Speedster 200 Stringer Construction Exposed
I thought it may be of some help showing the bare hull of a 2004 Speedster 200, which I am repairing for this summer.
As the boat has some older hull repair, which I can not 100% trust, I decided to separate the deck from the hull and make it easy to work on the inside of the hull.
I was surprised to see some details in the inside that are really poorly executed. .
I will add more pics as the build will go on, hoping it will help others with similar problems.

The reason to lift the deck was a previous repair in the inner starboard stringer section
Then I found more damages under the starboard flotation foam
I'm thinking about cut open the inside stringer, de-foam it and check/reinforce the old patch, grind the cracks underneath the flotation foam and reglass them.
Still, I don't know if any/what material is between the outer hull and the stringer part.

Removed the PU foam wit an angle grinder/wire brush combination. The left part of the fiberglass on the bottom has some spots that are soft to the touch. When grinded, there is moisture inside.
I can not tell what material is in the void. Wood? Maybe who made the previous repair has put something under the strakes from the outside part of the hull?

Dude!! You took on a big project there...Must be nice to have all the tools to do a job like that.
I have seen a few body shops/repair shops use some wood to strengthen a repair area because of the cost of doing what your doing. Most shops or customers do not want the expense of removing 2 engines the reinforce a break that may have gone all the way thru.
Keep up the good work!!!

Tiny, I knew this will be a long-term project, but as one engine is not running, the other - who knows? The boat was parked 4-5 years. I have to check the engines completely, and so I pulled them out.
OK, I found what material is in the voids - it seems to be rot balsa. It is not salt water, so I believe the rain water came from the bow and found some passage to the stringer inside through the stress damaged fiberglass. I am enlarging a little the crack to the stern, just to see if I can get more solid material.
Then, as I will disconnect completely the ICS system, I decided to remove the ICS motor base, and at the same time prepare the now cracked parts to be laminated. After removal, I found some perforated damping material laying between the stringers PU foam and the outer hull.

That looks like a big project but on the up side, when you're done it will be just like a new boat.
GL hope you are on the water this summer.

Also started to close the removed stringer side - first with pre-cut pieces of 3 layers biax mat combination held in place with some wire, glassed and tomorrow refoaming.
While I'm there, I beefed the bow part where the u-bolt goes, laminated a base for a second bilge pump, and for a central u-bolt on the stern.
