400 or 430 for my weight?

Archived Under General Rigging

Question: 

shipped the 430 Goya 99 mast.  I note on the sail bag that the spec mast is 400.  Eddy (who’s great)

says the 430 should be better for me – at 185 pounds – than the 400.

I have the adjustable head extended out about as far as it can go (~13cm) and using the shortest setting on my extension (12cm).  Downhauled so that looseness in the leech is to the dot (or a shade past).  I could go another cm on the downhaul if needed but I’m trying to follow the specs.

How does this look to you –

Do you think the mast is forward enough in the sleeve?

Do you agree on Goya 430 99 RDM instead of 400?

Just getting my questions out of the way up front so I can enjoy the sail the way you intended.  Thanks.

 

Answer: 

Mega apologies for the delayed reply,,, I’ve been super swamped getting ready to leave for China (Sunday morning) and trying to get and keep all my ducks in a row….!!!

I believe Eddy did you right, and that you will be very stoked on the feel of that 430 99% mast.

At 185 pounds, you have the weight to load the mast properly and get the flex feel out of it, and also get really good low end drive and stability.

If you were 170 or under I would recommend 400 because the mast will flex a little more easily and give a lighter hand feel. The 5.4 Nexus on 430 for this weight rider will start to overpower a little more quickly than 400.

At 185, you will enjoy the low end drive, great flex feel, range and also usability in larger sail sizes.

Your rigging looks great.
Maybe a little more tension on the foot batten to clean the sail up a bit down there. Too much tension on that lowest batten will make it a little more difficult to rotate (a harder “pop”), so if you feel that, then you know you’ve gone too far.

I see you are downhauled to the dot which is perfect, then just control the power with the outhaul. +2-2.5cm of positive tension (after the downhaul is set) is a good starting point. If the sail feels too powerful or pitchy, just add outhaul in 1cm increments until it fells right. Never over-outhaul the sail because you will kill the power and make it difficult to handle in any wind condition.

The sail can be used with a bit less downhaul and outhaul in the lightest of winds to maximize the low end power.

Hope this info helps Nathan, and do keep in touch and let me know how you go!

Cheers

Can I add 303 uv protection to the sails?

Archived Under General Rigging

Question: I just bought a new 5.0 and a 4.5 banzai pro from Pascal @ xmas and i want to know if its a good idea to add some 303 uv protection to the sails ?. Will i hurt the sails by doing this. I have not used the sails yet. Probably not a good idea just wondering.
-David

Answer:

Hi David,

Thanks for your mail and inquiry. I have no experience with add on uv inhibitors, sorry.

Sails already have really pretty good uv durability,,, I mean, as long as you keep the sails out of the sun when you aren’t using them, they should last a long time.

On the other hand, Sails left rigged or left in direct or even indirect sunlight, consistently, will degrade pretty quickly,,, so unless you are OK to replace your sails yearly, I don’t recommend subjecting the sails to this level of exposure.

Hope this info helps!

Any questions, please let me know.

Kind Regards

Is my Banzai Rigged Right?

Archived Under General Rigging

Question:  I have bought me a new goya banzai 2016 5.3

Goya  mast 90% 400 2014. When I rig the sails. the sail would be on one side all the time.  I Can push it, but jumps back to the other side.

Do you have any tips?

 

Answer by Jason Diffin: Thanks for your mail and your inquiry, and stoked to see that red Banzai 5.3 rigged up on that deck/kid zone!!!

The sail looks great in the photos.

Here are a few observations-

My first thought was that it looks like the sail needs a bit more downhaul. Maybe 5-6mm more. I want to see that leech a bit looser in the the sail body between #1 and #2, and also more downhaul will de-rotate the battens just a bit from where they are and I think that foot batten looks a touch over-rotated.
If the foot batten is over-rotated then it can put a reverse (of intended foil shape) pressure on the tip f the batten and make that S bend I see in the photos.
Also, yes, it looks like the sail has a lot of outhaul on it. With the new downhaul setting, release the outhaul to neutral, put 2.5cm of positive outhaul on the sail, and that will be a good setting for nearly every condition you will experience on that sail.
My sails tend towards higher downhaul and lighter outhual(full profiles),,, profile gives power, and twist (“open/loose head”) gives range and control.
Starting from there, then I recommend adjusting for fine tuning (it’s all in the outhaul).
Have you used the sail?
How dos it feel for you?
Hope this info helps!

Save Money on Masts – Will One Work for my 4.0 and 4.5 Banzai?

Archived Under General Rigging

Question: I have 2013 Banzai 4.0 and 4.5 and would like to avoid buying 2 masts. Can I get by with just one? Would a 370 mast and 39 cm extention work for the 4.5? Would a 370 base and 400 extention be better for the 4,5? Would 400 base and 370 work for the 4.0 – and be a better total compromise than the above?

