F-32 overplaning / bow steering

Post by BeaconMarineBob » Sun Jul 01, 2018 8:35 pm

Talked with John Leed Trojan engineer on the subject of
bow steering “ over planing” on the F-32.

He stated,

1. The aft 100 gal fuel tanks play a major role in keeping the bow up on a F-32 and prevent “over planing”

2. Over planing of the F-32 was not a noted problem with the F-32.

Over loading the V birth will cause the over planing.

3. On a four tank system running the aft tank empty will cause over planing.

4. On a two tank system running her with the aft tanks almost empty will cause over planing as well as running out of fuel.😀

5. Mounting the trim taps incorrectly. Trim tabs should have no effect in the up position on a F-32.

6. Rudder size would have a very small effect on over planing.

7. Up to around 1974 Trojan used the rudders Paul Foster posted above with a bronze shank.

Trojan changed the Rudder to a smaller size because of problem with the shaft bending.

Around 1992 John Leed redesigned the pre 1974 rudder with a S/S shank.

This is rudder we sell today for a replacement rudder on a F-32.

I have had this happen to me on my 76 F32 with two full tanks. Scared the hell out of me and my family coming into NY harbor! I did manage to figure it out and always try to run bow high. I use very little trim and have not had a problem since.

When the Bow runs to low it acts like a rudder and try to steer the boat .
