Stopped by the fabricators this morning on the way to the doc and glad I did since he was about to call me so it worked out. They're TIG welding everything. He expressed a serious concern about welding up the side panels to cover the ribs. There is so much heat that is transferred during the process his primary concern was the aluminum warping even though it's .125 thick. When he welded the trolling motor mount on the front deck, I saw what he was talking about. An area about 1' away where they cut the hole for the anchor box showed a lot of bowed aluminum and the heat transfer bowed it even with a very heavy duty support brace under it. Over a 10" span it bowed out about 3/8" of an inch. He's not sweating that and they'll straighten that out. His concern was after welding the side panels into place was that the heat transfer will follow the path of the least resistance which happens to be between the ribs since there's about 18" of space between the ribs so I'd end up with side panels that would be warped. Not going to happen. The second option was to use rivets and over time those develop issues and need to be replaced and if I were painting the interior of the hull, no issues but I'm going with Linex so rivets are out. On all 3 of my G3 boats, I had rivets that held the floor in place work loose and screwing them into place isn't the best of all options out there either.
So make a long story, as much as I liked the idea of covering up the ribs it's not the best thing to do. Experience tells me that rivets would cause problems as the water on the flats kicks up now and then and the boat will take a pretty good pounding.
They'll be finishing her up tomorrow or possibly later today so the Etec will be off next week and then it's off to Linex.
Finished fab photos to come once she's home.
Bagger out
