Question and answer
The rules state that the boat must float and not sink. It doesn't say what materials to use, how much or their locations like in the old EP OPC rules. What do I use?
Under the old OPC rule the boats still sunk. Most used blow-in foam or inner tubes. The foam blew out of the boat when the hull broke up in the crash and the tubes either came out or got holes in them during the crash and lost their air. Within a couple of years with no crashes the foam would become waterlogged, heavy and useless. We have suggested foam filled swimming pool bags in a previous post. They work! Don't use air floatation. As for the amount of material, if you look at your life jacket and the amount of weight it can float, it is safe to say that floatation equal to 4 extra large racing style life jackets would keep the boat afloat.
The required amounts of "foam" for floatation is listed in the 2011 rules...see page 14 paragraph 19-B-2 of the rules. It does not state how or where it is to be attached. The 2012 rules make not reference to T class what so ever from what I've read so it must have been an open class last year
19-B-2 states: Every boat must have adequate buoyancy to ensure that it floats in case of an accident.
To LC's point, how much, where and how to affix?
APBA OPC Formula V Pre-race Inpection rule 7C Foam Requirement stipulates:
- up to 13': 6cuft
- >13': 8cuft
Ryley's Critch has (4) foam filled pool bags, 4'x.5'x.75'= 6cuft of floatation. These were prepared and installed by R Scythes, installed after the boat sank at GH 2011, raced w/o floatation. Lesson learned.
Problem with 19-B-2: has anyone tested 'adequate' buoyancy with their boat? Doubt it.
Why a minimum floatation spec:
- If roll over, driver trapped (eg: rigging/other), boat doesn't sink
- Crash with another boat, driver unconcious, roll over, boat doesn't sink
- IF it were to sink from inadequate buoyancy, no one wants to waste time fishing the depths, or have it dwell under the surface as a hazard, leaking fuel to surface. Remove wreck immediately from course, resume racing.
- So widows, orphans, don't sue TORC/CBF/Execs/Inspectors, my fat naked ass.
PS: until 2012, 2013,.... 2025 rules are posted, the last published rules are in effect: 2011.
