Default Best base & extention available?

Hi all,

I intend to change my bases and extentions (no carbon) to the system with best longterm durability and safety. Because of regularly sailing in very cold water 100% error free funktioning is essential. I tend to go with streamlined red line with us-cup and two bold system but I am not sure about two issues:

- is it compatibility with my Neilpryde X9 Wave masts which I will continue to use for a while
- is there any unintentional "autorelease" of the deckplate

Any advice and alternative suggestions are very wellcome!

Thank you,

Christian

Christian,

With a focus on an aluminum extension, you're on the right track with the Streamline Redline brand. However, you should make sure that you like the design and function of the Quick6 pulley/cleat system. While it's a well designed unit, it does thread very differently than the Chinook or NP type pulley/cleat system. If you have a chance, you might want to rig your sail with it to see whether you like it.

Regarding the universal and 2 bolt deck plate, you might want to compare the Streamline and Chinook designs. While both companies have very sound designs, the Chinook version allows you to use the universal to tighten the bolts of the baseplate. This feature allows you to easily move the baseplate to work with different sail sizes without the need for any extra tools. Now, Streamline might have incorporated something like this in their design, but I'm somewhat doubtful about that. Overall, the 2 pin cup designs of both brands should be compatible with the Streamline mast extension, but if you elect to go with the Chinook universal, it's a good idea to check just to be absolutely sure.

You should look into the Hot Sails mast extensions http://www.hotsailsmaui.com/2008/sai...ail=extensions The carbon has a bulletproof reputation and they are coming up with a revised design in carbon or composite/fiberglass or alluminum, available early June.

Thank you! Hot sails sounds intertesting but only RDM? Good to know that chinook and streamlined US-Cups are comartible! The chinook two-bold plate looks a little thicker and more plastic - even so this can be OK - just my impression by viewing the pix.

Does anyone tried to use a streamlined extension with an Neil Pryde X9 Wave? This Mast are a little tighter and I had experiences some Problems with fitting other extentions.

I just got a chinook two-bold Base (US-Cup) and streamlined extention. Everything looks very solid and is compatible (even with NP bases). By the way my new 08 tendon base features a robust security webbing (formaly known by from the rubber joint base) instead of the thin rope.

The only thing which seems a little bit strange to me, is the cleat of the quick-six fitting which allows the rope to come free (i.e. no closed channel surrounding the rope). Do I have to secure the rope e.g. by making a turn upwards (passing the gap between the rope and the extension) or can I put the overlaying rope straight down to go inside the extention?

Thanks for advice in advance!

Christian

Hi Christian,
A trick I've learned when using the Streamlined "Quick 6" downhaul set up is to take the DH line where it comes out the back of the cleat (this cleat really holds the line well if you give it a little "tug" upward around the back of the cleat to set the line in the cleat) and then run the line up over the top of the entire "Quick 6" assembly and back down beside the pulleys on the other side.
There's enough space to fairly positively "lock" the line beside the pulleys.
Then run your line into the bottom of the base and stuff it up above where the US 2 pin adapter goes into the extension.
Hard to explain in words, but if you bring the line out the back side of the cleat and up over the top of the entire cast assembly, you will find it kinda "snaps in" beside the pulleys and this adds additional security.
I took a look at the Hot Sails bases, and they come in both 30 cm (for RDM masts)and 45 cm (for std. dia. masts).
Hope this helps,

Make sure, if reliability is your goal, to use Dyneema downhaul line no matter which extension you use. It will last much longer than standard prestretched marlowe.

I've never heard of the line coming out of one of the Streamlined cleats once it's secured, but they are a little harder to use as you have to get the line into the cleat without a fairlead when it's under full tension. But, they are bombproof and well manufactured, that's for sure.

Default Extension

I have had:

Chinook Alu (overall quite good)
Chinook Carbon (broke 1)
Neilpryde X5 (bend 1)
Arrows alu (still working/ oldest)

But I have the best extension right now:

Neilpryde MXT X6 48cm
I use it on NP RSRacing and don't need a rigwinch
You get standard a dynama rope
And together with NP Powerbase it works great

I am a speedsurfer and have a lot of 40kn offshore @ sea, and the foot/base are really tight. I feel really confident, and the sails power is directly on the board

Did they fixed the "auto-release"-function of the MXT System? My concerns are that it is due to the construction including only one release button. 15 (?) years ago I had bases/extensions using the same construction produced by ART/Fanatic and (rarley) I experienced the same "auto-release". I never heared about this regarding the two-pin-US-Cup system. If you go 40 knots (never did it my self) and board and riggets separated a mile offshore it must be a thrilling swimming experience ... (think about the fact, that if you have catched your board you have to carry it back to your rig by swimming against the wind). Thats the reason why I switched to a two bold base. If the one-bold is fixed well no problem but sometimes it happens that it gets loose by time. Typically it than comes of at your first outside-jibe. No problem with two-bold base.
