C & C 35 Class Measurements
One of the goals of the C & C 35 Association of Detroit is top provide level racing at an affordable price. In order to facilitate this goal, strict measurement standards are maintained. The following pages provide measurements and notes related to class members. The data is primarily the work of the class measurer; specifically, Brian Geraghty.
A. Configuration – Weights are with full fuel tanks, No equipment (unless bolted in) and with cushions.
B. Scale Correlation – The BYC Strain Gage Scale was compared to the Class Scale (Dillon Dynanometer) at low and high weights and found to be comparable. The difference was less than 1% at the weight of the boats and frame.
(a) Class Scale BYC
Frame and wet straps: 875 +/- 25 840
Contender & frame & wet straps 12,000 12080
C. Issues Noted During Weight-in – Lexan noted as having feathering two bladed prop; considered a disadvantage.
D. Average Weight Active Boats (1997 season) – 11,289#
E. Average Weight All Boats – 11,256#
a) Dimensions (lower band, upper band, spin halyard hoist, spin reach)
b) Sections ï¿½ air flow
c) Top Design
a) Dimensions (E, OAL)
b) Shroud span
4. Spin Pole
a) Spin track range and hoist on mast
b) Measured length
B. Keel section
1. Section maximums
3. Calculations of thickness and weight
D. System Measurements
1. No equipment weight
2. Tip test (Timing)
3. Alternate equipment that would affect weight ï¿½ note & estimate impact, e.g. batteries, stove, tanks, head (ceramic stock), vang, boom, floor
IV.Stability & Predicted Speed
