The mast on the 235 is not all that easy to raise single handed, but it can be done with the right support hardware.
There are two issues, first, the mast is VERY tall for a 22 foot boat. Second, the mast tabernackle is forward of the highest point on the cabin-top, meaning that the mast cannot be laid anywhere near flat when it is being raised.
This means that you have to have a A-Frame setup, along with a high crutch on the transom to hold it in place while you pin the base. My old setup is show below. I had helpers on the halyards because it was blowing 20+ on this launch day. With little or no wind I could do it alone. A helper always helps.
