A friend and I have been debating canoes for lake camping in New York's Adirondack Lakes.

He asked me to consider the Placid Boatworks "Spitfire" at 12' long and their "Rapidfire" at 15'

Placid's marketing describes the Spitfire as a very fast boat and they emphecize their CF&Kevlar vacuum infused technology yields a Spitfire of 20-24 lbs (depending on kit.) I am bigger than my friend and would require the 15' Rapidfire at 28 lbs. Placid does not offer plans.

Nick Shade's "12' Nymph" seems to be similar to the Spitfire.

Am I interpreting the numbers correctly?

An interesting thing about Shade's design plans is that he places a building form every 12". If this is true for the 12' Nymph, then it seems I could get a reasonable replacement for the "Rapidfire" by moving the forms out to a 15" spacing.

Does anyone have any experience with the Placid boats or the Nymph? I hope Nick could weigh in with his design intent for the Nymph and whether the boat would be managable if built as a "Stretch Nymph."
