Jerry seems a little bit biased! Lol
I wonder why?!😂
Don't get me wrong, I like the Higgins boat, but I think I'm becoming more of an elco guy.
Maybe I'm the one who's biased?

To all you doubters of the Higgins superiority let me repost the key part of Andys Post here for you to remember:
"PT 613 with the slippers (flippers) and new spade type rudders (slight wedge shape), and at the same displacement, recorded the right turn in 50 seconds and the left in 49 seconds basically restoring the ELCO to it's original turning capability. For comparison with the Higgins, PT 650 recorded 36 seconds to the right and 35 seconds to the left at 2500 rpm and 117,000 lbs displacement"
So the Elco even with improvements turned 50 seconds and 49 seconds compared to Higgins 36 and 35 seconds. This is unrefutable evidence of the Higgins superior handling characteristics. I don't know about you, but if a kamikaze plane was trying to crash into my boat I would rather be on a nimble Higgins than a wallowing Elco!
Happy new year (even to you doubting Thomases!)

Yes but if the pilot had a good sense of aesthetics and and saw an Elco and a Higgins running side-by-side he'd no doubt aim for the

I found an angled main strut drawing, it is marked Void, For 1st PT 545 Only. My strut bending on my model was far from an original idea!:
I wonder if it was ever tested, and if so, how they handled installation. A forward strut drawing for PT 545 only shows no offset, maybe a universal joint on the shaft in front of the main strut? Although a prop shaft drawing for PT 545 only shows no joint.

Another PT 545 wing strut drawing (June 1944) shows no angle. The one I posted is dated March 1944. A guess would be that they actually tested angled struts at least on the wings. I didn't find an angled main center strut nor angled wing forward struts drawings.
The angled main wing struts drawing shows a single distance of 3' 6" to center line of boat compared to 4' 5" on the straight struts. So maybe both wing struts were angled in as opposed to the same direction (being used to counteract prop torque like I first thought).
