Seventy

Hi Francisco,

Thanks for getting back at me... so after a summer with a extreme lack of wind , hereby a picture of the guru with the suggested adjustments...sail felt good on the water... although it is quite hard to downhaul to proper loose leech.. I have extenden my Goya quiver with a Goya One 105 2015 model... For sofar i can judge ( because of lack of wind) i\'m impressed; smooth and easy on the knees on horrible choppy water... What is the recommended sailrange? ( i\'m 93 kgs). Unfortunatly i lost one of the screws of the sidefins, where could i get a new one ( and spare one)? About the boom, it has a build in suspension system...but i havent had the chance to try it out yet... really curious myself too, but because it\'s older and secondhand i don\'t want to use it on sea.. only on lakes... maybe with the autumnstorms... Thanks again for your impeccable customer support! Much appreciated..

Regards, Alwin.



Hi Alvin,

Loose leech at the top
From what I can see in your picture, you have one of the older, stiffer top/masts from another brand; this might not be the best mast for you, especially with 93kg. Having a stiffer top makes it difficult to achieve a loose leech and maximum forward drive as the looseness of the leech moves down to the middle of the sail. The bottom battens should have more shape and be closer to the mast if the bottom section is stiffer. Being this a 400 mast, it is clear that you need to start planning to do an upgrade when possible. It doesn’t need to be a new mast, but at least one that has more of a flex top bend.

The trick to make a mast like this(stiff top) work is to use minimal outhaul, just .5cm positive, and the right downhaul, not too much or too little. Having too much will make the sail gutless, and having too little will fold the sail inside out. You know that feeling when the sail breaks in the middle and the wind just flushes the sail but without the forward drive? Yes, the sail doesn’t have much range, but I prefer this over having a sail that is damped. Yes, not much range on stiff top masts.

Side fins screw.
This would be a mini Tuttle screw, right?

Range of the ONE 105 for 93 KG.

I would say that you can ride it up to 5.3 comfortably. Holland has strong currents/shorebreak ,and I ride more volume when sailing under these conditions.

On side-shore or places without strong currents/shorebreak, you could comfortably go up to 5.5 or 5.7.

I hope that I was able to answer your questions.

You might also consider not having side fins to maximize the low end of this board. Just get side covers. This reduces the drag and lets you release into a plane much quicker.

Very please with these! I was surprised by how light they were and worked really well with the smaller rigs.

The smallest masts are often disappointing in range since they are often just a ‘sawn off’ version of the larger size but these are excellent!
