Re: Navigation lights location (R/G, Castle)

I've settled on the "flat pancake" style horizontal surface mounted combined port/starboard light to be mounted on a flat plate to be welded into the front of the pulpit: https://www.whitworths.com.au/media/catalog/product/cache/1/small_image/400x400/9df78eab33525d08d6e5fb8d27136e95/5/4/54145_rwb451...

For completeness; I've found another way to mount nav lights; a combined R&G light on a removeable pole: https://bla.com.au/wp-content/uploads/2020/04/121302.jpg Supplier is here: https://bla.com.au/product/attwood-lightarmor-removable-navigation-lights/ ebay too: https://www.ebay.com.au/itm/1632417...

Re: Navigation lights location (R/G, Castle)

Ahh the problem with a mast head tricolour is that when motoring the white all round light is required to be at least one metre above the red and green side lights. Also, my boat is set up so I can launch it with the mast tied down and motor for the occasional river trip etc. Nothing needed for moto...

Re: Navigation lights location (R/G, Castle)

I could mount a small horizontal plate just above the base of the pulpit for the first, flat type, but between the furler, the anchor, the forestay, that's a pretty busy bit of real estate in there and I am loath to complicate it further. I could mount the same type on a raised surface on the anchor...

Navigation lights location (R/G, Castle)

Having just installed a new stern light (which isn't working yet, GRRR, ran out of daylight for chasing that up), I discovered my starboard (G) nav light isn't working, probably because someone has crushed it against a jetty. At least that's how it looks... Bloody jetty drivers. So, finally I'm goin...

Re: Spotted. TS's for sale on the net.

Aluminium, unlike steel or stainless steel, has no fatigue limit. You can stress steel (including stainless) to about half its ultimate tensile stress an indefinite number of cycles without suffering fatigue failures. With aluminium, less stress allows more cycles, but there is NO level of stress at...

Re: Welding aluminium question

Your strip of "pure aluminium" will also be some sort of alloy, not pure. For example, on the Capral website , the vast majority of extrusions are 6060 T5. So the $64 question is whether the two parts of potentially different alloys present a problem. If it were my rudder, I'd be happy to go ahead, ...

Re: The Future Of Trailer Sailing

With petrol or diesel, if you want more power, you need a bigger motor. A bigger motor weighs a lot more, which costs fuel. A bigger motor costs more to build (unless it's just the same motor with bigger holes!) A bigger motor (particularly petrol) is much less efficient when run at a small fraction...

Re: How do you locate leaks in a fibre glass hull?

I used to have an RL24 that developed a leak. I tried drastic ways to find it such as filling it up with water and tilting the trailer. Then once, after months of bailing it out and using a syringe into the under floor cavity, I noticed a slight trickle of water coming from where a trailer roller w...

For cockpit drains my Ultimate 18 had PVC pipes between the transom and the cockpit just siliconed in. I replaced with skin fittings and hose. Silicon rather than rigid epoxy/polyester resin would be a step forward but even the silicon has limited flexibility. There's not enough room in a Castle fo...

Here is a photo from Cruisers forum of the sort of thing I have in mind. Any ideas where I'd find one (or get one built). Ideally 400mm long, 300mm wide (deep as built), 250mm high (as mounted), with the open side 400 x 250, but hey, if someone's already making something close... Fibreglass tanks.jpg

Re: How do you locate leaks in a fibre glass hull?

Clearly any breach of the surface of the hull is suspect and sometimes the problem is not visible even when you're staring at it. When you're struggling to find the leak, it's got to be somewhere the gelcoat has been breached; a fitting, a screw hole, a through hull, a join with a crack, (a removab...

Re: Battery layout with vsr

Which battery do you want to be last to go flat?
Ordinarily a VSR (voltage sensing relay) is used to make sure the starting battery in a 4wd or inboard boat is charged before the house battery gets any power.
