Although This Book is really designed for merchant shipping, there is a lot of good information here for anyone new to the concept.
[/ QUOTE ]Wow, at £40 the pair (principles and practice) these have to have something pretty special, to cover a pretty simple subject?? /forums/images/graemlins/confused.gif

A proper MCA passage plan is apparently far from simple. I was discussing it with a ship's captain last year and she told me that it takes hours of work and is so onerous that it's hardly ever done! A text book will of course tell you how it should be done.

[/ QUOTE ]Tis all a question of context. If we are talking BIG ships, then there a lot of complicatoins, turning circles, depth of channels... which we hardly worry about (we worry about depth like we are careful going downstairs - BIG ships have to get it dead right!). For example, in my £50 copy of Admiralty Manual of Navigation, Vol 1, 700p - pages 299 to 315 are devoted to actual passage planning!
** when did you ever have to calculate wheel-over point, advance and transfer or DNC in a sailing boat of less than, say, 16m?

The taster pages accessible via Talbot's link show an interesting example of risk assessment on page 19 and a thirteen point passage planning checklist on page 22.
The risk assessment considers that failure of the GPS is a very substantial hazard, and lists 7 measures to be applied, to reduce the consequent risk of running aground, when passing Baife point light in the Strait of Bab el Mandab, including "Position point fixing interval to reduce to 10 mins". Hmmm. Makes those who advocated, in a recent thread, plotting position on paper charts every hour seem casual, if not reckless.
But the checklist is great. With a bit of modification, it can be adapted for use by the modern yachtie. I suggest converting the 13 tasks into 5 simple steps:
Step 1 (tasks 1-3: confirm destination, establish route, calculate distances). Get out chart and pair of compasses. Draw circle of 30 mile radius around present position and select destination based on ease of access to a pub that serves real ale. Enter waypoint for destination onto GPS.
Step 2 (task 4: collate Company, Master and charterer's instructions). Persuade crew, SWMBO, etc that destination and route have been selected with their needs in mind - good views, food, shops or what have you.
Step 3 (tasks 5-7: collect general information, cargo information and charts). Make sure there's enough booze and diesel on board for the planned trip.
Step 4 (tasks 8-11: identify and mark hazards on chart, lay off course, conduct risk assessment for each hazard). Enter waypoints a few metres clear of things on your route that you'd prefer not to hit.
Step 5 (tasks 12-13: allocate resources for bridge team management, continuously monitor ships' progress along the planned track). Don't forget to take the wheel or tiller before you say "Anyone fancy a brew?" Ensure plotter's cockpit display or hand-held GPS is working, and take a look at it whenever someone says "Are you sure we'll be there by closing time?"

Sooner or later, there will be someone on 'ere whinging-on at great length about the MCA 'doing him' for causing an expensive incident and having nothing on board which could fairly be represented as even a 'half-assed stab' at a passage plan.
For yotties, it's certainly not onerous. Recreational aviators need to file a detailed flight plan and wait for a response. We don't need to file anything - just have a 'back of the fag-packet' outline very loosely in accord with SOLAS V, focussed on the hazards and how to avoid 'em. Big deal!
Them wot can't be bothered, line up here for a Darwin Award nomination.

... not so (most of the time, anyway). The times that (written) flight plans are required are i) going "foreign", ii) a flight within class A airspace (ie. a "controlled" flight, which is essentially IFR), and/or IFR flight in other airspace. A flight plan must be filed by radio before an entering such airspace as a result of a change of plan, diversion or whatever, and (more commonly) permission must be sought (again by radio) before entering airspace other than class A (eg, the controlled zone around a controlled airfield).
It is entirely possible to bimble around quite extensively without using radio at all, nor giving any notice of where you might go (or indeed, even deciding where until you are airborne - and then it is quite reasonable to change your mind!)
- as long as you don't enter any kind of controlled zone.
There are certainly vintage types flying regularly that don't even carry radio...
