WELCOME BACK
there are NOT many longboard sails on the market
I wrote a piece on it from the North American perspective
joewindsurfer.blogspot.com/2014/03/longboard-sails_4.html my most used longboard at this time is a Mistral Equipe I LCS-XR
my most used sail on it is a HotSailsMaui SpeedFreak 8.5
used to use a MauiSails TR-6 8.4 and tried a SailWorks Retro 8.0 until it cracked at the seams
the HSM SPF 8.5 does what you asked about
it is a very light sail and so can be EASILY uphauled
it is a soft sail in the sense that it can handle quite a large range of winds
have used it up to 20 knots many times
here is a small clip with the TR-6 8.4
seems I did not make any short clips using music with the HSP SPF
here's a longer one - unedited @ Cape Hatteras, North Carolina USA
ENJOY your TOW we get out when even the kites do not
as you can see in the clips, I am NOT a little homeboy, but instead a BIG beluga weighing in at about 105 kilos/230 pounds
if you are lighter, you may want to stick to the 7.x range
for me 8.x is IDEAL !!
i would even go to 9.2 for myself if i found one at a reasonable price ...
