Hi there everybody. First post and sadly its about a few problems I have. I live in Washington County Maryland so the work I'm doing is outside in cold weather, bear that in mind.

So the boat like the title says is a sorrento s23. I bought the boat last year for what I thought was a steal, guy had motor problems which I fixed the next day and took it out for a water test and it did fine, still needed some fine adjustments and a new carb but I figured on that at least anyway. I made it through the summer last year but started to see some sloppy patch and quick hide methods on the floor but chose not to really get into until the season was over and my time was open enough to really dedicate a lot of it after work and my weekends to this because I knew what I was going to find. So the floor was layered on top of the other 2 floors that were there and glassed on to them.... seems like a lot of work to half ass and not remove the older floors first. So I got the floor out and am about to start on the foam. The stringers are completely soaked and rotted into black dirt. My questions are for the bow, motor mounts, swim deck and transom, its been snowing as well so I don't have any pictures yet but I'll be posting some since you all will get a better idea and point me in the right direction.

The bow is glass and gel coat with what I'm going to call the console and passenger console being glassed to it as all one piece. How do I get under there to replace the stringers that run the full length on the boat with out removing the consoles since thats beyond my ability with what I have to work with. The glass thats already there i planned to leave one side and gut the rest then epoxy and glass the the new wood into for the stringers, not sure if that's a good plan or not please advise one way or the other.
I don't have a way to pull the motor so if the mounts are bad, they are completely wrapped in glass and not wet at all but could still be rotten inside and I cannot see it, is there anyway to save my existing ones if I have too?
The transom doesn't sound bad but if that rotten stringer was not isolated from the wood core of the transom then that is probably shot as well but I won't know more until I get to that point, what are my options with that if its a worst case scenario?
The swim deck has a crack that runs through it, and the inside is rotten, is the swim deck isolated from the transom? If it's not then I can pretty much bet on having to replace the transom.

Thanks for reading it all I know it was long, and thanks for all the advice, I know I'm going to get the typical just buy a new boat but thats not what I'm doing so please read and understand that.
 
The first question is how much time and money are you willing to put into this project? I've replaced a transom and sections of stringers. Its a big, nasty, messy, and costly job. 30 years ago I was quoted $4k just to do a transom. Depending on how much you have in it, you may be better off parting it out and buying another boat.

If you decide to tackle it, you can do the demo work outside in the winter but fiberglass needs to be done on warmer days or alternate source of heat provided for it to cure.

To answer the question about working around the consoles, I had the same problem, and I had to cut and fit stringers to fit what was already in place. Time consuming.

I'm curious to know if you and your father knew how bad the condition was, and if you did, how the price was set at $3,000. Seems high for the condition
 
SSFlook1985, I didn't remove the entire floor (S19) but a tip I learned from another member on this forum was to use a drill and look at the shavings. You should be able to tell something about the condition of that area. I had rot around the tank, one stringer near the engine, ski locker and a few other spots. I ended up taking ours to a specialist that was able to identify specific areas and replace sections. I couldn't figure out how to attached XLS file I used for budgeting. PM me if you want and we can try that way.

I have some pics (not the same boat) if you think it might be helpful.
 
Frisco B does about as good a job on that boat as can be done. Really nice work. If you go to the Hull Truth "How to" section you will get a lot of good advice and a little more encouragement. Also Classic Mako is another site with great help and information. These jobs are not for the faint of heart but if your patient and hard working and enjoy this type of work it certainly can be rewarding. GOD speed. JC
 
Thanks for the replies and other sources to find information. I used a carbide hole saw and hit the motor mounts, came out with black wood, so the motor will have to come out, i did call a few rental places locally to see about a hoist but none have one tall enough to get over the height of the stern. So that'll be something I have to think about, dad has a backhoe so that might be the route I go to pull the motor. Got into digging foam out and just about every inch is a sponge that just gushed water when I stuck it with a pry bar to get it out. I have a professional coming tomorrow afternoon to fully assess the transom so I reckon I will update again tomorrow after he comes.
 
I was already in it to go the distance, just want to know how far it is, if I need a transom so be it, just getting a professionals opinion on the transom. I spend the better half of the morning watching friscos series and writing down the materials he used and making notes.
 
SSF, Frisco made those video's quite a long time ago. Again I would check the places I've already mentioned. One more to go to (YouTube) "Sail Life" Mads is in Denmark and doing a MAJOR refit of his sail boat. He goes into some detail about the different materials he uses. Lastly go to "ONBOARD LIFESTYLE". Teal is a Master. If anybody does better than MADS or Teal there going to be pretty special. GOD speed. JC

Whatever you think the end is, triple it. Check Frisco’s dates. I believe he was in it more than a year. It can be an overwhelming project.
 
Thanks JC I'm going to watch some of the sail life videos tonight and check out ONBOARD tomorrow after work. Thanks again for all the sources, so far they have been extremely helpful with what I can expect and methods to go about it. I've caught a few of Boatworks Today's videos and they seem pretty good as well.

Golf im planning on scorched earth...
 
If your going to dig into it, good luck and keep us posted. Take lots of pictures and vids.

Haha maybe Golf, I'm sort of stuck but not stuck, is there a better method to get what seems like structural adhesive that the stringers were bedded in up? I guess when they were using it they just slopped it everywhere since there are piles all over the place and the chisel is a pain in the butt and slowwww because i don't want to damage the hull. After getting back to the transom I can say that it is encased well in glass and has no soft spots, motor mounts are shot and I figured they would be so I'm hoping to get the motor out and finish my demo and then when all the material i ordered gets here maybe rent a place for a month or something and start getting my new stringers and what not ready, that is of course after the motor comes out and the transom is 100 % good. Thanks for the advice.

Would that be better then a wide stone on a dremel?
