Yes you do. Using the numbers from the above diagram, the inner trap would go:

Start
Windward mark (#1 left to port)
Leeward gate (4G)
Windward mark (#1 left to port)
Reach mark (#2 left to port)
Second Leeward (#3 left to port)
reach to finish

Trapezoids are great for multiple big fleets because you can send the first start on the outer loop and the second on the inner loop and the fleets will never see each other. Allows for safe racing for multiple large fleets. We did the inner/outer courses at Laser nationals and the reaches are definitely an area where large gains and losses can be made.

We will be practicing the reaching up here in the NE, and hopefully we can run the trap course at a regatta or two this summer.
