Hospital Hop...how to stop it?

[AndyKunz]

Been tried, too, in the way back (10-15 years ago). I ran a boat with in at the 2000 FE Nats - water slams removed by canard after 1 lap.

Capt..

The buoys we use are made by Kershaw floatation in FL.

They are 12” foam spheres that one cuts in half. The great thing about these buoys is that they are firm but not hard. They lay flat on the water.. The boat does more glancing then hitting.. you have to hit them dead straight on to damage anything and truth is I have only ever broke a outrigger on one of these as they have a tendency to launch the boat…not grab it.. Any of this make since?

I have never seen this type of buoy at a FE race and I have always wondered why? Anybody help.. Maybe I am missing something?

Anywho…

ROCK ON

O yea.. one more thing.. the club paints the buoys.. the reason this is done as when struck it leaves a paint witness on the boat.. great info if needed for the CD.. Just make sure you clean it off before the next race..

Those sound pretty cool! But I don't think my tug could drag them out and set them without them flipping over on the way. I may try a smaller one to test. We are not allowed to use row boats or swim (even if you wanted to) in the park ponds...so we use a RC tug. See this thread for tug pics.

Not sure, but I've heard that rounding the bottom front of the rudder will produce some lift?

Mike,

That's so the bottom of the rudder doesn't become a planing surface, right??


I should have noted above... I almost ALWAYS start out with my struts... all of my struts (monos and Hydros) flat... then tune from there... Otherwise, you can end up fighting a self-induced problem... Plus, it puts all of the thrust pointing in the direction it needs to be pointed!!

oho.. nope-a-roni....

Now adding a radii to the lower leading edge..

[sailr]

Not sure I follow. See the attached drawing. Maybe I'm missing something here!

Sailr,

If you read post 21 it stated round or sharpen the bottom of the rudder... your sharpen is indeed my radii.

ROCK ON

Well alrighty then! Thanks!

why cant this guy ever answer a question in understandable english?

[Grimracer]

Racers.. if you need to, read post 21 and then those that follow.. let me know if you understand what we were talking about.

but for 6S

Round the bottom of the rudder is used to "remove lift"... (the bottom of the rudder being the lowest flat part of the rudder).. We round this so the boat will not try to ride on that area of the hardware.

Sailr was asking and a tic confused (I can understand that) about what we were talking about so we made the clarification.. rounding the bottom leading edge.. "this adds lift". We call that adding radii to the rudder and this is used to control prop depth in the corners.

Anything there you need clarification on let me know.

Turn fin!! all I have to say there.

[6S HYDRO]

Sailr took the time to sketch up a diagram all it would have took to answer this clearly for everyone is saying sketch "a" or sketch "b" is what im talking about. That easy

I'm more amused at a 6-month old thread being resurrected.

[Grimracer]

you and me both Bill.. you and me both!

ROCK ON SOCAL ROCK AND ROLLER!

OK, you asked.

Please clarify why it is that every one of your answers needs an interpreter. I love my boat and this has nothing to do with that.

A simple yes or no (to the diagram by Sailr #1; #2) is the answer that almost every individual would recognize.

After 25 years in drag racing (OK, big boats... SORRY!) I still do not fully understand your answers. I would like to, but these answers are what I would expect from politicians.

If it has something to do with speed secrets (and I do understand that) then, just say that... or.. Just RTFQ and answer it!

It really is as simple as that.

Only then, will OLD posts die a natural death...
