needed this thick board to bolt this BEAST of a tower to. i put a piece of 1/2" marine ply and stepped on it bare and the flex did not make me happy. I know it still needs glass, but I wanted it overdone(like everything else on this boat). So 3/4" ply for 2 reasons.
1. It didnt break the bank 5 sheets 4 x 8 cost me $325 compared to $1200 for composites which I didnt feel comfortable screwing through, even though they said you can. It was a gut thing!

Hey, you did good. And you're right, with it dry as it is....go ahead and bed, then seal her up.

Couple thoughts on  marine plywood. Lewis pointed out tonight that marine ply is not that much different than regular ply, but utilizes WATERPROOF glue in the ply. My experience with marine ply through the years is that it has more plys per comparable thickness than regular plywood......and is sometimes advertised as "mahogany marine plywood."

Guess the million dollar question is, and remains.....what do we choose to do with the UNDERSIDE of the deck? Encapsulate in epoxy? Or let it breath? Or a happy medium? Or, is there a happy medium?

Thinking through this.....we know there will always be residual moisture in the bilge. As that moisture evaporates, it rises, attaching itself initially underneath the cockpit sole. Nothing to be done about that. It's a given.

So, we can seal it up completely on the bottom, to prevent this upward intrusion....but by doing so, we prevent breathability. Water goes with gravity; screw holes, intrusions from above allow seepage: if its sealed, its sealed, rot occurs. Because its sealed from underneath.

I've made a case for both lines of thinking...... But what do YOU think? ....You young guys have done an awesome job around here lately on the rebuilds... we're about your 2 cents... chime in on your thinking on this.... ....thanks!

Gran,

My understanding from the lumber yard is that this marine grade kiln dried plywood is simply pressure treated ply then put in an oven to bake all the "wetness" out of it so you can glass to it. I simply used this because I wanted the "added protection" of PT and because the lumber yard recommended it and said "this is what all the marine guys use". The lumber yard I deal with specialized in docks, pilings, marine PT etc so they have a great knowledge of products especially for saltwater.

As far as what I plan to do to the bottom side of this stuff. I plan to use resin with 20% thinner to seal the bottom and edges very well then add a layer of 1 1/2 oz mat to give it a good seal and give a great surface for the 5200 to bond to. On the topside, I plan to do the same resin/thinner 1 1/2 oz mat and then 2-3 layers of 1708 for strength. I will decide whether or not to use a 3rd layer of 1708 once 2 layers are finished, if im happy I will stop.

Progress: All foam has been sanded down, floor fitted and sanded one last time, rigging tubes cut, tank is in, fuel lines are ran, and cap fitted. I will have more pics soon.

Let me throw in one very important aspect of Marine Plywood. No voids in the plys. If you look at other plywoods all have some voids in the layers and you wont find this in a quality marine ply. Voids are places moisture will find and the rot will start
