Mcnichols bar grating load tables4/29/2024 Its great for some things, but spans are not one of them. My concern with the starboard is A) weight, B) lack of self-supporting over spans, and C) cost. Notice how I drew the bulkhead closest to you in the picture? I have cutouts to let them drain I didn't draw it in because its hidden in that perspective. the triangular side supports will also have about a 2" triangle cut out of where it meets the stringers. ![]() There will be about 3" of space under the framework. Notice how the center supports are rectangular, but the floor is angled. For now I just laid some scrap ply over floor but now I'm back to do it properly. That photo was from 2007 when I was re-doing the boat. Motor stringers were done a few years ago. Then again the word boat is actually not a word but an anagram. That is what that product is made for so if you want and you have built a nice level grid you can use it. You starboard is good for the physical floor. That is how MasterCraft is building theirs (they actually run the entire rear engine bearing stringer upper of steel in the back, since their boats deal with incredible forces from skiing/wake boarding.) If you want to get fancy and real strong on top of those use a piece of steel so you have metal to bolt your engine mounts. Marine grade stuff should last you a good long time as long as you seal it in fiberglass. Then cause delamination.Īs far as the stringers where the motor will sit you will need to go marine grade plywood. ![]() You will hold water and thus weight and future corrosion. ![]() I can't tell by your drawing but it looks like you are sealing the bottom of the hull with the stringer grid. Make sure you leave room at the bottom for water drainage. Make sure to get a resin that won't dissolve it. Won't absorb water and you can laminate it in fiberglass. You should be able to pick it up in sheets at your local hardware store, it's blue. I'm not talking about $4000 worth of carbon fiber matrix, but assuming that regular lumber would be about $150 I don't mind dropping $400 or so on a good floor that I don't have to worry about. I gotta think there is some extruded structural foam or plastic out there that would do the job. So - if I do that starboard type stuff for the framework, what can I put on it for flooring that A) won't rot, B) is stiff enough to mount things like pedestal seats, and C) doesn't weigh a ton. Since sprayed-on liners are so expensive I don't want to have to do it every time. But I plan on doing something different with the floor, maybe colored rhino liner. ![]() That would be great if I was going to carpet it when it rotted I could just pull up the carpet and replace the plywood. I can do the framework with the starboard stuff so it won't rot, but I need ideas for the flooring itself.įirst thought was plain old marine plywood. Here is the floor as it is now and I drew in an idea for supports. So, until I get enough thickness to it it will be too heavy. I know about the product "starboard" which is a marine lumber replacement, but there are two problems with it: 1) its heavy and 2) its not load-bearing. I posted on my favorite trusty baja forum and it seems like its dead over there.
