Is that what's troubling you brother?
If you have followed the recent adventures of Reboot you are aware we spent some time out in some rough seas, Today I re-bedded the two fixed windows in the main salon, That provided an opportunity to see just how thick the hull is. You are looking at it. It's quite a bit of thickness and layers.
Here is a close up of the layup. The inner core (the top of the picture) is the "pretty" interior wood. Then comes a big slug of fiberglass, what appears to be another layer of wood (not sure about that) and then the gelcoat finish on the outside. Pretty impressive. Total thickness is about 1 inch.
Fair winds and following seas :)
