Adam F Posted September 21, 2008 Report Share Posted September 21, 2008 Rach and I dived the Aeolian Sky today. Was very, very interesting - having fished this wreck dozens of times I had built up a pretty good mind's eye picture of what the wreck looks like. We dived it with a clear sunny sky, yet it was pitch black on the bottom The wreck is quite broken in places and is huge! It's like diving a tower block! You certainly wouldnt want to drag an anchor into it! I can see what it fishes well for eels! No piccies as was a bit dark and murkey, but great to see what the wrecks we fish look like at the other end. Adam Quote Link to comment Share on other sites More sharing options...
just add water Posted September 21, 2008 Report Share Posted September 21, 2008 sounds interesting so did you see many of the long grey things Dan Quote Link to comment Share on other sites More sharing options...
great white Posted September 22, 2008 Report Share Posted September 22, 2008 Hi Adam Glad to hear you had a nice dive. and I am also glad we were not trying to fish the sky yesterday. would not like to have to net a Franklin When do you divers pack your kit away for the winter? and leave the inshore wrecks free. You may be interested in looking at the wreck tours website, I believe the sky is No27. It shows a good insite into what you would see in good vis. regards Charlie Quote Link to comment Share on other sites More sharing options...
Adam F Posted September 22, 2008 Author Report Share Posted September 22, 2008 We started at the bow where the shot was, and moved south along the portside rail down to the accomidation block. Although it was dark, torches made the wreck recongisable... Plenty of eels on the wreck!! There were 4 dive boats yesterday - until the end of Oct the water stays warm enough to dive for most people, so after then really...

Sinbad Posted September 22, 2008 Report Share Posted September 22, 2008 Adam If you fancy a bit of slack tide diving... my Anchor is in Chapmans Pool... Could make a fortune in recovering a bit of ground tackle... Quote Link to comment Share on other sites More sharing options...
Coddy Posted September 22, 2008 Report Share Posted September 22, 2008 Mine is just around the corner of St Albans head towards Chapmans Pool! It is only 9kg plus chain and a bit of rope! Would work well on the new boat Coddy Quote Link to comment Share on other sites More sharing options...
gaffa Posted September 22, 2008 Report Share Posted September 22, 2008 While your at it Mine's on Bournemouth Patch a nice 7.5kg Manson with plenty of chain and and about 30feet of 12 mm anchorplat Re the Sky were there any really big eels there?

great white Posted September 23, 2008 Report Share Posted September 23, 2008 Pete there are certainly some good eels on the sky, and sometimes plenty of them. She is also a good big wreck to practice anchoring and drfting over. That reminds me have you checked which datum your set is using? our numbers should not have been as far apart when you were alongside me a while back.

gaffa Posted September 23, 2008 Report Share Posted September 23, 2008 Charlie, I guess the Eel God is hankering to get to the Sky! I checked the datum when I Got back to berth and found it was set to an English datum rather than the Standard default(Can't remember actual names and don't have plotter handy) Anyway they both seemed to match when I changed to default. I even checked GPS reading with chart and measured distance from end of pontoon to boat and gps and paper chart were identical. The only difference was that the Navionics Gold Chart overlay showed me on dry land . A drawing error of around 20feet I'm using the default datum standard now but haven't been back to check wreck site due to weather being snotty! I was out with my son and grandaughter on Sunday and we had gurnard and small bream but it wasn't very comfortable drifting the patches with the wave heights as they were. Still boat handles the seas pretty well and if wind dies down I willl definately head for the marks you suggested. Pete Quote Link to comment Share on other sites More sharing options...
great white Posted September 23, 2008 Report Share Posted September 23, 2008 I am sure someone will post on here which Datum to use I believe if it is WGS84 positions can be taken from a modern chart. If you have info from other datums corrections are available to change to the WGS84. Numbers that I gave you are defiatly in that datum, so your plotter needs to be if you are looking for something as specific as a shipwreck. It is the standard datum now I believe, so it sounds lijke you are now using it. I have simular problems with the navionics gold in the Yacht Haven, it shows me as driving through the breakwater on the eastern side. I think it is an error with navionics drawing of the marina. When I check with other better documented things in the harbour ie bullpit , parkstone platform and haven post they are all spot on. You are right Dan is always keen on eeling trips, I am sure if the weather plays ball we will be out there soon enough. Charlie Quote Link to comment Share on other sites More sharing options...
gaffa Posted September 23, 2008 Report Share Posted September 23, 2008 Charlie, Yes I can Confirm I am now on the WGS84 DATUM. I will definately recheck some of my marks using this when I'm next out. I couldn't find them before so I hope I will be able to now Managed to Christen my new Fladen Maximus 3/0 on Sunday and was very pleased with its performance. I could even cast with it(although not very far). As long as it continues to perform as it did I will be very happy with the purchase it was nicer to use than my Charter Special and I like that one I'd Like to test it against something with a bit of size and power .(Excluding the Missus) Pete Quote Link to comment Share on other sites More sharing options...
conger king Posted September 23, 2008 Report Share Posted September 23, 2008 ask dick on strongbow he will retreve lost anchors for a small price as he dives every where hope this helps Quote Link to comment Share on other sites More sharing options...
Bob F Posted September 23, 2008 Report Share Posted September 23, 2008 Most paper charts for the UK will use OSG36 as the datum (Ordinance Survey Grid - 1936). The chart will usually say which datum it uses somewhere. WGS84 is the default Datum for GPS's. It's the model used to map the world and is applicable anywhere in the world (if you were in the Africa, OSG36 would be completely inaccurate, but WGS84 would be ok). Many of the older dive sites use OSG36 but the newer ones are moving to WGS84. As a club, we are trying to standardize on using WGS84.

