Correct me if I'm wrong, but:
  1. The Hobie 16 has (according to multiple sources some of which predate the push to SCHRS) 218 sqft (20.26 m2) of sail area NOT including the mast. According to the SCHRS table, it has 15.14 + 4.8 = 19.94 m2 total INCLUDING mast. That can't be right.
  2. The Hobie 18 has 240 sqft (22.30 m2) of sail area NOT including mast. SCHRS has it listed as 16+6.32 = 22.32 m2 INCLUDING mast. That can't be right.
  3. The Prindle 18.2 has 233 sqft (21.65 m2) of sail area NOT including mast. SCHRS lists it as 16.92 + 4.61 = 21.53 m2 INCLUDING mast. That can't be right.

Either all these old sources were including the mast - something I can't conceive of them doing, or SCHRS is not including the mast - contrary to it's instructions. Which one is it?

Yours in confusion,
Eric


The F18 main is 17 square meters including the mast and this is what SCHRS has for the sail area.

What is the source of your sail area number and what measurement formula was used to compute the sail area? Have you put a tape to a Hobie 16 sail and used the spreadsheet provided by SCHRS? If you have questions about SCHRS your best bet is to contact SCHRS, IMO.
