I Got Framed at Dirty Nellies....Dirty Nellies little secrets
Some raft manufacturing folks as well as some guide folks loosely use the term tracking to defend the selection of a self bailing raft. Physics proves these folks as ignorant of the forces at play.What they are attempting to do is influence the added expenditure on that expensive self bailing floor.Whereas a bucket boat or occupant bailing boat may be more beneficial to your needs.
Tracking is a characteristic of a raft to stay on track amid the external forces and moments acting on the diaphragm in motion. Newton wrote the book on it; it’s his first law.This is not new science.A raft in motion will stay in motion unless acted upon by some other force.Inertia and more specifically Rotational Inertia is a characteristic of the boat and its geometry.Self bailing rafts have higher rotational inertia and are therefore harder to turn.Self bailing rafts weigh more and require less corrective steering than bucket boats.Bucket boats have less weight, less inertia and therefore are easier to turn.In small technical rivers where turning is essential, I’d opt of the bucket boat without remorse.If my wife is my only passenger, I’d opt for the self bailer since the bailing tasks fall on her.
I see a lot of people waste a lot of money. This is America and it is your choice.
Rigging: Differential currents (eddies) affect your steering.I suggest you exercise the opportunity to rearrange weights about your boats X and Y axis.If inertial properties are not aligned, you may spend additional effort correcting your steering.
Yeah, We Make That....Better and We Make It In The USA
