I have added a couple of proa videos on Youtube.

This link shows the 18m proa in light wind sailing with new dagger board down:

It gives an indication of pointing ability compared to an older style mono. The board is 2m deep and 500mm chord. It has a thickness of 80mm and a camber of 6%. The proa tracks true when sailing around 60 degrees to true wind. Higher than this there is a little leeway and below this the board is creeping the boat to windward. The board is therefore lifted off the wind.

This one shows the proa at full power on the electric drives:

In calm conditions and clean hulls it will reach 8.5kts but it could only do that for 20 minutes. At the 2 hour rate it does 5 knots.

Dean and I continue to play with his model proa:

It is now about as developed as needs be to scale up. It is well balanced and responsive. Also gets to windward quite well. In strong winds we have had both hulls flying by increasing the sail cant but there is no independent sheet control on the model to allow the cant to be continuously adjusted when sailing.
