Life Jacket:
If racing outboard hydroplanes CBF spec requires life jacket with 'tail'. This is to protect your back/butt/spine in rare event an engine grenades forward toward drivers back.
If racing outboard T class, CBF does not require life jacket with 'tail', which is also uncomfortable to sit on in T race seat.
I race both classes, I designed and had Lifeline make a suit with removable tail(~10"x 20") suitable for either class.
Cut Suit:
CBF rules do not dictate requirement or preference for 2 piece pants & sleeves over 1 piece overall.
All those I have seen in hydros or T's has 2 piece, whereby upper part only has cut proof sleeves(torso is nylon), and whole pants are cut proof material.
I know only one person in our racing community ordered a one piece cut suit, ~U$1K+, its all red, he's a big guy in Drag.
He never wears it because he said he looks like a big walking prick, a bigger prick than he is already.
On hot days it chafes him and figuratively everyone around him.
Canadian Boating Federation is the national sanctioning body, all CDN class racing rules are posted there under General Racing and specific class rules. Take time to read & familiarize:
http://www.cbfnc.ca/resources/rules.htmlAt the end of the day, it is each drivers sole responsibility to inform themselves and know applicable rules, same as per rules of the road.
I hope this helps.
PS: not relinquishing names but the Biig Drag guy is like a big red sausage in his Yellow Bun Boat, 'Alice's On'.
I swear, like an Oscar Mayer sausage van on water, until it spills, mustard, relish, ketchup, Big Sausage, flying everywhere. Eco disaster.
I better hide.
