After a few months of sitting in inside dry storage, and another unexpected boat restoration....I put her on stands yesterday, pulled the trailer bunks and have it almost completely sanded.

By my math, there is about 200sq ft of bottom to paint on a c25. Does that sound right?

Start by multiplying the length of your boat's hull (LOA) by its beam (B), and multiply again by 0.85. This formula, (LOA x B x 0.85), estimates the surface area to be painted in sq feet. To confirm the bottom paint quantity, do an internet search on "sailboat bottom paint calculator" and select the quantity based on length, number of coats and paint type like these Bottom Paint Calculator: How much bottom paint will I need to paint my boat? – Jamestown Distributors, Bottom Paint Calculator (bottompaintstore.com) and https://www.defender.com/html/bottom_paint_calc.html :)

Then back calculate the sqft based on the coverage per can as a check.
