Subject: Tornado Vs Modern F18 Vs Nacra f20 Carbon
Date Posted: 02 May 10 at 4:34pm

I have been sailing f18 for several years now and would like a change to
either tornado or the f20 carbon. I have never sailed against a tornado
how well does the 1970's hull design compare to the modern f18's in
terms of upwind pointing and downwind speed/depth? Is the tornado a
significant step up in speed and power compared to an f18 (i've been
sailing a capricorn)?
What do think about the f20 carbon? Besides having to take out a
mortgage to afford one! can anyone see a drawback in terms of
performance,reliability compared to the tornado, i should have
mentioned that all my racing is on handicap (schrs). Will the f20c live up
to its handicap of 0.871? and how well does the tornado compare to f18
on schrs?
All up we are about 180Kg and sail in generally light to medium winds.
any help would be greatly appreciated.

Tom,

The T is s staep up from an F18; but a manageable one.

Not sailed an F20c yet; but it will be a lot of fun. Where are you getting the SCHRS of 0.871 from?

The provisional SCHRS no. of .871 is based on the factory/design
measurements using the SCHRS formula.

Tom

The T is a great boat to sail. It can stand up to the F18 on the right course and from my experience is actually more manageable to the F18...much more gentlemanly. In my opinion one of the best value for money cats out there. (although I do have a vested interest as I have 1 for sale)

Going from conversations Ive had with those that have been lucky enough to sail the F20 they say its an awesome boat, and is totally manageable too...although as you say an expensive option

With the T now going to one design sails there will be plenty of sails available at cheap prices for club racing etc

*edit* 180kgs is slightly over optimum for both T and f20 but you will have fun on either

NacraMan

You mean the factory estimated or expected rating.

Provisional means something in SCHRS speak. Essentailly a class that is starting out may apply for a provisional rating as the first boats come off the production line (we usually measure 2 or 3). Assuming these boats are within close tolerance, the SCHRS management group will allocate a provisioinal rating while production starts to get going; once the build numbers reach the appropiate level - see http://www.schrs.com/thesystem.php - http://www.schrs.com/thesystem.php a full SCHRS rating will be calculated and I will place this on the website.

Until at least one boat has been formally measured; no schrs rating exists; A manufacturer may wish to quote an "expected" rating based on the plans; but that is all it is.

Provisional is not a term that 'belongs' exclusively to the SCHRS
organisation. Check out the definition in the dictionary and any
thesaurus.

But just to satisfy "Scooby Simon":
Based on the factory/design measurements the F20 C's SCHRS SHOULD
come in at .871

Looks like the F20 C will live up to its ESTIMATED SCHRS as in the long
distance raid(its first proper race) at Eurocat at Y.C.Carnac, France this
weekend( in 5 to 15 knots of breeze) it came 11th out of 157 starters(the
fleet was mostly F18's including the top 20+ beach cat teams in the
World)!

Tom,

My normal crew and I weigh in at just over 180 I would have thought. I know I'm just in three figures and Dan has put some weight on.

We struggle downwind against some of the lighter teams but it evens out as the breeze gets up.

I really enjoy my T, it's a lovely boat to sail.

If you want to have a test sail on a Tornado give me a shout. I am sure we can arrange it.

There are also some good bargain boats for sail at the moment in the UK.

Tom166 I sail a F20C and we are beginning to clock up the hours on our boat. I have sailed many cats for many years and I have to say that this F20C is quite exceptional. Like all Nacras it is easy to sail - very stable. the hull design lets it sit well on the water but when it becomes choppy the chine sheds the water well - getting away from the slapping effect the older 20 had.

It is fast - very fast but does not feel unmanagable in any way. I would say 165kg crew weight is probably the lowest to start out with.

All F20 C sailors I talk to are very pleased and surprised at how well the boat handles and how light it feels to sail.

I would recommend a test sail and prepare the mortgage - Its well wotrth the money for this very modern design.

I would love a go however there was one thing i missed out in my initial
post. I live in Dubai (thus the light winds) so any test sails are out of the
question.
