Stinger length vs rudder length

[G-UNIT]

As the title saids is it ok that the stinger with prop installed extends alittle past the rudder?
I put a sv27 stinger on a force 22 and using a speed master rudder from another boat on it and the stinger w/prop installed is about 1'' past the rudder, what affect will this have.

I think you will find it handles somewhat better now with the rudder in undisturbed water. Should improve things, IMO.

Thanks, thats what I like to hear, hav'ent got it wet yet but was just wondering if I had to change anything.

I would think that it would be the opp. Because when the prop is behind the rudder, the rudder has less leverage on the bat hull. I dont have the words right now to explain, but what boat do you know that has the rudder in front or equal to the prop?

[Heaving Earth]

I think it depends on the hull design be it v cat hydro or what have you

[G-UNIT]

It's a force 22 Deep V running a 1900 kv leo on 3-4s.
I could cut down the stinger if need be, just getting some thoughts.
I would think that if the prop was behind the rudder it would not interfear with the thrust cone of the prop.
any other thoughts ?

[G-UNIT]

Also, is the stuffing tube suppose to go all the way thru the stinger or is it cut off at the transom and another piece of stuffing tube go in the stinger, I'm asking because
their is no adjustment on the stinger, is this understandable?

On my DF pirate, my prop is just behind my rudder and it handles like it is on rails, can corner around a buoy tightly at full throttle without washing off to much speed, but the same setup on my osprey gives handling issues, i need to run wide down the straights to make it tight around the buoys. I think it comes down to hull size, shape (cat, V, deep V), positioning of the stinger and rudder on the transom and weight distribution. On the pirate the rudder is 1/2-3/4" closer to the prop than it is on my osprey and COG is slightly different, osprey runs around 25% and pirate runs 28-30% depending on conditions. I have a spare stinger fot my osprey so may try cut it down and see if it makes any difference.

Can you get a pic of the stinger, will make it easier to give advice

[G-UNIT]

I'll try and get one posted in the morning if not sooner.

[Heaving Earth]

on my v hulls the rudder is either lined up or just behind the prop. i have no experience with a rudder before the prop but most of what ive read suggests rudder behind prop is better

[TheShaughnessy]

The stuffing tube runs to the end of the stinger if its off a sv 27. No height adjustment but you should be able to get a couple degrees in either direction.

The drive dog of the prop should line up more or less with the leading edge of the rudder when viewed from the side. it is a "give and take " situation.

My Arpro and Tenshock Hydro have the rudder closer to the transom, my rigger and H&M Cat are alongside the prop, and on my Genesis the prop is closer to the transom. I guess it depends on the boat and whether you're running in circles or sporting around. But I wouldn't change anything until it's tested in water, to be sure.

I get where yor comming from, with the prop behind the rudder it will try to overpower the directional thrust from the rudder, BUT if you are runnng a oval (left turns only) with the rudder on the left side of the hull, the prop thrust wll actually help the turning as the rudder will act as a fulcrum for the boat to pivot around. There are alot factors that influence the handling and changing one thing can make alot of difference

[Rumdog]

left turn only? You mean right? In general, it is good practice to have the blade in line with the leading edge of the prop, as already stated.
