Nothing earth shattering but a few more details to make it more interesting. Radar is operational; currently operating on a 1.5v flat battery. Final arrangement will consist of a buck/boost board set at 1.5 v (input 5.5v from BEC) & programmed to a switch on the tx.
Since I hope to use the boat in steering & towing events included details will be minimized & be durable enough to stand up to hard use.

Delete. For some reason can’t upload photos.😠👎

Would love to update but cannot post photos.

Returned home so back at it with THUNDER.

More on the radar installation in the next post.
Turned out to be an interesting experience.

In an RC boat forum in the U.S. there was an extensive discussion about electrical connection methods between removable parts such as deckhouses and/or the roofs of deckhouses that have operating radars, navigation lights, etc.

Since I use rare earth magnets to secure removable deckhouses and roofs I particularly liked the suggestion of using those magnets as the contacts. Sounds great; one component serving both as a hold down force & an electrical contact. Yet I vaguely recalled from one of my numerous physics or metallurgy classes that magnets & heat don’t play nice together. Undaunted I proceeded anyway. Using what I thought to be minimal heat to solder the wires to the magnets caused about 85% of their magnetism to be lost. So four additional magnets had to be installed to hold the wheelhouse roof in place. Fortunately I had enough magnets & space to do so.

Photo 1 Wires from 1.5v output side of buck/boost circuit board soldered to outboard hardly magnetic magnets. Input voltage supplied by rx. Board can be seen on side of wheelhouse. Inboard magnets hold roof in place.

Photo 2 Radar leads soldered to outboard magnets. Inboard magnets provide holding force to keep roof secured.

Note to self; don’t make wire connections to magnets. You can’t fool physics!😊

trim around house.
Photo 3 Anchor not yet secured.
Photo 4 Mast & light scheme completed.

Lights non-operational since I never run at nightfall. Things yet to do include graphics, a couple of ventilation stacks, & non-skid strips on the deck where there is no bulwark. Then it’s a finished build.

I always look forward to this sail. It’s about the only event my club holds that I can attend. My fault not my club’s.

Thank you Ronald. Information about tug lighting is always useful they are so complicated dependent on tug’s length, length of towing hawser, etc. Nav lights on all boats must be displayed beginning at dusk so it makes total sense that the same applies to towing lights. Day shapes are another complexity.
Then there are lights for other burdened vessels such as fishing draggers, or vessels unable to respond to the helm.
Lights & day shapes are indeed a challenge for those sitting for their maritime licenses.
The tug in the photos is very interesting. Do you have any more photos or info about it?

Graphics applied so finito. Again, many thanks to VLB for information they supplied & permission to use their logo.
