I feel that the van Loan rig is not discussed often even though it is a beautifully simple and practical rig. As Arne says it's a low yard angle rig which will let you increase the balance, depending on how you adjust the batten parrels. Put a drawing of a Split Rig beside the van Loan rig and play 'spot the difference'. Both rigs are a variation on the same theme and both result in simple controls and low stresses. Both will allow for maximum balance and the mast further aft than other Western junk rigs. Although the design was not approached from this end, the split rig could be thought of as a van Loan rig with camber and the sail split in way of the mast.
James, you are talking about placing the mast at 35% chord, but a word of warning might be in order. With his vast experience of the Balanced Rig on model boats, Roger Stollery reckons the limit for a safe rig is to have no more than one third of the combined sail area in front of the mast. I drew Amiina's first rig at 35%, reckoning the increased area aft in the top panel would keep the rig stable. It did, but I feel you should be aware you are playing right at the limit here and any slight deviation might start to show instability. Amiina has been sailed in some 'interesting' wind conditions, and as the rig has been reefed the ratio of area fore and aft has moved towards a more stable figure, due to the shape of the top panel. I was not overly happy when it was raced without the top panel. Looking at a new rig rig for Amiina I am wondering about setting the balance at 33% rather than 35%. It's not much difference, but we'll see.
Michael, regarding a boat the kites around at anchor, I fully agree that it's not pleasant. I have always felt that if planning to go long time cruising I would fit a double goal post as far aft as possible to 1) support the aft end of an awning/ cockpit tent, 2) support solar panels, 3) support the vane part of a wind vane system, 4) mount emergency aerials, radar, etc, and 5) make a mounting for lashed on 'blinkers' between the double uprights on each side to act as tail feathers to hopefully help stabilise the boat at anchor. I'm surprised there has not been discussion on this latter point.
Iain, Sesi's rig is based on Poppy's, and even the hull is from the same mold but with bilge keels. I believe the 'unusual' controls are simply the standard spanned combined batten parrels/ downhauls which are regularly used with the split rig. Van Loan suggests spanned downhauls and individual batten parrels, but I've combined them so that they are just slack when hoisting but only require a light tug to tension (which I often forget to do). I feel it is difficult to get a simpler set up which has all the necessary safety features.
I hope you all have a healthy and happy New Year.
Cheers, Slieve.
