The owners have sailed it from the Pacific Northwest to New Zealand and back, plus two round trip circumnavigations of Moresby Island in the Queen Charlottes Haida Gwaii combined with three full circumnavigations of Vancouver Island.
Thistle is equipped for offshore with self-steering gear, solar panel, and an intermediate stay with runners, among a full complement of cruising gear. The boat spent its early life in Maine. When the current owners bought it in , they shipped it to the Valiant factory in Texas, where builder and Valiant Yachts owner Rich Worstell oversaw a refit, bringing it up to the current standards.
It was then shipped to the Pacific Northwest. The quality interior joinery provides a warm and comfortable feel. Lockers and floorboards are all securely fastened for comfort at sea. The hull sides throughout the boat are lined with teak. Shelves are to port and starboard with removable rails. There is a locker with shelves to starboard and a hanging locker just aft of it.
To port there are four drawers, providing plenty of storage for personal gear. Moving aft to port, the head has a separate shower stall with a seat, rare for a boat of this size and vintage. In my experience the issue will be with the aerial. Buy a Raystar GPS. Dispose with the old Raynav GPS aerial.
Go through the Raynav menus and set it to be a repeater. You can then use the Raystar output for other instruments as well. Joined 11 Jun Messages I know it's an old thread but I've just been through the same process - RN very slow to get a fix, takes ages to build up signals from a decent number of satellites, and randomly loses fix and needs restarting from time to time. Doddle to install, given that the original boat wiring had a bit of choc block with the RN NMEA connections brought out to it.
I'll leave the old Raymarine antenna installed on the aft deck as it is the easiest way to fill the hole the cable goes through! From where did you buy the SirfStar? Joined 16 May Messages 42, Aerial is a likely candidate, as is any internal battery. Also the self calibration of the carrier frequency can go out in old units, particularly if they are left switched off a lot or the internal battery is flat.
Leaving it powered up for several days can help with some units. It may self calibrate over time. Not sure if this applies to the Raymarine ones. I improved an old GPS by tweaking the crystal to the frequency the receiver was expecting, but I was in a lab with a Rubidium reference and no work to do at the time. You could get a ublox receiver module for 20 or 30 quid and stick it in the old box.
Aerial connection is certainly a possibility, although the fact that not touching the cable and just restarting the GPS fixes the problem suggests that it is not that probable. And the reported signal strength is well up - it's just that the RN doesn't seem to be able to get a position from the received signals.
The Alarms Set Up list is displayed, showing the current settings as shown in Figure Page Cursor Echo Chapter 3: Operation 3. The options available depend upon the current operating mode; It also shows the factory default setting and provides a space to make a note of the new default setting.
The current units are shown for the heading value in the status bar. Cursor Readout This option controls whether the cursor data is shown in latitude and longitude or in range and bearing. Alternatively, you can show both types of readout, in separate boxes, or turn the cursor data box off. When set to ON, if the status and locked heading of the autopilot changes, they are displayed in a pop up box.
The box is removed from the display after two seconds. This option allows you to specifiy the source of the GPS data. The following table lists the Plotter Set up parameters and their options, shows the factory default setting and provides a space for you to make a note of your new default setting. This is the default mode and is the only mode available if there is no heading data. Note: When the datum reference grid is changed, the geographical position of waypoints remains constant.
It also provides the ability to set up a Coastal GPS by manually retuning it to a different differential beacon. SNR provides a measure of the quality of the received signal and is dependent upon signal strength.
Page Chapter 5: Installation This chapter provides instructions to assist in planning the installation of the Raynav GPS Plotter aboard your vessel. Note: If you wish to practice using the Raynav GPS Plotter before installation, you can connect it, via a 1A quick blow fuse, to a 12VDC power supply and operate it using the simulator mode, as described in Chapter 2: Getting Started. Page 96 Figure Typical Suppression Ferrites Connections to Other Equipment If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be attached to the cable near to the Raymarine unit.
Retain the carton and packing materials in the event that you need to return the unit for service: System Parts and Accessories Item Part No. Ideally, the unit should be mounted horizontally in a location that is open and clear of any masts or other structures that could block line-of-sight reception of signals.
Page 99 Chapter 5: Installation mounting surface, remove the two plastic tabs 1 obstructing the cable channel. Note: Failure to remove the plastic tabs from within the cable channel could result in cable damage. Screw the supplied brass studs 2 into the underside of the GPS Antenna. Screw the pole mount base to a suitable pole or rail mount bracket, having an industry standard 1inch 14TPI thread, until secure. Pass the cable through the centre hole of the pole mount base A or insert the cable into the side exit channel B.
Page Plotter Installation Chapter 5: Installation 5. Page Trunnion Yoke Mounting 51 mm 6. Note: The gasket should be fitted to the rear of the unit to ensure EMC compliance.
Page Panel Mounting Make sure that there is sufficient rear access for mounting and cabling. The unit can be panel mounted, using the panel-mounting kit accessory available from your local Raymarine dealer.
Screw the studs into the vacant holes at the rear of the unit, hand tight only. Slide a spacer ferrule onto each stud. Secure the unit with the thumb nuts, hand tight only. Page Cable Running Chapter 5: Installation 5. Additional cables will be required if you are connecting to other equipment. Page Antenna Connector 5.
Ensure that the protective boot covers the connector. Note: If the supplied cable is too short, use an extension cable Part E , or consult your Raymarine dealer. It is recommended that only a single extension cable is used as each extra connector will reduce signal levels. Page Chapter 5: Installation If a longer power cable run is required, use the supplied power cable to connect to the unit, then use a suitable connector block to connect the free end to the extension cable.
The supplied power cable has a cross-section of 2. The data is passed from instrument to instrument via the daisy chained cable. If necessary, adjust the lighting and contrast see Chapter 2. If required, change the default language settings as follows: i. They will ensure that service procedures and replacement parts used will not affect performance.
There are no user serviceable parts in this Raymarine product.
