thats wot Tranona said
It's not really, he just said the waypoint can be used for two things. What I'm saying is that one of those things essentially removes most of the useful functionality of the electronics because you can only use one waypoint at a time. Having invested in the electronics it seems odd to use only a single piece of functionality. It's like using a computer only to type letters on, it works and is slightly easier than a typewriter but is rather missing the other million things a computer is capable of.

Why is it wasted? If you only have a hand held there is no reason why you can't put in the rose centre as a waypoint and just do a GOTO when you want the range and bearing to plot your hourly position. That is what I do on say a Poole/Cherbourg. Waypoint to steer to is CH1 or Poole Bar buoy and rose for plotting regular positions. Like Sailorman I would steer a compass course derived from my tidal offsets. Chart shows the usual S curve of track and GPS with destination waypoint showing the XTE.
All the key information captured and recorded with the minimum of effort and little room for mistakes. These days I have a PC plotter as well as two GPS so I have a running position electronically, but still plot positions on a paper chart using the rose as a waypoint on one of the GPS.

Looked at the number of posts so I thought I had better watch the clip.
Nice simple method, take the position, turn the GPS off until you need another position.
Cannot understand why peeps would want to argue about it, if only one person likes and wants to adopt it then it is of benefit.
If you use another method then list it but please don't rubbish a method that works.

apart from the marker pen it is the same method as i use, my battery pwr is adequate enough to leave the gps on all the time.

It's not a case of arguing. The OP said he had a simple and safe way of doing something. If he wants to do it that when then that is also fine.
However, he posted it on here. That puts it up for comment and criticism. Personally, I do not think the method is any simpler or safer than other methods I have seen.
It's not rubbishing, it's healthy debate.

a waypoint does not need to be a By, it can be where ever you want it.
why fight the tidal flow by doggedly travelling in straight lines when one can use the tide to ones advantage thereby travelling less distance.
why do folk have to go & read whats written on a By

Thanks theguerns for sharing this simple method. It is easy to do and carries less risk of making a plotting error (as long as you wipe off the previous marks from the straight edge)

In fact, better hadn't be, especially if you have a fancy integrated autohelm system
I was once on board (down below, making tea, disclaim all responsibility
) a yacht that steered itself right into one of the big steel channel buoys in the western Solent, that had been set as a waypoint.I know Dylan's all right though, as he doesn't have a fancy integrated anything (except possibly lighting and heating systems, his little tealight campfires).

that is true
after my eyes the most used navigational aid on Katie L is the peastick echo-sounder

Thats how the Cast Iron anchor was broken last w/e

I've seen the video and read all the posts but I'm still confused as to why he does not just read the coordinates off the GPS and plot them directly onto the chart?

because
1/ less plotting
2/ therefore less chance of error especially in heavy conditions
3/ its quick & any crew could do it

Thanks theguerns, good video. There is a lot of merit in keeping plotting simple on a small boat.
No doubt those with negative comments will be producing their own instructional video contributions.

we were both talking about very similar ways of the system
.
i hadnt seen the video
he failed to see what i & Tranona were talking about

Thanks Sailorman - I'm sort of beginning to get it.
I'll have to try it for myself.

i use one handed dividers as i had not considered the pen.
certainly do not use the pen on the chart as per the video
i make the distance / bearing lines cross & 90 deg, then mark time one side of the bearing line & distance run on the other side.
then "all nav on chart"

This photo shows a trip Harwich > Oostende.
there is the goto wp shown as the straight line
then the curved line is our actual course, shown on the plotter but sailed by compass
the latter is the shortest distance possible,to sail approx 72 / 73 Nm

That's what happenned when a ship hit the Nab wasn't it?