Answer:  A 370 for the 4.5 will make the sail soft and probably a bit unstable. Best choice would be a complete 370 for the 4.0, and then a 400 bottom (plus 370 top) for the 4.5. That will work very well. When mixing mast lengths, make sure that the longer section is always on the bottom.

Goya Sails Really Have Better Low End?

Archived Under General Rigging

Question: Tell me the truth about if a 4.7 Goya is almost the same than a 5.0 of another brand. I mean, not dimensions, but power or other items. Then it´s a good deal for me to get 4.7 as my biggest sail. Is new Guru as powerful as Banzai?

 Answer: I can’t speak directly about any other brand, but I can say that my sail designs have really good low end power. Also, there is a lot of people these days asking me “Is it really a 4.7?” and I say go ahead and measure it. The sails are the size they say they are. The improved low end comes form the light weight of the rig, and also the fact that we all tend to be riding higher volume boards.

4.7 as your biggest sail could work- but as long as you have enough volume under your feet, and a clear vision about what you expect from the 4.7- yes it will get you moving in light wind, but if your primary goal is planing, then maybe you need to upsize a bit. If your primary goal is to just get around and then catch and surf waves, then it’s achievable.

Rigging with Shorter than Recommended Mast?

Archived Under General Rigging

Question: What can happen if you rig a 5.0 with a 3.70 m mast or a 4.2 with a 4.0m mast?

Answer: Rigging a sail with a shorter mast (plus longer extension) will result in a softer rig overall, and rigging a sail with a longer mast will result in a stiffer rig overall.

This can work to your advantage if you want to enhance a certain handling characteristic in the sail- for example lighter sailors tend to like softer rigs and heavier sailors tend to like stiffer, more direct rigs.

Also- with the Goya mast program you can mix and match different mast length sections to achieve a certain feel (always the short section on top), and to reduce the number of masts you need to cover a sail range. For example- 4.2, 4.7, 5.3 can be covered with 4 mast parts- 400 complete, 430 bottom, 370 top.

4.2- 400 bottom, 370 top

4.7- 400 complete

5.3- 430 bottom, 400 top

Pretty nice, eh?!

Powerex OK for Goya Sails?

Archived Under General Rigging

QUESTION: I use Powerex masts either 85 or 100% carbon depending on the length. Are these suitable for use with your sails?

ANSWER: Powerex mast should be OK for the sail…
I’m very familiar with the older US produced masts, but when they moved the production to China, and then also when the company sold and production moved again, I lost touch with the finer details, quality and consistency of the mast… I can’t comment on those masts with any certainty.

Please keep Goya Masts in mind of you every are thinking of updating your masts. All goya masts are produced in the US (5 minutes from where I spent the summer in the gorge actually) and they are bar none the strongest, most consistent bend, best feeling masts I have ever used. My previous favorite was the old US produced powerex masts. I don’t mean to sound like a salesman here, but I am super fired up on these masts.

Goya RDM 400 Mast for Tushingham or North?

Archived Under General Rigging

QUESTION: Got a mail from one of our customers who wondered if a Goya RDM 400cm mast would work on sails from Thusingham or North.

ANSWER: I believe that the Goya mast with it’s progressive bend curve is very adaptable to pretty much any sail on the market, and even better, because it emphasizes low locked power and a smooth progressive twist through the head of the sail.

Also, time has proven the Goya mast to be incredibly strong.
With a team like Josh Stone, Brawzinho, Levi, Keith, Bernd all hitting every lip in sight and sometimes going down hard- and we are nearly break-free through this winter season. The only exceptions were masts broken on the rocks, or if another part of the gear failed first. I believe these USA made Goya masts are maybe the strongest masts ever…

What type of extensions do you use/recommend for the sails?

Archived Under General Rigging

Question: What type of extensions do you use/recommend for the sails? On my old Severne sails, the pulley on the foot of the sail was rotated 90 degrees, so it fitted perfectly to my extensions. Now I got a little twist in my ropes that leads to a not optimal load on the extension. My girlfriend already broke one extension because of the same problem with her Gaastra sails.

Answer: Also- point noted regarding the tack pulley. I hope to publish the threading procedure for your type of base on line soon- it can be done with no crossing. Here’s a description of the threading sequence-
From the base origination point, thread the line

  1. upwards through the sail tack pulley closest to the mast
  2. down through the base extension pulley farthest from the ground on your base, clockwise direction
  3. back up to the tack pulley and downwards through the sail tack pulley farthest from the mast
  4. back down around the base extension pulley closest to the ground, counter clockwise direction
  5. bak up and upwards through the center tack pulley
  6. down once more and finish through the base extension downhaul rope cleat
