Fin Size for Wave kit

just thinking about getting into some wave gear for next season, as an alternative to slalom, and speed sailing...

im only going to be out on the waves when its 20 knots or more... if its over 30kntos more likely to be on speed kit on the flat water. any less bigger board on the river...

ive got a 4.7m wave sail and am looking at a wave board around 85L and maybe a 5.8m too...what do you think?

im around the 90kg mark and was wondering what size wave fin would best for the board and sail combo

85L/4.7m
85L/5.8m

4.7 23cm and maybe a 26cm for 5.8 - some crew would go smaller.

use a MFC 23cm FPT on a 84 RRD wave cult for 5.4 & 4.7 and 22cm with a 4.2 - seems to get going well and nice on a wave.

My 2 cents worth

For 90 kg Select fins the X1 wave evo 23 or 24cm use with 5.7/5.8
21cm Select fin X1 wave to use with a 5.0 you should be able to get away with the bigger fin for both sails.

If you actually want to wave sail, use a 21cm for strong days and small sail and a 23cm no bigger for lighter days 5.8, and get yourself a 5.3, trying to wavesail overpowered on a 5.8 is a pain in the #ss.

Big fins in wave boards are a waist, these boards are designed to turn, who cares if it doesn't plane in 13knots it's a wave board it's ment to be on a wave.

It's like all those people i see on freestyle boards with 29cm fins in them saying it stops spin out or something stupid like that. spin out? duh there ment to spin out..

i guess i must like small fins then. i'm mostly on a 20cm or an 8.25". only if i'm on a 5.7ish and its real light i'd go to 23cm.

It kind of depends on ur board and the conditions.

I'm thinking if you were on your 4.7 you might rather be speed sailing sine your not a small bloke. If i were you i'd run a 5.7-5.8 and a 5.2 ( or maybe even a 5.0). i'd even consider trading the 4.7 on a 5.0.

basically what PC said is the go.

Thats right Eyemhardcore. You shouldnt open your mouth at all...

well considering you like to ride tiny speed boards you should be cool with riding low volume boards

I rode a board 10L less then my dry weight in Kg this summer. was super loose but my bung leg made it much harder than it used to be. I'm now on average riding boards one size up than i used to before and finding it so much easier with minimal performance losses.

is the board the JP radical 79L or the FSW 78L.
I had the 2005 80L radical wave and loved it to bits as my big board. I cant comment on the FSW much but know the 06 is more freestyle orientated than the 08 or newer ones as indicated by the tail bevels on the 06 and 05.

If your planning on sailing lots of Down The Line stuff (margs, gero, gnaraloo) then the radical wave style will suit well. But if your mainly going to be in Perth then the real world wave style board will be more forgiving and help bring your


I get your idea about being able to sail in nuking winds, but you will quickly find that if your all set up down the beach with ur 5.8 up and it cranks in a little bit more you WILL want to just rig up a 5.3, as opposed to taking your POS VW golf home to collect your speed kit then head to the river, then rig up. Now in summer without daylight savings after work you aint got a chance in hell of this happening. you Will end up with a 5.8, 5.3, 4.7 and a 80L and a 90L wave board on top of all ur wave gear!!!

However if it really is nuking in the storm fronts a 4.2 might be more suitable. I've been blown off the water already this winter on a 4.0. but in reality sailing when its that windy isnt much fun.

edit:
5.8 will be sweet on the 79. i ran that combo alot. 20knots will prolly have you moving round the break OK i would guess.

Stringer I'm close to your weight at 88kg I use my 4.5 less than 10 times a year 4 of those days would be in summer, I use my 5.0 most winter days or Gero trips in summer and about 10 days in perth in the summer The rest of the time I use my 5.7 for about 90 % of my sailing. My main board for 95% of my sailing is about 90 litres (60cm wide) for the other 5% I use a 80 litre lots of rocker 56cm wide board. Hope this info helps.
