Simon - Speeds in CCC 600

Chicken Nugget stated that during practice they achieved slightly over 5 knots or 5.8 mph.
I was fastest (see graph) so this seams about right.

Velociraptor at Henley last year was slightly faster than my Fast 3 and I clocked 7.7 mph max.

I have now scrapped my twin outboard motors and reverted to a long tail system driven by a single 18V drill. In the local canal last Sunday, I achieved 6.5 mph but then slowed down caused by cavitation/ventilation.  This has been a pain this year on all types of drive so I am designing a new series of propellers.

Pete - Races for 2014

I think that to increase the length on the boats for the Tender race is a good idea but hope that you still keep the 36V limit.  This would then allow Velociraptor, Chicken Nugget or similar canoes to race but with limited power.  I would not increase the course length or number of turns as you are starting to get towards the power limit for the drills.
This can be seen on my graph, the speed starts to slow down over the race length.  Also the number of failures of drills burning out would increase.
