Over the next year GigRower will be discussing some of the science behind Gig Rowing.
Through series of tests, analysis & discussions we will be looking at some of the following:
Gig Weight :: How much does your boat weigh?
Gig Rower is purchasing some ”Digital Gig Scales” that will be available to accurately weigh gigs. We all know that our boats get much lighter if left out the water, but how much? Do dedicated race gigs really weigh that much less? If you are interested in weighing your gig then please email Toby.
Gig Hull Speed :: A gigs hull speed, some science.
Maximum Hull Speed or Displacement Speed is a term used to describe the maximum hull speed of a hull. To calculate a hulls maximum displacement speed take the square root of the waterline length in feet (32 Feet for a gig = 5.67) and then multiply this by by a fraction between 1.3 & 1.5. (For a gig say 1.35) and you get a theoretical maximum hull speed in displacement, about 7.6 knots. The variable fraction is dependent on the underwater profile of the vessel. We will be doing some practical on water testing to calculate how much energy is required to increase a gigs hull speed by each increment and what we can do to effect maximum hull speed.
Gig Trim :: Weight in the bow, why do you need it?
Trim describes the movement of weight for and aft in the boat, this has an effect on the underwater profile of the boat presented to the water. Do gigs miss the weight of a pilot in the bow? Does a gig run better with more weight in the bow? We will be testing on the water to find out and discussing the findings.
Gig Rowers :: How much does weight matter?
In sliding seat rowing a rowers power to weight ratio is key. Arguably this is less important in Gigs? We will be looking at how much a crew weight effects a gigs speed.
Gig Stroke :: The perfect stroke …
GigRower is working with Gavin Saunders from Helford and Jeremy from Flushing & Mylor to look at data recorded from a clever little box that Gavin has developed that measures acceleration and power during each stroke. It helps us look at what is happening to the gig during the stroke and why certain techniques (Such as arms away) help your gig run faster.
As well as the above we will be discussing a range of other topics and posting our thoughts on GigRower. If you have some thoughts on any of the above then drop me an email.
