Has anybody tested and determined why, some rudders per manufacturer are needed "wedge" profile, ( wider blade, top, slimming to botttom) over the traditional "straight" ie; speedmaster, for example?... drag is drag, easily,of course.... most wedge stlye possibly on sport hydro's and why?.... Ive a little experimental .12 rigger with a current although to scale wedge rudder( retro from another hull), that ive ideas the rudder may be issued with at least an over amount of drag, and these boats need all the help they can get...... I'm prepared to thin it down, and remove the wedge style, as my 20 boats and up all have straight profile rudders..... granted I'm not looking for a saw boat, as you often hear of actual knife blade rudders, and custom tricks to eliminate drag... I guess, question is, also looking down on all I've seen also a wedge profile to split the water........ what happens without this wedge part in any rudder?, its a pressure physics thing or what?, ala knife blade thick?.... what say does changing a wide at the top ( why?, this part of the rudder is almost always not in the water), tapering down style rudder to just a plain straight common style do?.... im sure lift encounters in here also...... basically old school boats just had a brass stock brazed to a round stock, but thin was thin.... what effects are what, as surely alot of machinists have tested this?.... lol, i need more than a 30MPH .12 boat.... thanks Mike
