Any one of those three items for a 44 would exceed the $30K...coine them and you are north of $100K.
I disagree. If you are willing to do all the work yourself it can be done for 30K by doing a little shopping:
1. Purchase or completely rebuild a 4 cylinder diesel: $5k-15K
2. Purchase extrusion or used mast/use the existing standing rigging: $2-15K
3. Basic fiberglass repair and paint one side with Awlgrip - $1-2K
The big issue is the labor. I suspect there could be more involved than 2 months worth of full time work.
