Sport 40 strut mounting

[Joe Wiebelhaus]

The rule says:

4. Hull shall be a minimum of 35 inches and a maximum 40 inches in length.

Thats the hull !

WOW Another 5 pages on this!!! I sure hope the select few up there in Canada sure feel special. We will be voting on a National rule just so a handful of racers that purposely built their boats "outside the rules" can race in a class that their boats don't qualify for. Now for those who think I am being to harsh on this, there is a class that a sport 40 style boat with the transom mounted strut can race in and that's 40 Hydro. There problem solved!!!!!!!

This explains everything.

I just don't see the need for a national rule change for a select few who didn't build their boats to the rules. If you want to allow these boats to run in sport 40 then put it on your fliers. All it takes is an asterisk next to Sport 40 on your flier and state " transom mounted struts are allowed". There is no need for a national rule change for this.

Buddy, in my post from last night, I said the ACTUAL HULL LENGTH could not exceed 40" per the either version of the rules. I also said that with the strut mounted on the transom, the EFFECTIVE LENGTH of the boat could be as high as 45" rather than the 41" allowed in in the present rules. There is a big difference in actual and effective lengths as they are not the same

 

[sebastiencaron]

I gotta chime in on that one, The boaters in D1 in quebec don't come to even any D1 races. I've seen only Luc White twice and guess what, He does not run sport 40. Tom Galdys

Please Tom, inform you before writing statement like that. You, how many event did you go in D1 this year?? Don't worry, our member don't be affraid to go at other event in D1 to race with other Sport40. I'm a bit disappointed about what you think, we are in the same district and it make me think you don't want us in the IMPBA.

Buddy, some of our boat are about 15 year old and they built like that. If we allow this rule, everyone will be legal without any modification, but if we don't allow this rule, some member will need to modify there boat. I will be the first to don't make this big mofification on my boat. Honestly, did you make a big hole on the bottom of your boat? And by the way, we don't have a rear acces on our boat.

I have built 4 sport 40's for my son and have built several other sport 40's for the guys in my club and YES I have cut a 1/4 inch wide by 1.5 inch long slot in the bottom of the boat for the strut. Then cut the strut off so it is even with the transom and the drive dog is one length past the transom. All of this takes about 15 minutes. I also need to add that before I build any boat I look at the rule book and see if it will be legal to race. I would be very ticked off at myself if I built a non legal boat.

My problem with this rule change is that we will be changing a national rule for one group of racers. Like I said in the above statement all you need to do is put it on your race entry fliers that you allow it and the problem is fixed. No need for a national rule change.

 

[Randy Rapedius]

Yep ... blame CANADA. (rolling my eyes)

LMAO ... you have no clue Buddy. Try looking at the BIG picture. Don F said it best in his posts.

 

[Grimracer]

I think he (Buddy) has a clue.. thats not fair to say Randy. The entire Dist 14 area is VERY strong in the S-40 class. Truth is its some of the best S-40 racing I have participated in. Dang good racing! Dist 4 is not too shabby either! Some great racing there as well.



(you have to see the Joe Kratkey tribute run video from this summer to get a good feeling for IMPBA sport 40s and the people that are passionate about this class)



Here is a link










I too am opposed to this "Rule Change Idea" buy am willing to vote and accept whatever outcome comes forth. And I feel Buddy might have said it best.. The rules were in place or at least IMPBA set rules in place. Boats were built despite this and or in lieu of this. Either way.. they are not legal according to the current IN PLACE IMPBA rule.



Its just not grey to me at all.



Buddy is adding that he feels it’s OK to race boat with the strut on the back so as it is stated in the racing flyer. (that seems fare and like he does have a clue, to me). I particularly don’t subscribe to this thinking but OK. Buds just trying to make it work (looks like it can) for all "With the current rules".





Thanks

Grim. Let me rephrase that.

"You are COMPLETELY missing the point Buddy"

Is that better? No need to answer Buddy. It looks like you have Grim in your corner.

I don't have a horse in this race and I probably shouldn't even be posting. However, since I managed to "jockey" home a winner(that, of course is just my opinion) when I wrote NAMBA's current Nitro Sport Hydro strut rule the following quote from well respected I.M.P.B.A. member seems very germane to this topic.

"If you always do what you always did, you'll always get what you always got."

