Thanks for the feedback everyone. To answer a couple of questions:
The plywood is from Boulter Plywood in Somerville MA
The sole was replaced, not refinished (see the link in the original post for more details on the process and materials used)
Here is a breakdown on cost. I already had the tools, so they are not included. I went through about half of the epoxy, sealer and poly purchased.
Sacrificial Plywood - $40 - Early on I purchased a 4 X 4 piece of Birch veneer plywood to practice on before starting. In addition to my own ability, I wanted to measure tear out and accuracy of the router by duplicating the most difficult piece.
T&H Plywood - each 1/2", 4' X 8' sheet was $200 (other sizes/prices are listed on their website). I used 1 whole sheet and about a 1/5 of the second (half sheets are available for $120 each). Not sure what we'll do with the leftover yet. I ordered extra expecting that I'd make a monumental mistake along the way and would need to re-cut some of the panels.
Epoxy (105 and 205) - $60
Sealer - $12
Polyurethane - $37
Chip brushes - $10
A rough guess on time would be ~24 hours. I kept an accurate log early on but got distracted after the dry fit. (2 for buying supplies, 4 for demo/cleaning, 4 to cut, 8 for sealer/poly coats, 2 for travel to/from/fitting to the boat, 2 for documenting, and 2 just to stare at it during different stages)
