About a plyboat 2.1 double canoe design

[Proa42]

Hello: I'm new to the site, but an occasional visitor. I have a question for those who know. Theoretically speaking:

I have designed (using plyboat 2.1) a hull for a 27' double canoe. The WSA to Sail area is 2.5; LWL/B ratio is 12:1; Sail area to displacement is about 20+; Lateral Surface Area is around 12% of sail area; Has a narrow entry; block coefficient .64; freeboard is 11% of LOA.

Based on this data is there any reason this hull won't perform well.

Couldn't open the file for the data, but the only thing that stands out to me is that the hulls sound fat. Normally double canoes will have well less than 12-1, that is in Newick trimaran range.
