I am sure that most boat designers may use a similar formula for their designs as I doubt that they build a whole load of boats varying all the dimensions slightly to give you the absolute best layout. Please correct me if I am wrong here but I do not see anyone building 20-30 boats to determine this.

Measured from the transom:

Rudder = 10% of hull length

Water scoop = 15% of hull length

Prop tube = 20% of hull length

C of G = 37.5% of hull length

Mount the engine al low as possible and have the shaft angle as shallow as possible with the largest... ]]> feeds@yuku.com (Teslaboats) http://rcracingboats.yuku.com/sreply/4324 Sun, 08 Feb 2009 09:34:37 GMT http://rcracingboats.yuku.com/reply/4323/t/hull-Identification-.html#reply-4323 L I N K ]]> feeds@yuku.com (HendricX) http://rcracingboats.yuku.com/sreply/4323 Sun, 08 Feb 2009 07:29:04 GMT http://rcracingboats.yuku.com/reply/4322/t/hull-Identification-.html#reply-4322 feeds@yuku.com (mariangunman) http://rcracingboats.yuku.com/sreply/4322 Sun, 08 Feb 2009 04:41:47 GMT http://rcracingboats.yuku.com/reply/4321/t/hull-Identification-.html#reply-4321

L 900mm
A-495mm(engine)
B-350mm(tube)
C-195mm(propeller)
D-80mm(ruder)
CG 350mm

Dave can you confirm ??

The problem is that i have found in my papers the dimensions for Tempest and this hull is 40mm longer and 20mm wider than the tempest !The only one that comes closer is Lightning!
