Safety wise. On an open boat should you throttle up when people aren't ready it gives them a place to grab before going over stern near engine.
errr shouldn't that be "safety wise only open the throttle up after warning your crew"?
Back to the frames - My boat was built & fitted out in 1984-ish. I have an A- frame. (Trawl the "wake shots" threead for a visual). Definition of functional - it is two verticals and a horizontal bit of ally tube welded together (butt welds) with a plate big enough (just) to fit a single white light to. Back then I think you could run >7knots on a single white and it was only length that forced you to have R/G.
As for getitng stuff tangled i nthe frame, the getting caught in sheets / booms etc scenario is just as likely to happen round the engine (not that I speak from experience or anthing!
), probably more so if the frame is perfectly smooth at the outer edges (i.e no cleats etc) as it will deflect the boom rather than allow the sheet to get flicked over the top a tapered pole... Every situation will be different, and the only way to really reduce that sort of nonsense at the stern is an A- frameless inboard diesel!
Dinghy racing happens by light of day - no need for nav. lights. Usually no need for GPS, as the course is usually about a mile or so in any direction, so you can see where you are and there's lots of other boats etc etc. If you got nothing to fix to it, no need for a frame!
