While the melanesia plan does not show "collision bulkheads", James Wharram actually said he "did not draw in bulkhead" as he wanted to "simplify the build".
I reckon bulkheads were both desirable AND in keeping with the Wharram design thinking.
Some reasons I considered for fitting the bulkheads are-
1. boat will not flood after collision.
2. After capsize the compartments will provide flotation
3. dry storage.
4. I gained more boatbuilding experience.
So ... today I shaped & fitted bulkheads at the bow & stern.
