Restoration Questions and hopefully some help

[fighting irish45]

Whats up guys, as you know I am brand new to this forum and damn glad I found it.  I am trying to restore my dad's 1970's (need to find registration to figure out exact model and year) 22' CC Aquasport.  Here is my problem, the boat has been sitting in the backyard for 15yrs+.  The first issue is the crack in the top of the outer transom.  Obviously due to the core being saturated frozen then expanded than cracked skin.  My question is, should I cut the skin out from behind the transom where the crack is or listen to my friend Ken (who owns and builds Mirage boats) by cutting the deck 18-20'' forward of that inner transom and replace the core that way.  Ken says by removing the transom skin it will take away from the strength of the glass.  Since he does them all the time I want to believe him but not sure he understands the type of boat.  its seems the sides of the boat are one piece (inner side and outer side of boat)

What do you guys think???

Welcome aboard, Irish!  

I wouldn't even attempt to answer your specific question, but there will be some other members along shortly who could probably tell you.

The proper way is from the inside.  Yes, it's a ton more work.

To me its twice as much work to do one from the outside with all the fairing you have to do to the hullsides. If either way is done properly then I think the strength difference is negligible.

Welcome aboard FI  :!:  :!:
The crack you're talking about may just be the cap where it meets the transom - very common - need to see pics to know for sure.

Ok that was a nice little process, anyway I posted some cracks on the deck just to see if anyone thinks they need to be attended to.  Also I'm not sure i understand how I would make cuts on the deck and get to the transom??  Wasn't explained very well to me over the phone so I'm not on the same page.  Can anyone elaborate?

The transom pic isn't great but it is cracked on the top from port to starboard.

Welcome!

Looks like she's a late sixties 22-2 Flatback. The forward casting deck has been modified.

Depending on how much you want to spend, and since she was your dad's boat, etc...sure don't want to give you tough news, but...from the photos, looks like she's going to need at least a partial rebuild. That's where you're buddy can help.

Good news is, she's a Flatback! Extremely desirable hull.

[fighting irish45]

Its not tough news, I know and expected her to need work.  Honestly I could probably work on her for the next 2 yrs and not be completely finished.  What do you mean about "partial rebuild''?

Hey Fighting Irish,

Well for starters you have a classic Flatback! Not newer than 71`,72' was the first year of the V bottoms. What did she used to have for power? Twin 55 OMC's maybe? You have to cut the floor in front of the transom to allow enough access to cut out the wood core and cut where the stringers connect to the transom. You are going to find issues with wet foam in the stringer boxes that you are going to have to deal with, so be prepared for this to be a little more than just a transom job. All that wet foam needs to be removed and the stringers dryed out before you can think about reglassing them to the new transom.

Then once you open her up....the wet foam just keeps on going....and going...just like the bunny  

So then you're gonna want to completely rework the stringers, put in a new floor, tank, wiring, cleats, lights, mood lights, GPS map with interface, radar, side-scan, autopilot, 800 watt stereo, etc., etc.

Then you'll be an addict like the rest of us, a card-carrying member of "Aquasporters Anonymous".

And your wife will call you names...

Nice Flattie  

You might consider using the pour method to redo the transom.  Remove the top piece, take a chainsaw and slide it in between the 2 sides of the transom and chew the rotted wood out.  Keep at it until all the wood is out and then pour a synthetic transom in.  There are several examples of doing this on the site - do a search.

You may have to still do the stringers and floor but you'll be hard pressed to get a better transom than poured and the mold is the front and back glass.
