The first ever line of  Curtis precision molded production fins are
available for immediate delivery. The hand laminated lightweight C-13
carbon composite fin come in Tuttle,  Power, and Power Trimm boxes. These
Curtis Fins are the racers and serious sailors choice.
All sailors will notice an immediate difference with a Curtis Fin. The
board will ride smoother, go faster, point better, and not spinout. These
are the most technically advanced fins in the world, backed by Curtis
Hesselgrave's 35 years of surf fin and windsurf fin crafting experience.
The first fin, the CR-7 Course Slalom can also be used in smaller sizes
than current blades for fun sailing. In the same size pointing and control
are radically enhanced. The SR-1 Slalom also can be used on convertible,
and bump and jump
boards. It's smaller size allows great turns and great control. Suggested
retail on these fins (tuttle, powerbox, and powertrimm) is $120,  Custom
G-10 is $235.
Due out in June is the D-5 Wave in G-10 (From $89) and P-10 Polyester
(From $65). The D-5  Wave is available in custom G-10 for  $225. Available
direct or through selected dealers worldwide.

In November 1995 I bought a GFC wave-slaom fin for my Tuttle-box=20
Copello.  The fin was assembled by the local shop, Ocean Wind as per=20
GFC's instructions, using the GFC kit.

I sailed the fin two times before I went on  a 2 month=20
sailing trip down to Baja.  When sailing in Baja, I noticed pronounced=20
spin-out when sailing with that fin.  I did not have such pronounced=20
spin-out when sailing other boards or when sailing the Copello with other=
=20
fins.  When inspecting the fin, I noticed some play between the G-10 part=
=20
of the GFC fin and the adaptor.  I also noticed hairline cracks in the=20
epoxy area around my finbox.

AS my trip progressed and as i logged more sailing time, the cracks=20
became progressively worse and I had the fin professionally repaired at=20
La Ventana.  I also had the fin-box on my board repaired.  This corrected=
=20
both the spin-out and, so far, has prevented further cracks around the=20
fin-box. =20

I have written a letter to GFC detailing this incident and my local shop=20
has forwarded the letter to GFC.  However, I still await a response.  The=
=20
letter was written in March of 1996.

I suspect that your adaptors are defective.  Another GFC owner in=20
Victoria has had the same problem with his fin and remedied the problem=20
in the same manner as I, by assembling the fin with epoxy.  This has=20
ensured a rigid fin - fin adaptor assembly.

I also suspect that the defective adaptor caused the fin-box cracks.  I=20
believe that the play and looseness of the fin in the adaptor caused=20
excessive stress of the fin-box resulting in stress cracks around the=20
fin-box.

If I am wrong or my assumptions are incorrect, please let me know.  At=20
minimum, I would like some sort of response.

Obviously, this incident cost me money.  More importantly, the GFC=20
adaptor, which I believe to have been defective, caused me a lot of=20
inconveniance.  i'm sure you can understand my frustration.
    =20
Hopefully the Curtis fins you mention do not have the same adaptor as the=
=20
GFC fins.

Thank you for drawing my attention to the rec.ws posting.
As of today, this is the first I have heard from you regarding this
problem. Did you send the letter to our Canadian distributor

As for your problem with the adaptor system fit. This does happen at times
and will continue to happen occaisonally until all fins, adaptors, and
boxes are made with the precision of an automobile engine piston.
Coincidentally, we distribute Cobra and Starboard which are produced at
the same factory as your Copello. Fin box failure on boards with that
construction are rare. There is no way, however, that a poorly shimmed fin
within an adaptor would cause the box break (Actually the reverse would
tend to happen, less stress on the box, a sudden force would tend to
absorbed between the adaptor and fin). The problem was progressive over
time or a result of other forces. You did happen to notice the crack when
you had the shim problem hence your conclusion is understood.
The same adaptor system we have used for four years is now used by True
Ames, Rainbow and Chinook/Fins International. The other problem you speak
of is there. At GFC
we acknowledge that, always have.
When the adaptor and fin are not as tight as you require simply epoxy them
together as you did and your friend did. We educate our retailers to tell
this to consumers. A secondary factor is : You must shim the fin correctly
in the box as with any fin on the market, adaptor or otherwise.
In summary there is no perfect mousetrap without automotive/aviation
quality molding with
ALL components. Our industry is too small to invest at that level. In the
meantime, anyone who claims to have this problem solved is not telling the
truth. What we do have overall is an improvement over the past. This
adaptor system is the best yet. I am glad our competitors have followed
our lead and chosen the same system we have. Work within the stated
limitations by shimming or epoxying as necessary.
Thanks for your posting. I hope this clears the air for all. Any
questions, let me know.
Regards,
Bill Kline
