View Full Version : z fins differences

21st June 2012, 09:44 AM
Hi to all.

Things are becoming more and more confusing in term of fins.

Does anyone knows what differences are between ZF and ZE fins...?

Does it worth buying a second hand ZE fin in terms of performance and durability..? or should i go to a new virus fin.

Also what is the low wind limit of the 68 with an 11.0 and 75kg rider.

Some light riders are using it quite successfully even in 10 knots.

The ZF is his latest model which started appearing earlier in the year, the ZE is the original model which has been around a few seasons now. The ZF is a fairly different outline, and I believe a different construction method. Arguably you would say any 'newer' model is better than the older model?

I haven't really sailed either to tell you what's best, but I see TONS of both Z models on the tour these days, which suggest they are more popular than Virus or other fins. At the front end of the fleet there is more guys on ZF fins (ZF 71 S- on 167w and ZF 70 S- on 167normal).

Low wind limit will probably depend on what board you are on. I would think at your weight on a 167w you could get going in anything above 8 knots with a 68 and 11.0m. The wide board does not need much power from the fin or a big sail to get moving... I only use 11.5m as my lightwind sail and I'm 85kg.

Thanks Sean for the answer.

What I understand is that there is no need for large cutdown fins nowadays because new fins give a lot of power.
So 70-71 ones propably work as light to medium winds
And 68-69 fins work in medium-high winds
Please correct me if i am wrong,as I am just doing assumptions.

I am basicly looking for a 14-25 knot fin for my vapor board
but I don't want to get stuck with a fin that work in 20knots and above as the old days 68 fins.

On the new Starboards, you are correct, not very many people are using bigger fins than 70-71 ... I am using one 70cm VMG in all conditions from 6-35 knots!

That being said, the Vapor is slightly different. Do you have the new Vapor 2, or the original Vapor? I had the original Vapor for a few seasons (great board) and was using a 75cm cutdown in light/medium winds and a 70cm in stronger winds. I'm not 100% sure about the new Vapor though (maybe ask Ross/Arnon on the Gaastra forum?) as it has a much wider tail. That being said, you are a lighter rider, so maybe a 70cm is fine for nearly all conditions on this board as with an 11m you probably don't need to go such a big fin ...

Let me know about the board and can try to help more :-)

Sean, I ve got the original vapor.
and i am riding with 11sail until 18 knots and 10sail above 18knots
If you have any suggestion that would be nice.

I got a feeling the new ZF will not be powerful enough for the original Vapor board .

If you plan NO plan to change to the SB167 , the ZE 0S- is an excellent fin.
BTW I'm 70 Kg 11m on HWR. I like my ZE0S- very much.

Haven't tried the newer Z fins but I know Ross and Arnon were using ZE 70's in the original Vapor in most wind conditions. Also Ross was using a Kashy 70 XS (as well as Steve Allen back when he was on Gaastra).

I think you'll find a 70 of anything relatively new - ie, Z-Fin, VMG Blades, Virus, Boss, Kashy etc etc will do quite well for nearly all conditions ... if you want a touch more power in really light winds (<10 knots) a 72cm cutdown would help. I don't think at your weight you will need anything bigger ... the original Vapor is quite a free sailing board, it rails very easily and gets a lot of lift from the fin with the outline, so you don't need to put massive cutdown fins in it! Make sure you keep the mast-track around the middle in this board - i see lot's of guys using it further back than middle, but I think that stalls the board as it already lifts the nose enough just from the aggressive rocker it has!

Thanks all for the answers.
I 'll go with the 70.
