I'm in the process of restoring a 1955 Penn Yan Swift and I have come to realize that I will need to replace 2 full ribs and 1 half rib. They are located near the transom (the 6th, 7th and 8th ribs). This is not something I have done before and wondered if anyone out there could give me some advise on how to go about this repair. I would appreciate any and all assistance. Thanks,

John

First put the transom back together.
Ok . I believe the ribs are white oak. You need to find the right piece of oak that has the grain uniform throughout the length you will be using. You will have to cut your piece so that the grain will be running across the the width not the thickness. You will have to make a steamer. I made one once out of a electric deep fryer and a piece of 2 inch pipe. search online and you'll find some pictures of some and hints on steaming wood. Pull one of the old fasteners out so you know what you'll need to get to replace them.I think they are 1/2 or 5/8 Bronze tacks .Cut the new rib 2 inches longer than what you need so you'll have about an inch sticking beyond the inner and outer gunwales .Assuming you have the gunwales removed you will trim the rib flush when they are back on .Once you get your peice steamed fit it into place and fasten it with the tacks . ALSO Clamp it- weight it -stand on it- hold it or what ever you have to do until it dries. After that if you want to try and make it look agged to match the others stain it before you varnish . try the stain on a scrap piece until it matches.

Thanks for your advice. I just want to clarify one point. I should remove all the fastners (tacks) from the existing ribs and when the new ribs are steamed I slide them into place and refasten? Thanks agian,

John

Yes but i would do one rib at a time so as the others will help hold the shape of the hull. Make sure you dont rush the steaming process. When its ready it will be like a wet noodle.
