Hospital Hop...how to stop it?

jeeze... If you guys only knew how much experience, how successful, how helpful, and NICE this guy you’re talking to is and has... I don't think you would treat him or anyone else like that.

Posting on technical discussions on a public forum like this is difficult. You can’t convey emotion, it’s tough to get your technical ideas into words, and you can’t talk to someone face to face.

Everyone take two steps back and take a deep breath. WE ALL are fighting the good fight!!!!

I respect and appreciate the contributions to the hobby by all involved in this forum to include Grim....but I also understand exactly the frustration with the seemingly non or roundabout answers to some of the questions here....been there a few times.

The answers may seem clear to those that post them...but it is (apparently) not so clear to some of us less experienced readers. I'm occasional guilty of losing my patience for the same reason and I apologize for that....but guys please try to keep things a little more clear and simple for us new to the hobby...it would help keep us from being turned off to the hobby.

This is why its hard for me to post on these things..

RC boat racing.. playing.. testing.. … is a tuners game.

If you are willing to take the time to learn tuning and setup its a VERY VERY rewarding hobby..

Maybe im old school but just barfing out info cuz people might not be willing to learn through testing doesn’t do it for me.. maybe just me!…. Give me the simple way out.. just tell me.. is the feeling the boards give.. maybe that’s what they are for.. maybe that’s all they are good for..

Maybe that’s an argument for me to stay off of these silly things...

I have had some very profound experiences testing down at the pond.. most I will never forget... its just hard to get them on the boards. I dig this hobby so much but have not made any buds on the forums (not totally true.. Topfuel443 is a SUPER GUY and I a very good bud.. met him on the forums).. I guess its just me..

ROCK ON and good luck to all!!!!!!!

I believe the hobby has had a resurgence because of the very helpful experienced boaters that share their experiences with the new guys. Everyone has to start somewhere. Those that are willing to share are truly the good guys of boating. When I started in the hobby 30 years ago, there was no such thing as these forums. You had to go to the races and try to learn what you could and hope you found at least one friendly guy.

Yes, it is often hard to get a point across because the new guy has no point of reference and unfortunately probably doesn't have a nearby club, etc. Any time you can add a photo or a drawing it helps!

Thanks Grim and to all the other good guys that help!!

First straight answer I've seen so far, even though it's amidst some chaff. Too bad it took so long to hear (see) it.

This was NEVER about you (Grim) personally; just the manner in which you answer questions. Thank you, I am now clear.

There are so many here on the forum that have been eager to share information, even to the extent of multiple posts, that I may have mistakenly placed you in that category.

I believe you have designed a very fun boat and I thank you for that.

Hey Bob, where in CA are you ? Near L.A. ?; we run at Legg Lake in S. El Monte;
lots of boats there & we need more FE. Know Steve Sharp? A good friend of mine.

Tony,
Will send a PM. I'm about 200+ miles north on the coast.

Not sure I am qualified to miss other boats in a heat quite yet (vision is not what it once was). I can try to stay on the outside however.

I hear 'Ya Bro ! My vision sucks & my mental focus is worse ! One of the funniest
[ stupidest?] things I did at the Nat's last year was to space out at the start of a P-Mono heat & "forgot" to turn at the first buoy

Now cleaned out; re-post.

Here is an interesting patent from the 70's referring to a sponson vent. Apparently, pressure is able to vent out the sides of the sponsons with a small recess on each side. I've seen this on full size hulls at hydro races and people claim it works well to eliminate the sponson dance (side to side). Not sure how it will help us at scale speeds of 400mph or so??


Application Number:05/558151
Publication Date:07/06/1976 Filing Date:03/13/1975

SUMMARY OF THE INVENTION
This invention relates to a four-point tunnel hull for a boat.

It is common practice to so shape the bottoms of boats so that two longitudinally extending, downwardly projecting, laterally-spaced sponsons define therebetween a longitudinal channel extending from the bow to the stern of the boat and frequently are referred to as a "tunnel".

In such boats pressure builds up in the tunnel between the two sponsons, which can be released only at the stern of the boat. At high speeds, because of this pressure build-up, there is a tendency for the boat to ride up on the column of air pressure and then to fall off to either side, causing a "dig-in", "spin-out" or pass and flip backward.

In my novel hull a step is provided in each sponson intermediate the bow and stern. A portion of the pressure is relieved at these steps, so as to avoid the above dangers. The bottom of the front part of each sponson also lies at a sharper angle to the perpendicular than that of the rear part. The deep vee of the front part results in a smoother ride because of the improved entry into rough water. The flatter rear sponsons assist in carrying heavier loads under more stable conditions.

Step or Vent?

Not the same from what I know.. I read both in that post.

If you will look at most of the cat hulls, they are made that way.

I think it has less to do with people looking for a lazy, easy answer and more to do with people not wanting to ruin a $20 rudder.
