(This is the third post in the series, I am planning to build a racy looking, modern solar electric day boat for hull speed cruising in inland waterways.)
I’ve already mentioned the airbed and the cabin light in the previous post.
Most items are essential, others, like the cabin light are fitted to cover a hole or blemish which to restore properly would take a lot of careful time effort and skill. This is not a restoration project and the professional boat builders aren’t going to follow this project.
I probably won’t use navigation lights for my intended daytime cruising on the local lake, but a neat little black cased unit will cover a couple of screw-holes on the foredeck. Maybe they were for navigation lights originally.
Some more serious holes above the dash will be covered by a waterproof bluetooth speaker system, which means that I or any guest can play favourite music direct from their smartphone.Online Xanax Prescription Doctors
More holes on the foredeck will be covered by a horn. I chose this budget black horn with PA mike included. It is very loud. Visiting children will love the extra emergency service wail options and the bright coloured buttons on the mike.
I’ll be replacing the existing sump drain and plug and the grab handle above the dash portside.
A fused switch panel will cover most holes left by the original engine control. Also provides 12v socket and 5v usb’ for smartphones and the Speaker unit.
The original windshield is missing, leaving a neat curved shelf with a lot of ugly screw holes.
I considered a new windshield, quite tricky to get the shape right and curved windshields need special plastic of just the right thickness which won’t scratch easily nor go yellow in sunlight.
But we are only going to be cruising at hull speed with a low powered electric motor, so we don’t need one.
I pulled the rubber door lining strip out of a car my wife had crashed previously and found it was exactly the right length and width to cover the ledge and the holes. I hope it is going to look as if it is a piece of trim, meant to be there- we shall see.
This is not a sea-going boat, nor a child’s inflatable rowboat. It is somewhere in between and the quality of rebuild only needs to be appropriate to it’s intended use, however, two items are essential, a set of lifejackets and a decent bilge pump. My pump has a float switch and manual override.
Anchor, warp and mooring lines are also essential.
I have a set of inflatable seats on order from China, keeping weight and cost down. Also useable on the bank when you moor up.
The battery is an interesting question. In fact, you can take a car battery that no longer has the power to start a car and find that it will work with your motor, just not for very long before it needs a recharge, frequent use will then kill the battery.
I’m using a new purpose built deep discharge battery rated at 120 ampere hours.
The deep discharge batteries have thicker lead plates and will take a lot of use and recharging.
If you can get a large bus or lorry battery that won’t start a bus anymore, that might work OK for a while if you are strapped for cash.
Flexible 100w 12v solar panel and 50 amp controller. I reckon that at low speeds on a sunny day more power will be generated by the sun than used by the motor. As many of you will know, higher speeds use disproportionally higher power, so highest power will flatten the battery without giving a fair return on speed. Simply put the size of your wake, or the ripples your boat makes is the amount of energy you have wasted moving water instead of boat. The whole rationale of this project is that most pleasure is gained cruising silently, gently and slowly while you appreciate the beauty of the water and the countryside around. This fits in perfectly with the need to conserve battery energy. Of course, for many users, the battery will charge up fully during the working week and be used at the weekend.
The motor is designed for fishermen and is an electric outboard with a wireless remote speed and steering controller. Most of these outboards are designed and shaped to bolt onto the bow of a boat and pull it along. But Haswing provide a transom mount version which is what I plan to use. My local supplier tells me his crate from China will arrive by December. Haswing also sell a transom conversion unit so you could buy that and the normal bow mount electric outboard. These are called trolling motors by anglers (Trolling is when you pull a spinning bait slowly on a line behind a boat).
So I hope to use a Haswing 12V Cayman T 55lb – with wireless control when my suppliers crate comes in.
