Howdy!

I am looking for advice about the best choice of mast for a NP Ryde 7.0.

I have read that 430 would be better than 460, but I am not sure about RDM or SDM - it seams that 7.0 is right on the edge of where you switch from RDM to SDM. I do also have a NP Fusion 6.0, and RDM would be best for that one, but the 7.0 is my preferred sail.

Thanks in advance :)

Depends on your weight. Lighter sailors - shorter mast, rdm.

Tanks for your reply MrCranky

I am about 72 kg.

Looking at NP's mast extensions, then it seams that they doesn't make 40 cm RDM, witch I would need for a 430 mast - I guess it not a good combination then...

he he
hit the same snag as you - want to use RDM on sail with 40 cm extension
like we are used on SDM
well - there ARE 40+ cm RDM extensions - in CARBON only #$%&^*()

Do you sail your 7.0 in low, mid or high wind conditions compared to your weight? If it's the first 2 go with SDM. Is it the latter with a tendency towards high wind then pick the RDM. The RDM will give the sail a softer feel and increase the high wind capabilities. SDM masts in general give a sail a more solid powered up feel compared to RDM masts. SDM will give the sail better low wind grunt compared to RDM but can be a handfull when properly powered up.

Both with RDM and SDM pick the 430 mast with a 34 cm extension. No need for a 40+ cm extension. The Ryde 7.0 requires 464 cm of luff so the 34 cm extension will do just fine. I've had tons of NP sails over the last 6 seasons and none required a longer extension setting as advised. Must note that I only use the NP MXT extensions both RDM and SDM. Also used the UXT SDM and found that extension als requires the spec settings.

I use the sail in mid and low wind conditions, but I would like a bigger sail for low wind, maybe around 7.8.

I use a FLX35 430 SDM mast at the moment, but would like to upgrade to FLX70. I have tried a 34 cm extension with the Ryde, but it needs 1-2 cm. more downhaul, therefore I got myself an 48 cm extension and I would expect that it would be the same with a RDM mast.

Thanks for your advise, I will go for the SDM :)

Cheers,
Christian

I'm 70 kg and was in a similar situation last year. I had a 6.1 fusion and a 430 rdm mast and wanted a bigger sail. I specifically didn't want an SDM mast (new extension), so I ended up with a Severne 7.5 turbo and a 460 75% rdm mast. Some experts (and NP) think that rdm should be no longer than 430. I didn't enjoy the turbo, replaced it with a 7.5 NCX and that was my gateway drug into Severne sails (sold all my NP sails). Ridiculously stable sail, not a great bottom end, but the stronger the gusts, the faster it goes. Alas, I've decided that big sails are not for me. They give a few more knots earlier planing and that's it. And where I sail the water is rough even in 17 knots. What I have come to realize is that the lighter the wind, the more important it is to have a light mast and a stiff carbon boom. IMO, at your weight the biggest sail you can rig on 430 100% mast will be better than a bigger sail on a low carbon 460 mast.

Well worth reading
