RDM masts over 430
According to North Sails RDM masts are not good over 430 length, as a lightweight i have 460 skinny and love it. no issues with two different mast brands at this length(Severne and Hot sails). In fact Hot sails recommend RDM mast for their 8m GPS slalom sail. I think for non PWA sailors, even 460 has lot of benefits in RDM. I'm not sure about this claim by North Sails
From the North brochure
"Not everyone
<div data-canvas-width="283.931">knows that RDM masts make sense only up to lengths of around
<div data-canvas-width="275.0400000000001">430 cm, since they show a rather soft flex behavior as a result
<div data-canvas-width="259.11600000000004">of their smaller cross section. Therefore, they are primarily
<div data-canvas-width="280.04099999999994">suitable for Wave/Freestyle sails with the additional advantage
<div data-canvas-width="282.74199999999996">that they are easier to grip during maneuvers. On the other hand
<div data-canvas-width="283.68800000000005">large, mostly performance-oriented sails need stiffer masts with

cross section in order to ensure reaching the required stiffness"
Hot Sails Maui GPS intial impressions
I recently became a team rider with Hot and yesterday received 4 of my sails, today it was windy so I got to use one and have written about how I found it.

Aspect ratio tall vs. wide
I'm considering a particular sail and trying to decide between a 6.7 and a 7.0, the 7.0 has a significantly longer luff and actually a slightly smaller boom.
It was said that the 6.7 has the largest roach of all the sizes.
So it appears the 7.0 is a tall aspect sail.
What are the applications of a tall vs. wide aspect on a sail?
