Hi djh, thanks for that. More variables to try. Yes I do use vane mode but not since I noticed the problem (it is winter down here, very cold and wet at present). From memory the numeric XTE on the plotter and the display are the same - which means that the display/pilot unit is getting the...

Hi David, It has been happening even after it has been happily heading to a waypoint with zero XTE (in a tidal area) for some time (hours) - you will just see that its XTE starts to build. You have given me something to check as I don't normally fiddle with the +/- 1 or 10 when it is heading to...

Hi JohnPhilip, No - my problem is less dramatic, and don't forget that my gear is all Raymarine, taking Seatalk1 (not NMEA 0183 as I guess yours is?). When I tell it to track to a waypoint it does so, nicely, but over time I can see the XTE building (it should be near 0.00 in ideal conditions...

Hi FulmarJeddo, I'm not sure what you mean by "cycling" through locked heading etc. Unless you press "Disp" to call up each display it only shows the one you have selected - but yes you can select each in turn. It is misbehaving in Auto mode, heading to a waypoint, that the XTE progressively...

Hi, I have a venerable Raymarine ST4000+ Autopilot (connected to a SL631 chartplotter, a tiller pilot and ST60 instruments via SeaTalk1). When heading to a waypoint the XTE sometimes continuously increases (instead of staying near zero). This occurs in any conditions (light or heavy) or under...

Hi Angus. Re the AP remote (wired). You may recall that I have altered your original to add a third button Auto/Standby (it needed a wire connection on the PCB and simple code changes). One might be able to add a 4th button (eg MoB) but I haven't tested it. I'm still keen on: a) a...

As with most things it depends what you want from it. I want maximum range to detect and be detected (my family watch my progress on Marinetraffic.com even when 20+ miles to sea). The better splitters are powered and actually amplify both the AIS and VHF signals so neither suffers. My antenna...

RobF makes a good point about asymmetrics (ie my usage) not having the problem 'cause they have tension in the luff. Rather than clipping the sheet and guy down can the same be achieved by dropping the pole slightly, possible as far forward as poss, and securing it with the downhaul? Andrew

Is this the first time you have used it and could there be an issue with its set up? Can you find somewhere to try it out (horizontally) on land? They should (and do) go up/down easily. Keep a little tension on the slack part of the reefing line as you pay it out and, as said before, a...

For Mud Map read - Chart-let or Anchorage Diagram Hi Fisherman, et al. I have all the electronic charts on my Chartplotter, PC, iPad and iPhone for my personal use but the problem is that I would be breaching copywrite to capture the screen and copy/distribute/publish it (in paper or...

Very helpful and should track down your problem - but also ensures Raymarine get your business rather than switching to another brand . . . Re battery voltage, that may be an issue but I would have thought that too low was more of a problem, or any spikes (eg engine, HF radio etc)? In any...

Thanks for all the replies - I'll now scurry off to look at your suggestions. I'll come back to you but it is a long-term project so could be a few months. Cheers, Andrew

Can you temporarily replace the cable from the base of the mast to the back of the instrument to rule that section of cable out as a cause? (I had a similar problem that was an intermittent cable fault). Andrew

Jonathan - I'm sure you were going to ask, Maxwell Liberty RC1700, 700kg of pull at 19m per minute, with its own Optima AGM up the bow. Sits nicely on the bow of a 34' boat but absolutely no disincentive to pull it all up and try again if you are not happy with holding/lie. (And takes me up...

Vyv, re your post #41 - how about a connection with steel plates with through-bolts in shear? One uses the cross section area of all the bolts (not just one) to calculate shear loadings (on the assumption that the plates yield until the shear force on each bolt has evened out). Sea-bed is a...
