    Posted: 05 Apr 10 at 7:01pm
Having just read this thread I feel I might offer some opinion.

First as a follower of the forum I think it is correct to state self interests
before offering opinion which I have done at the bottom of the following
rambling;

The 600ff is a converted coventional boat. The 600 was and still is a great
little boat well designed and built with a loyal following. Off course
the mps and 700 have arguably moved the genre on and this creates
another reason why it works.

The moth is a highly developed development class which will continue to
move on. The latest boats from the likes of mach2 and bladerider are well
polished and finished pieces of near artwork, whilst they are expensive it
might be argued that they represent value for speed/quality. The other
options such as the Ninja offer a less expensive option but still in the 10k
region. Ultimately they will all become out developed.

There are currently two foiling options the Moth or the 600ff.

The 600ff is by no means the ideal solution it is a compromise, but it is
not a bad compromise and it is not slow. Faster than a moth on certain
points of sail ( the moth has the legs around the course )

The 600ff costs from £2500 spend £5000 and you garrantee a
competitive boat. A foil set costs £3000 plus what ever you can find a
600 for I just bought one for £500. New sail cost £700. But is not
essential just a bit quicker once foiling. ( there are a few already
converted bargains out there )

The boats wont be out developed my was bought 3 years ago and is still
as fast as any other boat including the carbon ones.

The class is not dead!

We have a new website, ok it is a facebook page but it can be accessed by
anyone via www.rs600ff.net

We have a uk circuit which consists of one event - our National
championship. It is spread over 3 weekends the first of which is fast
approaching 17th and 18th April at Weymouth and Portland.

Each event has a points weighting system with high points scoring. This
means that by the last event the points are multiplied by a factor of 10 (
yet to be decided ) so that it is still possible to get a good result from just
the last event but points mean points and the more you get on the board
the better. High points scoring means no discards required.

We have a set of class rules in the making. With a minimum all up boat
weight of 90kg the Carbon ones come out all up at 80kg so they need to
add 10kg of lead.

We are looking to the future and some of the ideas posted on this forum
have already been suggested. We have some unique ideas on the table
some of which will revolutionise how we approach our boats/classes and
sailing. All of this has yet to be discussed with the current 600ff sailors so
you will have to wait to find out.

* Perfect starter foiler to lead on to the Moth when you have learnt the
art.

* The boat is far from perfect but remember that it costs £4 - 5k for a
competitve package.

* Foiling from the wire is a really cool experience.

* It floats and you can stop and chill.

* It takes a higher crew weight over 70kg up to over 100kg see ardvark
issues comments on weight and foiling.

* The boats are robust and rarely break.

* Many used boat available to add foil package to

* RS parts and service to replace the boat parts.

* One design with a bit more freedom within the boat than the standard
RS600.

My disclaimer of self interest is that I have taken on running the class, we
have set up our own class association and I also sell the boats and parts.
All of this is being developed as we go as it has to be fitted in around
earning a living. I also have a moth at least it is a project that has been
started and may one day be finished at least I aspire to be on the water in
2010 in both classes. I feel that the 600 has given me the skills to master
the moth once I get one on the water. Why would I spend my own
precious free time doing this? Because I bought a 600 when it all started
as I saw what it offered and wanted a part of it. I Still have the boat and
the more I sail it the more I like it no one else was doing the class so I
took it on. Come and join us its a recession beater like no other.

Chris, im sure Mike would make a set of foils for you if you ever had a moth. In terms of foil you can increase the span or use a different section. Invariably there will be a bigger drag penalty but this can to some extent be balanced by the ability to push the boat harder thanks to greater leverage. The downside is that some of the current fly-boys have optimized the structure on their foils so they have little margin. Adam May once offered me a go in his boat when we were over in Bristol Rhode Island for the C-class champs in 2004 but before committing asked me how heavy I was. Being around 84kg I was approx 10kg too heavy for his foils so no go!!! Obviously time has moved on and the mainstream foils can probably take a bit more now.

Foiling has done some pretty strange things to the weight range purely based on the amount of apparent being generated - in 12 knots of wind I'm seeing 20+knot apparent upwind and at 70 kilos I'm heavily depowered on 8M square. I dont think its got anything to do with how heavy you actually are as to rather making sure you know how to get your kit to work for you...

This interests me, being on the erm larger side of 85 kilos, the moth is the one boat that i have always dreamed of sailing yet never have. Are you saying that you can get bigger foils to help earlier foiling for the larger gent? What are the rules regarding foil size? What is max sail size for a moth?

Andy your XC is the closest thing ive seen to the idea i
had in my head. The only things what would be different are
a thinner hull (i know the canoe isnt exactly a fat boy but
width isnt needed when foiling is it), a trapeze and a more
pointy bow like a very long taper to a more bullet like
shape.

Here's one I made earlier... looking a bit similar to the salty sketch.

but it's a moth / IC hybrid - with a kite and a T-foil rudder.

( converted from IC, hence XC on the sail )

it's even got the fashionable raked bow.

Not much news about sailing it to report yet though ( except that the flexible gantry for the adjustable T foil was too - err,  flexible  - to the point of failure. )

This could be the base for a development class single hander + kite, no foiling flying ).

You could call it the ....... Behemoth.

I had a bit of time on my hands so i did a rough sketch on Photoshop of what i want to build one day.

Its pretty much a 600FF but the hull is long and thin and gradually tapers to a sharpish point at the front. Its kinda like the Mach 2 design except longer and with the raked bow being more swept back and a more curved structure, similar to the floats on BOR90.

The A Class Hull thing has been done by Steve (Cogito) Clark in the USA.
