the under tramp beam is for and aft. I added it after one of the Taipan sailors showed me how he had lifted his tramp at the back, to improve clearance by lacing to the front of the back beam.
The Mosquito's have this beam in thier rules, so I was used to having it there and attaching the swivelling cleat to it, so I thought once I had raised the tramp it would be easy to put a similar beam on Altered. Of course it also helps keep the tramp higher.
