PDRacer performance - lug or sprit.
Ok ... lug vs sprit
We finally had two PDRacers with either rig option on the same stretch of water. The event was the Goolwa Wooden Boat Festival.
The Sprit sail design and making method is in the plan for the PDRacer (a whole $20 for 90 pages - really a course on modern boatbuilding) and the lug rig is a free option for purchasers of the plan.
Mike on the beach ... look at that sail shape. Is there enough sail Mike?
You can see a story on his boat ... the "sexy black PDRacer" below on this blog.
This was the first time the boat had been in the water.
Waiting for the start gun ... I sooo missed the start. Was really late trying to get clear wind and too far away from the line.
Mike got a very nice start and may have been in the first one or two boats to the windward mark before he had to come back and pack up. You can see the pink boat (me) trying to catch up. In this light, less than 8 knot breeze the lug was significantly faster. It does have a bit of extra area with 89 square feet to the pink boat's sprit rig at 82 square feet. Of course we will have to see what happens in a bit more wind!
And for those who wonder about the mast pressing against the sail ... the windward leg had the sail on the "disadvantageous side".
In other words, no material difference.
I took the pink PDR through the whole race ... confused my friends in the TS16 after I caught them on starboard on the last windward leg.
The PDR had the legs of the balance lug rigged 16footer furthest out when going upwind ... the guy was a very good sailor - outfoxed everyone on the first downwind leg by heading high and coming down fast on a increase on windpressure.
That was a boat of some historical significance too built as a tender to a major shipbuilding area in ... um maybe Melbourne.
Pic right is Mike coming in with his rudder in shallow mode. That buoy was attached to a long length of rope that went off to the left and was tied to the wharf.
It made sailing out of this space pretty crap and in the stronger breeze of saturday it made it exciting coming into the area too.

And now another sailing event with boats racing against each other with experienced skippers. Link below
Sprit rig won by a nose, but the lug sail was still faster. A bit more wind and the lug doesn't seem to be as fast - though it didn't really have enough downhaul tension.
