RAST vs Decklock
Hi, I'm new to the forum.
I am looking into the advantages/disadvantages of the Convetional 'harpoon' decklock system that I know is used by the RN over the Recovery Assist, Secure and Traverse (RAST) system pioneered by the Canadians.
The RAST or 'beartrap' system seems to be the best in my view at the moment by the fact that it guides the helicopter to be secured to the arresting beams and the wire tension allows the helicopter to be moved in phase with the ships pitch and gradually brought down as the wire provides a guiding and centering effect.
If this is the case why do navies still use the conventional deck lock system?
I do not much knowledge on this systems and it would be great if any of you could explain the benefits of each.
