Bottom line is: If you like your boat, and were not considering replacing it before the loss of the mast; then you should fix it.
If you are not comfortable with the used equipment ( a good opinion ); then bite the bullet and replace with all new. Upgrade even. Consider it a new boat that you already know well enough to understand her quirks. It may be the best of both worlds. (peace of mind is priceless)
Only you can answer the question as to how dedicated you are to this vessel.
We can only tell you what we might do; and we've never set foot on the boat.
I got an Old Fat Boat
She's Slow But Handsome
Hard In The Chine, but Soft In The Transom
I Love Her Well, And She Must Love Me
But I think It's Only For My Money
