That year hull there should not be any stringer worries due to they are glass only that have been foam filled. The transoms are problematic tho. Look it good, it shouldn't have any flex or cracking in the glass in the corners from flex. You can take about anything and tap up against it to tell how solid it is. Some use moisture meters and crap like this but that evolves cutting holes in the glass to stab the wood with the meter. I can look at the wood shavings if you drill a hole and tell how bad the wood looks with out buying or stabbing the meter in the holes. When you tap on it, it should sound "solid". There is a very different sound when rot is there. Solid sounds like if you were to tap up against solid glass, you wont be able to tell the difference in the cored transom section from a solid glass section if it is still solid. If it has a hollow sound like an drum or thumping sound its gone. I would tap all over the rear of the transom then compare to the sound to tapping on the side of the hull right past the curved corner on the back just forward towards the front of the boat. It will be thick glass there in the rear where the side curves into the back of the hull and should give you a more solid sound to go off of for comparison. Also if there is any screws in the transom, screw them out, if water runs out of the hole you need to run or plan on replacing it. The deck is the same way, balsa core in it may rot. You can tap that too but just walking around pressing pressure in different spots will tell you if it is bad in spots or not. If the floor presses down the wood is mush. It can be damaged but not fully rotted and still support the weight due to the thick lay ups. So if you find a few soft spots in small areas that just means that's the worse areas and you will likely find more if you open it up. Deck and transom is the main structural items to watch for but also look for blisters on the bottom of the hull from water absorption and check the gas tank for holes and pits if you can get the tank lid up. The rest is cosmetics mainly but don't be afraid of some minor stuff. It is all fixable it just depends on the price and how much you are willing to fix.
