    I note from the report of Linda and Randy’s adventure that they were sailing with the full main and no jib in winds up to 40 knots!

    Hobie were offering a sail with the the Zip-off reefing system for the Wave but seem to have dropped the product now.

    I agree about keeping the boat flat and I aim to keep the leward hull buried no further than the midline. It’s very easy to get comfortable on the tramp and not realise that the leward hull is under water!

    I did a test today in light winds (5-9 knots) using the GPS reading from iRegatta on the iPhone. I was sitting up next to the mast most of the time but as soon as the leward hull reached the midline I moved back to the edge of the tramp and got an immediate increase in speed  – OK it was only around .1 of a knot but enough to make a difference.

    I mount my camera on the stern using a DIY “Suckastick”- as described and photograped in the Weta Yahoo Forums.

    I have an SJ3000 waterproof camera for <$100 which comes with a remote that I keep in the front pocket of the lifejacket. I usually just turn it on when I launch and run it until the battery dies – around 90 minutes.

    I think in Alistair’s situation the furling jib makes sense.

    However, the fully battened jib will always be a faster sail because it provides a better shape.

    Dangerous surf conditions to affect the entire NSW coast this weekend

    . ©

    Roads and Maritime Services has issued an alert after a Bureau of Meteorology (BoM) warning about dangerous surf conditions forecast to affect the entire NSW coast this weekend.

    A slow moving low pressure system near New Zealand is expected to create dangerous conditions from late on Friday.

    Skippers and owners of small craft should be on high alert and check the conditions before considering crossing a coastal bar or heading offshore.

    Rock fishers should also check weather forecasts before heading out to decide whether it is safe to fish near dangerous surf.

    Strong winds can also cause dangerous conditions for vessels on moorings which have been poorly maintained.

    Every skipper is responsible for the safety of their vessel and all on board. Roads and Maritime advises skippers to:
    • Check the official weather forecast before and during boating
    • Ensure the boat and its equipment is suitable for the conditions
    • Log on/off with a Marine Rescue NSW marine radio base for every trip offshore
    • Wear a lifejacket.

    If the wind forecast stays like this, I think we’d better have a short race on Sunday morning.

    Hi All

    I have now also added the location of the local sailing clubs should we wish to flashmob them to spike their interest (!) and also a couple of cafes near the water for refuelling.

    The forecast this weekend looks really windy and wet so it’s doubtful that anyone will go out on Sunday.

    Here’s hoping for better weather the following weekend.

    Mesh deflectors have been tried before but with limited success according to this thread on the Yahoo Forums.
    https://groups.yahoo.com/neo/groups/Weta-Trimarans/conversations/messages/5585

    There’s a video of some in use here but they don’t seem very effective

    The Weta is a very wet boat but hiking out from the outer edge of the tramp or sitting on the ama upwind are definitely better than lying on the tramp, as the middle of the tramp seems to get the most spray.

    If you have the additional central toe-strap between the mainsheet and harness eyes, you can then safely sit on the flat section aka behind the ama arm sailing downwind – this means your head can stay out of most of the spray from the bow.

    I find that having a smock-type spray top with seals around the waist, neck and wrists is better than using standard waterproofs as they keep you dryer which means less wind-chill – and fewer drips down the neck.

    I also prefer to sail with a stiff brimmed cap as you can use the peak to deflect some of the spray heading for your face.

    Although I always have the lifejacket as the top layer since it gives rescuers something to grab hold of. Also I put a multi-tool with a sharp blade in the front pocket of the life jacket as well as a spare soft shackle.

    I’ve modified the Maritime chart of the Pittwater area with the racing marks added which you can download from the link below.
    https://www.dropbox.com/s/uf2qozmyrh98oxq/pittwater_weta_chart_A3_V2.pdf

    There’s a smaller version here but you may find it difficult to read the detail.

    I have a KML file available with the marks as waypoints for anyone who uses a GPS or iRegatta.

    If they’re over 180lbs 20-30 mph is 17-25 knots which should be easy with the big sail if they have dinghy experience IMHO.

    If they’ve not had dinghy experience, or experience with a dinghy that requires hiking, then before they go out, show them the hiking position using the toe-straps sitting on the outer edge of the tramp as well as sitting on the ama with the harness.

    I’d also suggest you go out with them the first time and while you steer sitting on the edge of the hull (you don’t get so wet there!) while they hike out from the edge of the tramp using the toe-straps (or sitting on the ama) with the mainsheet in their hand and then swap over so they get used to both positions, before going out alone.

    Upwind, the key is to use your weight to balance the heel by hiking out first and then if the leward ama still starts to bury, ease the main and/or feather up. Conversely, on a reach (especially with the kite up) you need to bear away and ease the kite if the leward hull buries which seems counter-intuitive but it reduces the heel and pressure on the sails.

    While I can see the benefit of a zip-off reefing main in winds over 35 knots, I think you’d rarely need one if you had the small main and furling jib as you could always use the main alone and (if not already sailing) ease the shroud tension to allow the mast tip to go forward and allow you to tack more easily.

    All your videos show you lying on the tramp bracing your feet on the opposite side of the cockpit which means you’re only getting 1/4 of the righting moment you could get by getting your weight out further. Take a look at pics and videos of other Weta sailors such as this one – https://www.youtube.com/watch?feature=player_embedded&v=A46CPWFXXeY.

    I think you’d find you can get more out of your Weta than you think by learning to hike out from the outer frame of the tramp (it helps to put foam padding underneath) and when you’ve mastered this, by sitting on the Ama using the harness. Apart from anything else you get much less spray in the face!

    It would also be good if the Calendar could be embedded in the Weta Australia website.

    From my experience sailing sportsboats with gennekers, comments on the Weta forums and limited experience wih my Weta, it would seem that the rule of thumb is:
    – Go for speed by turning up in the lulls and down in the gusts. Faster and further is better than lower and slower.
    – If overpowered always head downwind – don’t luff up (you’ll likely capsize)
    – If it’s windy, hoist when heading more downwind and then point up to your course
    – Don’t cleat the gennker (you can’t anyway in the standard setup) and adjust it as you turn up and bear away to keep the top trailing edge so it’s just starting to break (harder to see if you don’t have clear sails).

    Your aim is to get to the leward mark as fast as possible but this is a trade off between distance sailed and speed which can be expressed as Velocity Made Good or VMG. While you’re not allowed to use electronic instruments in Weta Class racing (Hurumph!) there’s nothing to stop you using them in open races or in practice – and use VMG to give you an idea of what the best heading is for a given wind speed.

    You can get expensive marine instruments to do this, but a cheaper solution is to get an app called iRegatta ($9 for iPhone or Android) and a waterproof case or armband depending on your phone/tablet. iRegatta displays most of the functions of dedicated kit including VMG.
