cruising log?

Two questions, really. I'm learning navigation, putting it into some
sort of practice by sailing my Heron dinghy on pre-plotted
mini-cruises.

Question 1: what would be an average speed for a Heron in calm sea
conditions - I have no idea, I just sail it!?

Question2: Is it worth getting a trailing log of some sort? Question 3
in that case - where from/make/type?

Help appreciated...

Re: cruising log?

Don't bother with a trailing log, a cheap GPS will be easier to use and offer extra facilities.

In a calm sea (little wind) I would expect 0-3 knots. If you can find a sheltered patch of sea with a good breeze maybe 10Kn.

I'm not sure if anyone still does them. The Walker's Knotmaster is
gone - perhaps the Wasp is still around.

If you intend to learn navigation, a GPS doesn't really cut it to
develop your skills. Especially in the Channel, you really need a log to
check for currents, plot calculated positions etc.
All electronics brake down. If a GPS is your only way of telling where
you are, you are laying too many eggs in one basket.
All imho, off course.

It can still be found in antique shops at ridiculous prices.

As the heron is a mirror sized dinghy with a traveller and rudder taking up the transom a trailing log is just going to end up as knitting.
You don't have to use the GPS for position fixes if you want to practice navigation, but it will give yo your speed over the ground.

All this shroud waving about electronics is bunk.

I have not been on a boat for 20 years that did not have electronics for some/ all of its navigational aids. And I have only ever had 1 electronics failure, the battery fell off!. But there are those that will say if I used semaphore it would not have happened.

Fell off the handheld VHF (Not the boat) ;-)

quid you can buy two GPS's so failure is unlikely. If the whole system goes
down we're all in trouble including the RAF!

I got a Knotmaster as a backup for my 3 GPS units but the trailing end
fell off in a F8 in Biscay. Luckily all GPS units still worked so I
could plot a position.

But then again, I only paid 20 for it. Some people really want to get
rid of theirs. Now I know why.
