What's the Coaming Side Rule Status

[kws]

Tod GReat idea!! i have to add about 20 pounds to my A boat so think i will come out ahead after all the weight is added to the boat for bat. computer + actual hardware for said air bags at least compared to many a drivers lol
question: the rule(UIM) is really 250 cc and up + osy400 is it not? how fast do 250's go on a big course?

UIM Rule

The UIM rule for 2008 is for 0-125, 0-175, 0-250, 0-350 and OSY-400

[QUOTE=jsilvestri;97223]There has to be plenty of testing data because the OPC catagory has required impact certification for some time for those who build capsules. ]

exactly those drivers are restrained, with helmet restraints, inside of a capsule that tends to get spit out while the rest of the boat self destructs

Mark, those classes all have at least record speeds in the 80's. is this correct?

My point being is that there is data from tested composite panels. Each boat builder who builds capsules has to be certified. To be certified the boat builder has to make a composite panel of the materials they are going to build the capsule from and then have it sent off and stress tested. I do not know who does all of this but this is the process. Now, these tests are what I am referring to as test data.

My personal opinion is to have some rule for rounded pickle forks, which could be done to all existing boats and to all new construction and leave it at that. As far as reinforced cockpit sides, leave that up to the individual. My CSH has rounded pickles, composite cockpit sides, composite floor board and a composite windshield and I am happy. If another driver does not want to do that then fine. To each their own.

im not at all opposed to rounded pickels, i tend to think we should take it a bit further. if the pickels (and the spears on runnabouts) had a 6 to 8 inch crumple zone. it would absorb a tremendous amount of energy no matter what the boat hit.

Ziggy Boettle does the testing for cockpits. I had one done
useing the layup recommended in the Pro rules this achieved 2100 nutons. 2000 is one goal for some OPC capsule boats and 3000 is goal of larger ones,as Pro capsules boats are only about 200 lbs un rigged the commossion has accepted this. Ziggy gets $75.00 to test a piece you must make it to his size for testing . This info can be found on APBA'S webb site. I will ask the pro commission to fund several different layups for Bill Giles as he would like to test several.

just curious

what is the typical total weight for a 350 hydro rig including driver? what is a typical competition top speed for this class?

how about for 700 hydro?

thanks,
Bill

Weights

A typical 350cc hydro, rigged with driver is probably around 400 to 450 pounds. The speeds for that class are about 95 to 99 mph.

A typical 500cc capsule boat, rigged with driver is probably around 500 to 550 pounds. The speeds for that class are about 110 to 115 on the short courses.

125cc runs what, upper 70's on a decent sized course?
