Whoever wrote this has a bias – commented Gary Neill of Napier NZ
It is absolute rubbish, he said but unfortunately Gary Niell hasn’t understood the post & subject he’s commented on.
It appears as if he is wanting to establish his professional standing in support of M Pigneguy without getting Facts right
Here is the full comment from Gary Neil plus perhaps the tail end of the previous post’s comment ?
“Whoever wrote this has a bias. It is absolute rubbish. The rules and their interpretation have been tried and tested over generations throughout the world. The type of navigating undertaken by this give way vessel is flawed.
What a load of crap. Having been through both the original Wellington and Auckland Nautical Schools to Master Foreign Going ( or unlimited for those landlubbers) I can assure you it is a failed assumption to use the thumb. Place where you are standing, movement sideways or forward through boat movement throws the bearing out so much the concept is a joke This Bolton obviously hasn’t learnt professional navigation and is a danger to everyone on the water.”
Firstly in response – Bolton is professionally qualified in coastal & celestial navigation since the mid 1970’s – the days before GPS & Radar was common in recreational craft.
He has familiarity with the Auckland Harbour since the 1950’s when he was training at Naval Base HMNZS Tamiki on Motuihe Island becoming well acquainted with the channel across to Browns Island.
He was racing in A Division with character yachts such as Ariki, Ranger, Innismara, Buccaneer, Volante, Fidelis, & Ta Aroha before becoming an international sailor & circumnavigator via the Southern ocean, Cape Horn etc
This Rule of Thumb was a basic requirement used by all sailors & navigators back then & probably still is today unless technology has detrimentally relegated these skills to the subconscious where most people are using it automatically even when they aren’t on the water – eg. Crossing the street, gauging their safety from on coming traffic or dodging other pedestrians when walking in a busy area.
It was thoroughly explained in Court & in previous posts as a Method not involving a Thumb – but just a Line of Sight.
Bolton provided a diagram to illustrate how it equates to a compass bearing transferred across the other vessel to the background. It is more accurate than a compass reading because of the amplification similar to a reading at the end of a spoke rather than at the hub. Several vessels can be monitored simultaneously in conditions when a compass would be impractical or even unavailable – sea conditions do not influence this method & it is infallible, certainly compared with the Relative Bearing used by M Pigneguy which required him to steer a steady course, failing due to the absence of that criteria.
Paul Bossier in his Learn The Nautical Rules Road,
Farwell in his “Rules of the Nautical Road” &
Julian Joy in his Report all validate this method as being navigationally valuable & still taught in the Maritime School these days.
A Diagram illustrating the line of Sight method of transferring the equivalent of a compass bearing across the other vessel to the background. Note this has been called a Rule of Thumb – it does not use a thumb – it is “a rule based on experience or practice” If not known to a navigator, his natural senses & skill must be sadly lacking & it’s a sad day when safety is dependant on batteries not going flat or instruments remaining operative even if circumstances allow their use.
