Rule 3.7
Looks like another rule written to leave the scrutineer/entrant wondering just how this can be implemented ,without it being a subject for interpretation.
The reality when designing the cockpit is to make the top of the windscreen circa just below the eyeline for an average man,with any allowances for smaller crew made in the cockpit raising.A tall crew would have to bend their knees more so if a wave came over the top.You can`t keep lowering the sole or raising the screen every time.Look at Magnum Tornado with tiny Vincenzo Balestrieri and the giant Don Pruett for example.
The deck for a CUV is stressed out for circa 10 psi,with any raising of the deck to form the windscreen considered a continuation of the deck structure.
In the case of a large clear windscreen,then the scantlings are aimed at similar stress levels.
An entrant would not be expected to prove his hull was strong enough to go racing,or a scrutineer have to prove it wasn`t.One just makes sure it shipshape and `fit for purpose`.
The 5cm deflector you could argue ,could be say an angle bolted to the top of the screen c/w rubber edge moulding.It doesn`t say exactly how the lower edge is to be,so if it`s round moulding 5cm dia,so what,it`s still angled at 45 degrees and is 5cm deep.Or stick on a round edge moulding that is so big it has 5cm of 45degrees to the windscreen in it.
