Can a spinnaker set up fit a Prindle 19mx with the larger jib. What would happen if the pole mount would be lower to fit underneath the jib ? I am referring to the spinnaker setup for sale from Bobfraser in the classified.Ive read somewhere that i would need to go to the smaller jib to make this fit. Since i just purchased a new mx jib, i don't want to change . Also, what is the life span of a spinnaker ? Fabric looks to be very delicate. Do they need to be changed often ? -

Not familiar with an MX, however I will comment on the spin life span.
The spin is a light weight material and is relatively easy to tear if exposed to sharp points. Your spin system would be set-up to avoid that though.
A Spin will normally only hold its factory shape up to one season under normal racing use. The top level guys get one or two new ones each season. However plenty of people race them 2-3 or even 4 years. People use them for day sailing much longer than that, however the spin will be far from a competitive shape by then. One of the guys we sail with has one that is original to a 2005 Nacra F18. If you were to fit an F18 class spin, you should should be able to change it out every few seasons with a retired one from a racer pretty cheaply.

I am pretty sure - my friend owns/sails the original p19MX boat and it came with a gigana-mongous spin (symmetrical i think)

I ran a spinnaker on my P19mx and successfully used both the original jib and also the mx jib. The original 19 jib worked very nice ... especially after I put a furler on it !

Fabricated a spi setup on my P 18-2, can't see any problems
to do the same on a P 19MX.
The spi-pole runs under the bridle, shouldn't be a problem with
a jib at all.
The life-span of a spi really depends on how you use it,
like bacho said, its easy to tear. So tape every shackle and sharp
object with vulcanising tape, set it and pull it in at a downwind angle.
I am now using my third spi in almost 5 years.
The first one got tangled round a shackle whilst hoisting , the fabric
is so light I never noticed I was shredding it.
The second blew in a big gust.
Overhere in the Netherlands, there is a big community of F18 sailors,
so its relatively easy to get hold of a second-hand spi.
Some points of attention,
the forward bridle to the spi-pole tack position. They attach to
the tips of the bows, reinforce the bow-tips by drilling a small hole
in it and eject some epoxy paste in the bow-tips for a more rigid
construction, learned this lesson the hard way.
The pull on the forward bridle, using a spi is quite force-full.
Assuming you want to attach the sheet-blocks for the spi to the
tangs of the back-stay, don't "fix" you're set-up straight away,
leave some slack in the front bridle so you can raise and lower
the spi-pole tip.
make it possible for the tack-block to move for and aft.
look for the best sheeting-angle by raising and lowering the pole
and moving the tack-block . Once found, fix it permanently .
Hope this helps, André

Great info ...and excellent tips, Andre . Ejecting epoxy into bow-tips ..makes a lot of sense. Wouldn't want to damage boat with these modifications . -

I spoke with my friend who owns the "original" (prototype) MX19
Boat came with a full size jib and a slightly smaller one to use with the spin - both jibs had full battens
He ended up putting a furler on it as well so he now has 3 jib.
I personally only fly my spin and jib out in VERY light air. In heavy air, 3 sails is too much for me to manage -

You have a good point . I do not go out in winds under 8-9 knots ..(been stuck in middle of lake a few times with no wind ). Is a spinnaker really required when wind is good ? I do not race it...just fur fun. -

Had a 19MX for 5 years, and boat was already set up with spin & pole. The barber hauler tracks were removed; that runs down the hull/tramp area. Ran this setup with blade size jib only, w/self tacker setup on the front beam. Had a larger MX jib, but never used it b/c did not have the needed barber hauler setup on the boat. The only potential problem I see would be the lines of the spin sheet and the barber hauler setup having a possible over lap and difficulty with sheeting the spin depending on position on the boat that sheeting is being down @. Could work if the spin block mounted to the forward beam is position correctly. Putting a-lot extra sail out(from larger MX jib) when spin is up......Good luck!!

If I had a P19MX or a 6.0NA, I personally would probably not bother with the expense of a spin. Those big jibs really have some power downwind compared to the smaller blade jibs. A spin may give you less gain than your expecting.

nothing is required...
spins add an entire new dimension to sailing.. the ability to either point deeper than without a spin
or heat it up and fly a hull downwind.... you can can/should move faster downwind and improve VMG
with this new "dimension" comes the expense of the gear (sails, poles, snuffer rings/socks, lines, blocks, etc) and more items to maintain and even with maintenance, stuff will break.
(IMHO)if your not racing or competing against other MX19's, i wouldn't worry about it at all until you get bored with (or master) your current setup. save the money and purchase a brand new main/jib if you want to turbo charge your boat
that being said, i had mine out 2x times today, and love it and don't like to sail with out it, even if i don't end up using it

Should be, INJECT some epoxy paste. Sorry, sometimes the language
barrier is breaking me up.

no problem , Andre .
Your english is very good , I understood the first time . That's a nice setup you have on the 18-2 .Do you use the spinnaker a lot ? -

Thank you, the picture shows the spi-setup version 1,
with a cheap secondhand spi. The pole is way to high up and
I didn't use forward bridle then. Could only sail very deep with
this setup.
When I lowered the pole to point a bit higher in light conditions,
the tip of the pole started to bend to lee, that's when I made
the forward bridle using dynema rope instead of steel wire.
Copied it from Tornado setups at the club.
With a newer spi, the pole-tip down, little more confidence,
I started using the spi in more moderate wind conditions.
Thats when the bow tip cracked under the load of the forward
bridle, and I did fix it the way described.
I always take the spi on the cat when we go out, and use it when
we dare. Thats up to 5 beaufort.
Solo, the spi is a handful, so I only use it in light wind-conditions,
I just cleat the jib sheet and leave it as is. Mainsheet and tiller in
one hand, spi sheet in the other. And party ! Managed to hike out
twice in this configuration, but found it quite scary to be honest.
So, its a learning-curve which I have to do all over again, cause
I sold my P 18-2 last fall to get some recourses for my Tornado
project.

Can anyone comment on the additional force/stress that a spin will put on standard P19 (or for that matter a an MX)?
