    best new foiler for beginner?

    This is a very tongue in cheek solution to the problem.

    We brought Mothcast out of retirement and did a re-cap of the 2019 Moth worlds.

    best new foiler for beginner?

    It depends on a few factors 1. Available budget 2. Your body weight 3. Crushing or racing? 4. Your sailing experience and what types of boat you sail 5. Expected local conditions. 6. Local fleets. 7. So you care about one design or not. Without knowing any of that, I would say try a UFO and see how you go.

    Moth Developement

    Let’s look at a comparison of two theoretical sailors with some fictional assumptions for comparison. Sailor A - 65KG - 6 knot take off Sailor B - 90kg - 9 knot take off Let’s assume three foil designs. Foil A - General foil with a top speed of 25 knots. Foil B - A high lift. Lowers the take off to 5 knots for Sailor A and 6 knots for sailor B top speed 20 knots. Foil C - Small foil. Raises take off to 9 knots for sailor A and 11 knots for sailor B. Top speed of 28 knots. Based on sailing bits prices, the foil sets are about $5000 each, so to have all three choices you need to spend $15K (the price of a waszp) Those who can only afford one set (they do exist) will choose the least worst foil option trading take off speed vs top speed. With the current 2 sets foil rules, the small sailor with multiple foils has a distinct advantage, they can use a high lift in light winds for a 6 knot takeoff and then swap to a small foil when the wind kicks in for a high top speed. Compare that with a larger sailor who can only afford one foil. The larger sailor, can try and minimise his take off disadvantage with a high lift, but he risks significantly impacting his top speed if the breeze kicks in. If the larger sailor chooses the small foil, he risks destroying his light air take off if the breeze drops. The larger sailor will probably choose the mid range foil and try and live with a lower top speed, and higher takeoff, loosing at both ends but trying to be ok in average conditions. A one foil rule, basically will force the whole fleet into a midrange foil optimised for a wide effective range, with a slightly higher takeoff and lower peak top speed. People are against the one equipment rule mainly because it reduces their personal options. The problem is that as the cost increases, less people can afford those options anyway. The most important voice in this debate is not the people at the AGM, it is the ones that love sailing Moths but can’t afford to be at the worlds to discuss the issue .

    ....got stung by the 'WASZP'?..OD foiler...

    I wouldn’t stay away from Bladeriders. The trick is getting a good X8 and then being prepared to upgrade the right bits (they need new foils as the mainfoil flap fails, and the rudder is too short) but apart from that they are a good solid club racing package. if I build another boat, I will consider using one of them as the base to avoid having to build a new hull.

    A new one, after 6 months WTF??? I keep my moths for 5 years at a minimum.

    Is it just me or is the internet filled with for sale Waszp's that have been sailed less than 20 times, or are under 6 months old ? http://www.mothmart.com/foiling-moth/waszp-2262/ http://www.mothmart.com/foiling-moth/waszp-2045/ http://www.mothmart.com/foiling-moth/red-waszp-for-sale-newport-ri/

    Not if you know what you are doing. There are some wand geometry tricks to sort out that problem.

    Phil ... I call bullshit the : RS Tera RS Quba RS Feva RS Vision RS Venture RS Vareo RS 100 RS 200 RS 300 RS 400 RS 500 RS 600 RS 700 RS 800 RS 900 RS Aero RS Elite Are all unique boats, each adding value to our sport, and they do nothing to dilute fleets. By contrast, when you have multiple manufacturers building within multi-design classes e.g. A Class or NS14, the competition for sailors business actually benefits the fleet numbers.

