Birth of a Race Boat

and reasoning behind the roll bars?

I will go out on a limb, for 'roll' over reasons....

[Geronimo36]

Just ask Sgro

They make a difference ,one driver and crew gets very dead and one Kisses the Boat after a flip, your choice.

exactly. The roll bars are there for some extra protection in the event of a roll over. The structure of the canopy is Carbon Fiber, and extremely durable in a roll over situation, but the added strength of the roll bar never hurts. We also use Kevlar in the top of the canopy and hatches to further protect from a prop strike if another boat was to go over the top of you.

The roll bars themselves are made from aluminum in this case, we have also made them out of Carbon Fiber in the past.

Thanks animalhouse for the cool thread. I am enjoying watching it.

Just curious, has OL looked at using chrome moly tubing for the roll cage instead of alum?

[Ratickle]

Thanks, love this thread.

I didn't say..............yet! I need to concentrate on building something to bolt them to first. Here is todays progress, finished laminating the stringers, tomorrow we will install the bulkheads and have the hull in the oven on Saturday.

That big piece of carbon in the vacuum bag is a solid sheet of lamination we made, tomorrow it will be cut into bulkheads, Joe is checking on the progress, better get back to work.

how are is the roll bar secured to the canopy. do you wrap glass over the roll bar to integrate it into the top of the canopy and does does it get attached to the bottom side and the hull ?

[animalhouse]

The roll bars will be completely glassed into the canopy. They will also be glassed into the hull once the hull and deck are joined.

Great thread! Can't wait to see the boat in KW

[animalhouse]

Glassing in the roll bars and installing bulkheads

[animalhouse]

more bulkheads and a new fuel cell

[DAREDEVIL]

I wonder why u guys and others use the bladder tanks,,,,is aluminum not better ????

bladder tanks dont slosh and most are explosion proof

[DAREDEVIL]

bladder tanks dont slosh and most are explosion proof

Yeah,,,but they brake under the ethanol fuel with in 5 years and my aluminum tank is in my boat since 1991 !!!!!!!!

[phragle]

I havent looked at a score rule book in years, but as it was...all cars had bladdered fuel cells and the bladders had a 5 year lifespan. same with seat belts. Dates were checked at tech. properly built it is no problem changing a bladder in a can.
