Radar bracket

[duckmanton]

HI All, l raised the issue regarding buying a small radar, which l have now done, thanks for the responce. l have gone with a Furuno 1623 with the exterior alarm cable fitted at a cost of Aust $2600.
I am now looking at build a pole mount, healable platform for the radome, is it worth it? and ideas as how to do it.
I have a thought on how to do it, but would prefer a tried and tested method and a photo of the contraption would be helpful. Regards Kevin

Hi Kevin
Hope the Arona is getting fixed? As far as this question goes, we have moved our radar to the mast - higher is better in a big sea and clears the clutter from the transom where a pole can be vulnerable. Iris Mary is now in Portugal; the house sold and as soon as all completed I'll be down there too.
Regards
Jeanne

Hi Jeanne, thanks for the manual, presently motor still in bits and may have a later model Kubota to replace with. Glad to here you are crusing again, lucky you. I have the spinnaker pole mounted up the mast, so unable to place radar there, am aware the higher the better, but the pole is the only alterative as having the spinniker pole up the mast is one of the best things l have done for easy of use and stored out of the way. I will be moving the boat over to Tasmania in the next 2-3 months, as have a new job over there. Strong winds and small seas.

Hi Kevin
Yes, we have our pole up the front of the mast as well - but the radar is above it about 28ft up just above the 2nd spreaders. The mast is 43ft. Doesn't seem to get in the way and (as yet!) nothing has fouled it! Good luck in Tasmania.

PBO published some time ago a drawing of the fitting I have on top of the post at the stern of my boat whih allows me to tilt the scanner some 20 degrees either way.Maybe you can find it back. One of the advantages of a pole mounting is that, if your radar goes on the blink, you can easily take the scanner and the display unit to a shop, rather than having the technician come to you boat and climb up the mast (in my case, it was the magnetron that had failed and the fix took 15 minutes...) Another point is that the radar high up on the mast will have more negative effect on the boat's stability curve. At 7 ft above the deck (10 ft above the water), my 1621 has never had any trouble seeing ships but sometimes difficulty in seeing a small buoy in rough seas. You lays down yer money and take yer choices....

A large diameter (4 in) aluminium pole fixed eg to the bottom of a lazarrette and then braced as it comes up though the deck gives plenty rigidity for mine. If you have no lazarette then it will have to be fixed to the hull.

Attraction is that you dont need to brace the pole with cross struts etc since the support as it goes through the deck combined with large diameter does the job.

I have a Furuno mounted in this way (albeit in a 42 ft boat) with the scanner at about 12ft above the waterline. Works fine; the working range is only about 12 miles but wasnt much better mounted on the mast in my old boat (and doesnt get int he way of the sails and doens make toomuch windage etc.).
