Hello<br />I am redoing a 68 17' Cobia that needs stringers, transom, floor. It has already had a floor by a previous owner who did a bad job. I will be removing everything and replacing completely. Here is my main question. I need to do three stringers, one on the keel and two about a foot or two out from the center one. Should I remove them all and re glass in new ones or should I take out the center one, glass the replacement in and than move on to the two outer ones? I am afraid the other two stringers could be racking the boat and not removing all before I put in new wood will keep the boat twisted. How do I ensure the boat does not twist or get a hook in it while replacing the stringers? My trailer is crappy and I can't be sure that it is holding the boat straight. Lastly, should I do transom than stringers or vice versa? <br /><br />Thanks for the insight<br />John
