The base and the mast itself look very similar to the mast that was on my NT 37 Pilitak (2002). However, my boom was definitely different, and there were 2 winches (single speed “sailboat” type) mounted on the assembly to enable the lifting of “heavier” objects like a small dinghy. The given dimensions sound like what my mast was. I temporarily took the mast off while fibreglassing in the pilothouse wall to deck joint. The mast removal and reinstallation was fairly easy. Hope this helps a bit.
