I need a mast for a starcraft STARLETTE, The bost is 9'3".

I found some sail specs online:

Luff 10.83
Foot 7.33
Leech-AftHdBd 12.70*
Tack Ang 87.96*
Diag (clew/head) 12.86*
Head (inches) 3.50*
Area (no Roach) 39.62

Where might I get a mast or materials to build one.

Also, based on these dimensions, what height should the mast be?

TIA
