It's a permanent repair.

West Marine has it, Bass Pro Shops, any marine store.

Answer 2

Is the cut 4 inches or 4 feet long??  If 4 inches, use marine-tex as Jtexas said and that will do the job.  However, if it is 4 ft long, fill the crack with marine-tex AND reinforce with cloth on both sides as 45 cal described.  

Answer 3

with a fiberglass repair kit. Sand a vee shape where the cut is and re-fill with fiberglass.