Call me lazy if you want, but I find it easier to mount a strut on the outside of a transom and make strut adjustment. And, at my age making things easier is a good thing.

[Grimracer]

Randy.. I have always been on the side of.. I see no need to change the strut cuz truth is the racing/outcome will not be any. better.

I do however ALSO have this opinion.. If we (the members of the IMPBA) feel a sport 40 that has the strut on the back (that is and more closely follows.. read in "scale of sorts" is viable to the IMPBA.. THEN.. I AM IN.. champion the class and make it grow. if its better then what we have now then the current boats will go away and the new one take over. Until then I can not support the strut change.

I happen to REALLY LIKE THE "Scale sport" Boats from Dist 1 BUT.. they are just not legal barring our rules. Neather are some other cool looking hydros I have seen.

that's it from my side of things.. lets vote!

Does anbody really believe that sport 40 class is shrinking or suffering because of a strut rule... lets just examine this falsehood.

It is a fact that there is more classes available in the last 5 yrs - .12 classes , .21 sport, electric classes and gas classes - the fact is the money is spread over many more classes than it used to be.

This is the same reason for the ups and downs in membership and classes is do to the options available to the rc hobbyist. I saw the same thing happen when I raced rc cars then it was trucks , then pan cars then touring. and the list continues monthly. a lot of it also depends on the area you are in and the strength of the economy and what people have options to do in any particular area.

Hanging a strut off the back is NOT going to make any difference to the people who really want to run sport 40 class - the way I look at it , if you cant put a slot in the bottom of your boat how do align a drive line or mount an engine - I'm not sure about everybody else, I am not fooled.

I do concede however that will make it more inclusive to other sanctioning bodies and easier to build and look more like the full size boats we are attempting to emulate.

I am not really for the outside mounted strut but will have to wait on the vote and see what happens

flame away but you better bring facts :lol:

Great post Mark.

I don't think the current rule has caused the class to shrink but I do believe the new rule will help it to grow and at the very least bring parody to another very large organization that is already mounting them on the transom.

You do touch on a great point and it's something IMPBA as a whole seriously needs to look at and that's the number of options now available for racing.

I personally believe it is the number one reason that club racing is dying, how many mixed classes are we running now just to make a heat?

We have watered down the racing so much at the smaller events that people just aren't excited about racing.

You got that wright Jerry!

Also I do agree that we now have too many classes. Some members are converting their nitro sport 40 to electric. Wow! Are we going to have the same issues with the strut in that class?

Nobody is imposing that the strut be under the hull or on the transom. Just give a choice to the people that are building new boats.

 

[Blackout]

Curious, what was the original intent in requiring the strut to be under the boat in IMPBA?

I would imagine some hulls perform better with the strut on the transom and some perform better under the boat. I was at a friend's shop the other day and noticed one of his gas sport hydros had the strut under the boat. He said it was a "secret" recommendation from the boat designer.

copied from the rule book:

2. Hull must be a three (3)-point hydroplane configuration and resemble a limited or

unlimited hydroplane design of past or present, except outrigger, modified outrigger,

tunnel, or canard hulls are NOT permitted.

So if we take this rule that Mark just posted the rule does not need to be changed in order to run a transom mounted strut as most of the new boats we try to resemble run a transom mounted strut. Thank you Mark. Case closed.

[Hydro Junkie]

Actually, Dave, the rule in question has to do with the location of the strut. Per Section H of the IMPBA rules:

Sportsman 40 Hydro (Sport 40 Hydro)
Boat Specifications
1. Boat must be inboard powered.
2. Hull must be a three (3)-point hydroplane configuration and resemble a limited or
unlimited hydroplane design of past or present, except outrigger, modified outrigger,
tunnel, or canard hulls are NOT permitted (this was included in Blackout's post, quoted above)
3. Boat must have a name, sponsor's name, logo, and/or a racing number affixed to hull (a
local, national, or fictitious sponsor name is acceptable).
4. Hull shall be a minimum of 35 inches and a maximum 40 inches in length.
5. If the bow is recessed behind the tips of the sponsons, that recess shall be no larger than
25% of the overall length of the boat.
6. Boat must have a driver and/or simulated enclosed cockpit.
7. No part of the strut may protrude behind the transom of the boat, or have a width greater
than 9/16 inches or a length longer than 3 inches (this is the rule being discussed)
8. See Sport Hull pictorial for clarification.