    F101

    Wrong, dead wrong. Wands that sense altitude near the CG of the boat are used on the Rave, Osprey, Skat, and Whisper , Laser and F101. There is no chance of pitch coupling with altitude in such an arrangement . The specs have been updated to reflect length and beam: DESIGN Long central hull gets the rudder and main foil further apart, removing some of the limitations and bad habits that other foiling boats suffer from. All carbon construction: main hull, foils, floats, beams, 2 piece mast. Very simple, well thought out control systems. All up weight: 80 kg Length 5m Beam 2.55m Sail area: 8.5m2 main + 7m2 gennaker Target crew weight range: 70-120 kg Take off wind speed: 8kts Target boat speed range: 10-25kts SO WHY THREE HULLS? Many Moths use buoyancy in the wings to help sailors get to grips with the boat, but this buoyancy is limited to helping the helm recover the boat from a capsize and does nothing to prevent the capsize in the first place. The F101 Tri configuration allows for a slender hull with enough length to prevent pitch poling, while at the same time creating a stable platform to allow novices to get out on the water with no previous foiling experience. The super slender wave-piercing outer hulls are set at an optimum angle to initiate foiling - simply sit on the windward hull, which will cant the boat to windward, then sheet in and take off! If the F101 does pitch forward, the main hull is designed to recover straight back onto the foils; the hulls additional length keeps the angle of incidence shallow. Its rocker is matched to the angle of incidence and the additional buoyancy forwards help lift the bow. The benefit applies to the outer hulls too - if the F101 falls in to windward, the windward hull lifts the boat back onto the foils. If the boat falls in to leeward there is enough buoyancy to prevent a capsize and the boat is quickly back on the foils. WHY IS THE WAND ON THE TRAILING EDGE OF THE MAIN FOIL? The F101 has its control wand fixed to the back of the trailing edge of the main foil, as opposed to the mounted at the bow which is where Moths mount the foil. There are a number of advantages to the trailing edge position, the most important of which is that the wand measures the ride height of the boat irrespective of pitch. This important factor can help to eliminate the porpoise effect which many beginners experience when learning to sail a Moth. Oh sorry Doug. You read it on the internet so it must be true. My apologies.

    So the foiling 101 is the latest in a long line of one design foilers trying to be the next laser. Some feel that they need to take to bashing the moth class as a way to sell boats. Sell your product on it's own merits and stop making up lies. For example ... the pitch control claim with a foil based wand. It makes construction easier, but it makes the boat worse from the point of view of pitch control.

    Of course there is more to it, for example, you need more rudder in waves than in dead flat water, a lot more. It's all about having range in settings.

    It would be good if you read what I posted. I know that in the UK (which is the same as GBR ), USA and Aus boats are available, but I don't think those countries can be considered as "many" places. For the majority of the sailing world, there are no Moths for sale in their country. I also checked before posting and i couldn't find any Mach 2's for sale in the UK cheaper than a new Waszp. While I know how robust the Mach 2 is, do you really think a 5-6 year old boat is as good as a new boat? I the USA, there is a 7 year old boat offered for more than a new waszp. I think you are also being rather misleading when you suggest boats like the Bladerider as an alternative. Old foilers are a total pain for all but the most dedicated. I thought the way to start in teh class was to buy an old Bladerider and I bought the best I could get. It was a big mistake and after 2 months, somebody lent me his Mach 2. Almost immediately, i knew I had made a mistake and I bought my first Mach 2 that week. While I would also agree that a "standard" Mach 2 is not really any more complex than a waszp (kicker excluded), how many are available with such a low spec? Almost every boat you can buy s/h is more complex than that, so your comment is irrelevent. As I tried to say, for many in the sailing world, the Waszp is a far better option than a Mach 2 or moth. If there is Moth sailing in your country, then you would probably go for the Moth. If you are in the UK or Oz, I think you should probably go for a Moth. If you are in the USA and reasonably near where there are moths sailing, go for the moth. For everybody else, I think the Waszp is a viable option that needs to be considered. Team_GBR, as the waszp and the Mach2 are made and sold by the same company, I can see zero difference in support coming from the company as you still get that support when getting a second hand boat shipped from its previous owner. As I see it, the big difference is that you can actually fix your moth yourself, with the waszp you don't have that option as it will no longer meet the one design rules, which insist that even the stickers need to be replaced if removed. So, don't take your sail to a sailmaker to get repaired when you rip it, gotta buy a new one. Ripped your wing tramps? New ones. Broken or bent foil, new one. Hope you are prepared to buy spares or you will have to wait for parts to be shipped internationally. If you get a moth, you can do that too, or you can pop your boat to a local boatbuilder for repairs. Phil's complexity comment is not irrelevant, you can always take the new, more complex bits off and return it to factory spec, so it is relevant.

    Looks way easier to sail than a Waszp. Removes the whole lack of static stability problem.
