Topic: Boat SPEEDOMETER


wilfred2    -- May-19-2015 @ 7:15 AM
  Hi everyone, I am a newcomer to the Forum so here goes.
Does anyone know of a reasonably priced GPS boat speedometer. I have scrolled through the internet and the only ones I can find are very complicated with features I just don't need and a bank-busting price tag. I just need a simple device to give an accurate speed indication up to 10mph. Many thanks and happy boating.

John.

  Wilfred hi,

I can't talk from experience but I wonder if one of these cycle speedometers will do the job.

Try clicking here

SORRY. INVESTIGATED FURTHER AND WILL BE NO GOOD AS DOESN'T WORK BY SATELLITE.  Confused

I don't know but if you have a smart phone I wonder if you can get a suitable apps. There will be other forum members far better qualified to answer this question than me.

Kind Regards
Alan...

  Hi Wilfred,

As boat-mad has said, if you have a smart phone then the "Boatie" app has a GPS driven speed indicator - I have it on an iphone, don't know if it's available for other devices, but something will be I'm sure.

There are 10 types of people in the world; those who understand binary numbering and those that don't.

  I have used both Cycledroid and Move-bike computer apps on my phone to measure boat speed. Both free downloads from Play Store. Both also work on the bike!!

  John, we use a Garmin eTrex and it does the job perfectly without the need to sell a kidney.

A brief scan of eBay shows that they can be obtained brand new for around £60. You may actually drop on a second-hand one for much less. Good hunting. Smile

  Have a look at this:-
GPS
I use one of these and they are great. They 'draw' a
track of where you've been and you can add named
waypoints as you go for later reference. Speed can be
set in Knots or Mph.
All the info is saved even when you disconnect it.
You don't need an antenna if you have clear upward
'vision' as the unit does have a built in one anyway.
I just plug mine into the cigarette socket and off
we go.

  just wait for a member of the public or a ranger to tell you to slow down.......

serious though they play store has an app called Cycledroid and Move-bike which are spot on

  For Android an app called Sail Droid gives GPS speed and compass heading in an easy uncluttered display. I also use GPS Essentials. This has a dashboard which can display all sorts of information including speed. Both good apps (IMO).

  Hi

At the risk of being shouted at try an oldTom Tom or garmin road satnav if you have one.

I have two which read accurately down to walking pace  with the added bonus they show you the nearest eateries as you travel along.

The rivers are a bit schematic but if you wa t to save money you can easily put up with that.

Good luck

  I second the Garmin eTrex as it works well at slow speeds.
On the iPhone i use a couple of apps called  Speedpro & GPSLite again they work well at slow speeds

  We also use the sat nav from the car. Its a Garmin Nuvi, shows speed over ground to a tenth and the trip log gives distance travelled, average speed, moving time and stationary time. The maps are a bit hit and miss but once you've been up and down it shows where you've been pretty accurately. Only cost a new lead and mount.

One point, which seems to have been overlooked, but which is, IMO, very important, is the ability of whatever device you use to display your exact location as a map reference.

I use an old Magellan 310, which is no longer available, unfortunately, but, as well as giving an accurate indication of my speed (to 0.1 mph), it also gives me my location in a user-selected format. I have it set to give my TG location. This is extremely useful, when reporting any incident to Broads Control (obstruction to navigation, collision, etc), and, more importantly, for use by the emergency services, should something more serious happen.

It so much easier, and more accurate, to read out the TG reference, rather than trying to explain 'I passed How Hill about 10 minutes ago, heading towards Ludham Bridge'. Even more so for people not familiar with the Broads and who might not have a very good idea where they are anyway.

Just my two-penn'orth.

  Going past the Rangers mooring at Irstead the other day an Auxiliary Ranger appeared and gestured to me to slow down. Glancing down at my GPS it was reading 3.8 mph.I put up 3 fingers then 8 fingers to which he pulled out a radar gun from behind his back and pointed it at me ????
    LOL

  Hi colingy

I think your experience opens a whole new issue. My understanding is that the speed limits are arbitrary but are mainly to reduce wash and backside erosion.

As some boats create more wash at 3 mph than others do at 10 mph I can easily imagine a scenario where a ranger asks you to slow down ( in effect cut your wash ) even when you are  within the speed limit.
It has certainly happened to me on a laden mayland 16 on the bure. This has a semi planing hull and can create a disproportionate wash. It has never happened to me steering a river boat.

I can't explain the speed gun though that seems a bit odd. Also I don't know your hull type but I put my theory down as a possibility.

Paladine    -- May-20-2015 @ 10:53 AM
 
I saw the Really Ranger using the radar gun in the same place several weeks ago. I was doing dead on 4mph, had it pointed at me, but no waving! I slowed down and had a quick chat. It's their new toy. Battery operated, it doesn't need an umbilical power cord attached to the patrol launch, so we can expect it to be used with the launch tucked out of sight!!!

Of course, that will be of no consequence to those of us who stick to the speed limits   tounge-in-cheek

  I have an old Tom Tom sat nav and it works fine and very accurate. I also think that due to the narrowness of the river through Irstead that the speed limit should be 3mph as it is at Belaugh. The river is no wider at Irstead than Belaugh so why not the same speed limit?

  With no flow on the river and our hull design (Bermuda) there was no sign of wash at all  boat-power

  I have a chart plotter on board so no problem for me but on my android phone (old galaxy ace) I have a free app called MMtracker which will use the memorymap os 1:25,000 broads map to show my location as well as being able to show speed and position in various formats, the mapping came from a one eyed chap with a wooden leg from the coast of somalia, had a lovely parrot too....

  Try this free app. Mad Mutt Marine. Put together by an amateur sailor on the South Coast. Gives you all the data you might reasonably need. Works on proper boats too!
