another board or larger sail?

This summer I bought a kode tufskin 137 with sails severne NCX 7.5 and vandal stitch 6.5.
I have a 101 kg. I have not yet learned to jibe.
I learned to use footstraps, harness, waterstart.
When blowing between 15 - 25 knots (flat water) i control the board and everything is OK.
I am satisfied.
I want plane below 15 knots flat water
Is it better to buy another board (eg Futura 131 or 141) or larger sail?

You need a larger sail anywhere....

After depending of your wallet, change for a biger & a smaller board.

80 cm board & 9.0/7.5 ( i think 9.0 is a bit too big for the 137, 8.5 the max comfortable. )
68 cm board & 7.5/6.5.

with my 100 kilos i use a 94 cm wide board - with a 10-oh sails
this planes in 10 + knots and can be handled in winds up to 15 knots
this has increased my TOW from 12 days per season to 54 !!!
this was a bad year and i had NO other option
a fellow windsurfer and colleague uses the SB US/Ultrasonic 147 which is very similiar to my older FreeFormula
however, it is MUCH faster :-)
try it, you'll like it :-)

I agree with the previous poster.
Most of my 100+kg friends own a Formula or alike board, like the US147 to plane in light conditions, i.e. below 15 knots. Indeed all of them with a 10-oh sail or bigger.

Be carreful, this kind of board is more brekable than a Tufskin one....

You are clearly underpowered at 101 kg (I proudly carry teh same weight myself) with a 7.5 m2 sail. For me a 7 m2 sail is the largest sail I use on my smaller 106 liter board, and the wind really needs to be 20 knots or more.
When it is less I prefer to rig a 9m2 sail on a 135 liter board. Only then will you get a sufficient number of planing days. This is particularly true if you are an intermediate and not yet a specialist in effective pumping and early planing.
The difference in power between a 7.5 and a 9.0 is considerable! Thus, keep the board, get yourself a bigger sail and you will get a lot more planing days. You may also then want a bigger fin with around 46 cm of length for the lighter days.

Don't think so, PG.

The unregistered thread starter mentioned clearly that he wants to plane below 15 knots.
I really think he also needs a bigger, and espescially a wider board than a Kode to handle 10-oh sails.
He needs a lot of OFO tail width to get planing.
