After looking at many photos of woodies on the internet and noticing that most have varying color from plank to plank, I'm thinking about staining all of the mahogany to get an even tone, do I have to strip/bleach it first? If so, should I do that to the mahogany before I start planking the hull?

Are you sure you want to stain it all? I think that the many colors of mahogany is the sweetest about it. But it is only my opinion. You can pair the strips in stunning "patterns"

You make a good point, but while I was building my first runabout I didn't pay attention to the grain direction on each plank and they ended up kinda random. I now realize, the guy I get my mahogany from had them all carefully taped together in a bundle as they were sawn from the board, but I didn't know this and let them get all shuffled. How did you sort them?

I'll have to think about this, I really hate to strip out the natural tone only to replace it with some stain, it seems contradict the logic for using an expensive species like mahogany in the first place..

Anyway that's a sweet looking crackerbox!

I only sorted them visually, kinda paired what i thought would look good together. And in my opinion i succeeded.

I replaced the ply formers along the sides of the deck, which were too stiff, with 4x3mm pine strips, 4 of them side by side made up the right width and the slots that were already there held them in place perfectly. The resulting shape is very smooth and very stiff. I'm out of pine strips now so I need more to finish the stringers, then on to the 2mm balsa sub planking.

I'm getting ready to start planking with 2mm balsa, but I want to spray the whole thing so far to waterproof the framework, then I will sand and true up all the framing to ensure a smooth job with the sub planking, revealing bare wood for all the glueing surfaces. This got me started thinking about how to seal the inside of the balsa planking in inaccessible areas. Anyone have any tips about this? I think if the balsa isn't sealed, the back of the mahogany planking will be open to water from inside the boat. Does that make sense?

Can you brush seal it with a thin coat of thin epoxy finishing resin before planking, like Zpoxy or similar? But if it has to be sprayed you may have to resort to something like polyurethane.

I have a floor panel which is already glued in place, it ensures alignment of the formers in the cockpit area. After I plank the bottom with balsa, the area in between the two would be more or less inaccessible. Maybe I could slosh a thinned out mix of clear dope to wet all those surfaces. Would that water proof it? I don't think sloshing thinned resin around would work.

I'm not sure about the dope, I've never used it. The finishing resin I mentioned comes already thinned, not like the thick epoxy for gluing. I used it on the inside and outside of the Salty tug.

HEY Pete! Post some updated photos and/or videos to the salty thread!

Now I need to locate the german equivalent of thin finishing resin.
