Lost Mold is a defined as: a process to cast a part and the mold is left in place as an reinforcement.

That being said here is what I did.

One of the stringers had a section that the wood was rotted out because the bulkhead was cut out and the stringer was not sealed up. The fiberglass cloth was solid and not pulling away from the hull. Rather than cut it out, all I did was rough up the area and apply 1708 mat over it and epoxy it. The old stringer is the mold, and the new glass the stringer. You can kick it, pound it and it is strong. Beats the heck out of cutting out and replacing.


Coosa comes from a local supplier. Here in Florida they build so many boats that there are retail/wholesalers all around. Walking into there store is like going down to the local Ace, except its all Fiberglass boat related supplies.

Hope this helps.

In between tropical storms, hurricane watches and the frickin' feels like 105 temp. I got the floor project under control.

After serious consideration of all types of materials, I decided on the following.

The tank coffin floor would be "plascore"(divincell) with a layer of 1708 on top and bottom. Weight factor is 15# versus 31# for the old floor. Plus this is the part of the floor you will never see again so no rot is good.

On the cock pit floor I am using 1/2 inch marine ply...1708 top and bottom. I stayed with wood on this part since the old floor lasted 40 years and was in decent shape. The floor grid and bulk heads where spruce. Again the old wood was in great shape. I would not of replaced it, except there where spots where water intrusion rotted the wood because of excess drilling of holes...that were not sealed.

The old gas tank was 33 years old and in excellent shape. However it was a bastard size. To low and to long. The previous owner cut the mid bulk head out to use this tank. I had Tony from Sunrise Tanks, in Venice Fl. (this guy is good and reasonable) cut down my old tank, and then make me a new tank to fit in the original coffin. The old tank is now in a forward area as a extended cruise tank. I should have approx. 80 gals of fuel. The bulk of the fuel will be in the CG point of the boat.
Most of the construction process so far has stayed pretty close to what was done originally. I thought if it lasted this long why change a good thing.

Enclosed are a bunch of pictures. I have used many of the ideas that where posted on this site, and I thank all of you for your sharing.

Getting the floors all tied together will be the next step.

I found some retro hatches...one side will be a live well and the other a cooler fish box.

Looks like it is coming along nicely, I really like the hatches, are they avaialable for purchase somewhere? Do you know the dimensions ? They look like they would fit perfect in my 27.

Thanks,

Dan

Well Planned & Clean Work Terry! You mention and show the extended fuel tank install. Did you consider or do you still have room for a fresh water hold? If you plan on doing some Island/Dive or Camping trips, it sure is a nice feature. I utilized unused space between the tank and the forward deck hold and filled it with a "bladder" type tank. I (and the ladies) sure love getting the salt spray off!

Just a thought ;)

Re: 21 Hull #136...Restoration...Progress Update.
 

Funny you should mention that...I forgot to enclose this picture. I found a 6 gallon size that would fit next to the front tank on the port size.

Watching these 21`s makes me feel like Mel Brooks behind the clacker board on the set of "Young Frankenstein". It`s ALIVE!I can`t wait to ride on one.
Are you going to round the corners of the livewell?
What kinda power have you planned?
Nice work Terry! At least you have some shade....

Sandy, Yes the livewell will be rounded. I have not started on that as of yet.

Power would be as of today :D MC 350 efi with a bravo 3.
