WASZP status

Designer Andrew McDougall on the status of the WASZP…

Today we sailed the boat after installing a new production mast, a new wand control system, production injection parts, and an improved mainsheet system. As you can see from the video the boat is really coming to life now.
The sailor is Harry Mighell, (pronounced My-ell). Harry has taken the Waszp to heart and has been out testing on it more than anyone. He holds the speed record of 24.79 kn. He has been working for us for nearly 6 months now, concentrating mainly on fluid analysis. He has taken over the design of the foil tips from me and has done a magnificent job on that and getting the dynamics of the foil systems right.

You may notice that the sail is cambered (pocket luff). If you read my last blog I was fully committed to going with a bolt rope sail. We are not going that way. We have solved the issue of rigging the cambered sail by simply reducing the weight of the rig. The prototype mast we have been using was a lot heavier than the new production mast, and the new sail is also significantly lighter than the original prototype sail. It’s now much much easier to get the mast in. It’s amazing what a kilo or two will do when it’s 5 m away from you!

We did put a lot of time in on the bolt rope sail. We found two serious issues which we solved, but the solutions were not elegant and did not have a place on this clean boat.

In late November I spent a long stretch at McCongahy and resolved a range of issues.
We built fully assembled master boat to align the ‘Green Jig’ (read more here) to ensure everything lined up millimetre perfect. Everything came together really well and we built the first production hull.
We now have two hull moulds complete and another two in final preparation, along with two Green jigs, so we are ready to build hulls.
At this stage we remain on track for first WASZP’s to start shipping in March.
I just need to finalalize the sail and make sure we don’t miss our production slot.

Apologies for the shaky video, we have not had time to get someone down to do a proper shoot. So it is just me with a basic SLR, without my glasses and hanging off the rocking RIB!

  1. hearthy thanks in place here for putting it out Amac and team,

    cool pics and vid.

    would buy 1 & put a Herusail.com soft-wing-sail for windsurf on.
    put this right at deck-level and still have enough space to duck under to switch sides…more thrust plus less lateral.

    also put front-steering 50 cm. in front of the bow,

    shock dampen the hydrofoils wityh elastic cord hang-up.

    put woven 4 cm. wide nets instead of closed tramps.

    lower the weighed of the hull to 3 kg. by using Textreme
    flatten the hull to 18 cm.
    widen the back to 35 cm. flat bottom for planing / earlier takeoff.

    construct an in-sword-wand for direct control.

    the trailer / trolley could be simpler and lighter.

    the mainsheet roping is correct,
    the windsurf boom is good too.

    also put front-steering 50 cm. in front of the bow, for less rudder movements when pushed to leeward by a puff, in order to higher speed (compare Oracle 2013).

    shock dampen the hydrofoils with elastic cord hang-up, for smoother lift.

    put woven 4 cm. wide nets instead of closed tramps, for much less induced drag with only a little more parasitic drag & see the foils !! looks very cool too..

    lower the weight of the hull to 3 kg. by using Textreme
    flatten the hull to 18 cm.
    widen the back to 35 cm. with a flat bottom for early planing / earlier takeoff (test results from standstill too take-off in 4 seconds instead of 6 seconds Mach2 / KA 10 sail – windspeed 10 knots Garda 2012 see pics test hull below facebook).

    construct an in-sword-wand forsimplyfied direct control.

    the trailer / trolley could be simpler and lighter, with 3 wheels and steering the 1 back wheel… 1 connecting rod from back to front.

    the mainsheet roping is correct, finally more swinging the rudder extension backwords.
    the windsurf boom is good too, but could be 1 sided, no need for double, for saving weight.
