Re: Too many VHF aerials?
Yes it can be an issue
See : https://www.seamagazine.com/importance-antenna-placement/ We use a splitter on our main mast VHF antenna for Ais and Fixed mount VHF. It works very well...and better IMO than having a proliferation of antennae Cheers Alan Elyse SM437

Re: Sidepower SP 155 TCi needed

Sharing is caring, so here are the wiring diagrams and schematics for the A54 bow thruster that I got from Amel.
I also added the instructions to replace the sacrificial flexible coupling, which I have had to do. Hope this helps someone. -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com

Re: Too many VHF aerials?
Scott SV Tengah
I just replaced my main mast VHF antenna and traced all the other ones. On our A54 main mast, there are two Banten aerials, one for the VHF and the other for the FM/AM radio.
On the mizzen, we have the AIS antenna, connected to our Furuno FA-50. As you may know, AIS transmits on VHF frequencies. The second antenna on the mizzen is the weather fax, which I don't really use. Based on my understanding, it's important that the VHF and AIS antennas are at least half a wavelength (a meter) apart horizontally and ideally on a different vertical plane. That's how Amel installed it on my A54. So if you're going to add an AIS antenna, put it on the mizzen, which it seems you're planning on doing. Having VHF and AIS on the same mast will negatively impact both. That said, in reality, Class B AIS doesn't transmit that often and we don't blabber that much on VHF that I'd be too worried about that affecting AIS that often. :) -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com

Re: Too many VHF aerials?
Why do you say too many? Are they interfering with each other. We have two on te main mast and one on the mizzen; AIS, VHF and WeatherFax. They seem to get along. In my marina the is currently a motorboat with 11 of these white sticks, make me wonder what they are for. But it also has 4 domes and 2 Radars. The owner must be very important :-)

Re: Batteries
Danny and Yvonne SIMMS
We bought a set of deep cycle lead acid batteries from West Marine in Newport Rhode Island in 2009, got 8 years out of them. They would have lasted longer if I hadn't messed up by leaving the freezer open and switched on when I left the boat on its mooring for 6 weeks. I leave two fridges on to use the power from wind gen and solar but hit the wrong breaker. They were labelled "West Marine". I replaced them with Trojans in New Zealand Regards Danny SM 299 Ocean Pearl

Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
Although not fitted with a Volvo or a 54, Cream puff is fitted with a Vetus Waterlock muffler. Even if you do not have the Vetus model, the setup for the water-lock is probably very similar. The muffler is fitted with a drain screw. Undoing this screw while underway would absolutely eliminated any chance of water back-flowing into the engine. If you opt to do this, it might be advisable to attach a hose pointed toward the bilge. And, of course, do not run the engine with the water-lock drain open.
So, for those of you not wanting to run the engine at all while underway on long passages, this is an alternate option.
With best regards,

Re: Too many VHF aerials?
Ryan Meador
Hi Mark, Do you have a Class A VHF? Those are the type that use two antennas for DSC, but I've never seen one in the flesh -- most recreational boats use Class D, with a shared antenna. On our boat, we have one antenna on each mast. The main mast is split between the nav station VHF and AIS, and the mizzen is connected to the helm VHF. Both VHFs have DSC. This setup has worked well for us. If the splitter fails, it's easy to connect the nav station VHF directly to the radio, and I believe we also have a jumper between the helm and nav station so we can swap the antennas to either radio by plugging a few wires (that's what the wire is labeled as by the previous owner... I haven't tried). And we also have a handheld as a third backup. I think having the AIS on the main mast for better range outweighs any drawbacks of having a splitter.

Too many VHF aerials?
marklesparkle59
On my main mast there is the main VHF Radio aerial, on the mizzen are the DSC aerial and the Emergency VHF aerial and I would like to add an AIS aerial to avoid a splitter. I am considering replacing the Emergency aerial with the AIS and using a bolt on emergency. How have other owners coped with or avoided this proliferation?

Re: Too many VHF aerials?

Hi Mark, The main mast antenna is hooked up to our VHF analog radio. That radio also has a button for DSC (the D standing for digital), but I always assumed that the DSC signal was transmitted via the same antenna as the analog VHF signal, not on a separate antenna. At least, when I installed the radio, there was only one antenna output terminal on the radio, so I don’t see how it would use two antennas. Our mizzen antenna hooks up directly to the AIS transceiver, no other devices use it. If the either VHF antenna failed, we also have a spare antenna on board that could be partially hoisted for elevation. Tom Peacock SM 240 Aletes Martinique

Re: Batteries
Is this Dr. James Cromie? Kim and I were just talking about you and wondered if you and your lovely family ever made it down. We hope you are doing well and your parents are at peace with your sailing adventures 😉. Hope to cross paths and catch up. We are heading back to St.Martin by early February then a leisurely pace south to Trinidad by end of season. Happy new year! All the best, Chuck and Kim

Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
Scott SV Tengah
Fantastic information from Olivier. Thank you. I presume the flap is a specific Amel part or can we buy it elsewhere? I am totally for supporting Amel but the shipping costs from France get a bit high for a small part. :)
On another note, what is the general guideline for using the Volvo D3-110 and the Onan when the boat is heeled over? I do recall reading the Onan spec that it shouldn't be used at more than 10 degrees constant with short bursts to 20degrees. I can definitely hear a change in genset note when the boat is rolling and it is not related to the exhaust outlet going underwater. Back in my car racing days, I was very aware of oil starvation when the oil sloshes to the side of the oil sump while cornering. The solution there was either baffles (helps) or a dry sump. Is this a concern with our marine engines/genset? -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com

Re: Batteries
James Cromie
Hi Chuck - I purchased a full set of Trojan 31XHS and a DEKA 1231 starter battery from DCBattery “dot” com. They provided excellent service and shipped them all to Aruba for only $230. The trojans were $205 each, and the DEKA was $135. I thought it was a good deal to get the exact batteries I wanted. Shipping to PR and any taxes should be even easier. All batteries arrived in good condition based upon personally load testing them and manufacture dates were the same month as delivery to me. contact was Danny Rojas: danny “at” dcbatter “dot” com Best, James