great white Posted September 23, 2008 Report Share Posted September 23, 2008 Hi Bob The newer chart that I checked at work today stated the WGS 84 datum could be taken from the chart. An older chart in a frame in the Clubhouse was WGS 72 [i have not even heard of that one,] I thought it was all 84 or 36 but I know there were loads to select from on my last DGPS set. Pete those numbers should be good now mate, better get to a wreck and test that reel. Tight lines Charlie Quote Link to comment Share on other sites More sharing options...
Bob F Posted September 23, 2008 Report Share Posted September 23, 2008 Hi Charlie It's good to hear that the newer paper charts starting to use WSG84. That'll make it much simpler for everyone. BF Quote Link to comment Share on other sites More sharing options...
Seamouse Posted September 24, 2008 Report Share Posted September 24, 2008 Charlie, Yes I can Confirm I am now on the WGS84 DATUM. Pete Pete, Just a warning note - if you've changed the datum on the GPS, it will have automatically adjusted all the numbers already in there i.e it will have kept the original error. You now need to go through and re-enter all your WGS datum numbers that you had entered under thw wrong datum. Steve Quote Link to comment Share on other sites More sharing options...
gaffa Posted September 24, 2008 Report Share Posted September 24, 2008 ooooooh deary me Thanks for info Steve I'll have to do another download I've probably got around 100 to re-enter. I remember entering the originals by hand but I think I managed to download the majority off my computer using .csv file format. I may be wrong as memory not as good as it used to be. I'll reread the manual to find the easiest way. One way or another I going to make sure they match the marks in future. Peteg Quote Link to comment Share on other sites More sharing options...
Bob F Posted September 24, 2008 Report Share Posted September 24, 2008 That's assuming that the numbers you entered in the first place were orginally WGS84 numbers. If they were OSG36 numbers and you had the GPS set up for OSG36 when you entered them, the GPS will automatically convert them to WSG84 when you change the set up to WSG84. So, do not assume your original numbers were all WGS84 or OSG36. There is probably a mix of both. The problem is that you cannot tell which format the numbers originated from unless you know the original source. My advice would be to keep the numbers you have entered in OSG36, and then enter a second set using the same numbers but with the GPS set for WSG84. You then end up with two numbers for each mark. If you navigate to a mark and cannot find it, try going to the second mark. In this way you will eventually find out which marks have the correct numbers.

great white Posted September 24, 2008 Report Share Posted September 24, 2008 Good advice Bob I bet like Alfresco, joint venture will have a lot of marks in those plotteres when she is launched. Pete if you follow Bobs advice it works a treat ,but remember to delete the false ones after confirming which are the good ones. I had been looking for a certain wreck for a while, I had all sorts of numbers from lots of various sources, the plotter had about 5 positions for it. when we went out it was directly below the third one we tried. the other 4 are now deleted. For my Lowrance I use mapcreate to add the info to the SD card from the comfort of my study,then load onto the plotter later at the boat, There is a free download of a simular pc based system providing your set can read a user card. I am sure Bob will post what its called. Charlie Quote Link to comment Share on other sites More sharing options...
gaffa Posted September 24, 2008 Report Share Posted September 24, 2008 Guys , Thanks for info Would be interested in name of programme if available. Last time I just converted my excel spreadsheet data into a csv file and down loaded it onto an sd card. I followed the instructions to copy the data file into the gps memory and there they were. I need to find the book I used to source the majority of the numbers to find out what datum was used. it will save a lot of petrol Peteg Quote Link to comment Share on other sites More sharing options...
Duncan F (bathclaret) Posted September 25, 2008 Report Share Posted September 25, 2008 The freebie Lowrance utility is GDM 6. You can download it from http://www.lowrance.com/en/Downloads/GPS-Data-Manager-GDM/ ... but you can't use it with MapCreate. It works fine for me - allows me to hold all marks on my PC and read/write an SD card from the plotter in the boat as well as copying to my H2O handheld too. Hope this helps, Duncan Quote Link to comment Share on other sites More sharing options...
gaffa Posted September 25, 2008 Report Share Posted September 25, 2008 Cheers Duncan, I'll give it a go this weekend Peteg Quote Link to comment Share on other sites More sharing options...
great white Posted September 25, 2008 Report Share Posted September 25, 2008 Thats the one, works like mapcreate but its free. just check that the settings are correct for Degrees Minutes and Decimal, not degrees Minutes and Seconds Charlie Quote Link to comment Share on other sites More sharing options...
gaffa Posted September 25, 2008 Report Share Posted September 25, 2008 Guys, I was confused regarding the .csv files As soon as Duncan mentioned GDM6 I realised that was the program I used to get my data onto the sd card. I have consequently reloaded the data into GDM6 and edited it where necessary having been given a couple of modified coordinates from my main mark "source" All coordinates have been confirmed as WGS84 and I will reload them with the gps set to WGS84 on the weekend. Hopefully out for a test on Sunday .If weather as good as forcast will probably head for the Marks you gave me Charlie and see if I can pick up a confirmed wreck Peteg Quote Link to comment Share on other sites More sharing options...
great white Posted September 26, 2008 Report Share Posted September 26, 2008 Hi Pete I am sure you will now be fine, especially as the numbers I gave you are from my lowrance and are definatly WSG84 and DMD. I hope to be out on Sunday and maybe in that area returning from Weymouth, give me a call and if we are close enough we can check numbers again Tight lines Charlie Quote Link to comment Share on other sites More sharing options...
