I have an old 4 person canoe. It is the type with high bow and stern. (photo below)
Long story short: I want to reduce the height of the stern so I can safely car top it. It currently blocks my windscreen.
I was thinking of cutting it straight across, slightly higher then in line with the gunwales, then cutting a block of wood to fit the hole and fiberglass in place.
No rack is going to raise it the 25cm it needs to go without raising the cog too much and making the whole car unstable. The boat is v heavy and my SUV is already tall.
I don’t care about looks and I’m always on flat water.
I had a friend that bought a beautiful corvette about 30 years ago and brought it home. He took a chalk line and snapped a few lines on the roof and 15 minutes later he had the sawzall out and was cutting the roof out. He always wanted a tee top so he made one.
Snap a line and go at it. Make some decks and glass them in.
Don’t cut it. Figure a better way to carry it. You can tip the bow up so it doesn’t interfere with your vision much, it doesn’t have to sit level. Canoes are going to cover part of the windshield, that’s just the way it goes.
