A mast did come with the boat, an Isomat. Isomat went out of business several years ago but parts are still available through Rigrite and Charleston spar.
The mast kept me awake at night as there were quite a few thing about it that concerned me.
The biggest concern was that the gooseneck attachment was 22 inches above the base of the mast. This meant that when working on the sail the boom would be somewhere around my knees. Not good.
The gooseneck could be moved but that would mean major surgery as the entrance gate to the slot would have to be moved as well..... a bit of a Frankenstein arrangement in my mind.
There were a lot of gouges in the mast - this would mean painting at the very least.
The spreaders were missing. New spreaders would be in the region of $600
The boom was an angular ugly thing.
I decided on a few exploratory Craigslist listings and also posted it on the Westsail owners board.
It was sold in short order to my amazement....for 75% of the cost of a brand new LeFiell which is what most of the Westsails use.
