Electric Inboard Motor

Hi all - any sailing liveaboards have experience with an electric inboard motor? Is it easy to convert your current vessel to electric or buy an engineless yacht for a deal and install one on your own? Can you go cruising with electric or are their limitations if you don't have a hydrogenerator? I'm new to this but trying to learn as much as I can with the goal of owning a completely green boat. Any thoughts/feedback welcome! I'd love to hear it all.

Belt drive motors -- inboard or outboard? Why?

My Verreal RS has its motors mounted behind the rear truck but I've seen other boards where the motors are forward of the trucks, between the two trucks.

Why would a manufacturer choose one position or the other? Is it just about clearing the battery/ESC enclosure? Or is there some other consideration?

The inboard M1 killer hub motor board

For those who don't know, I had 2 belt drive boards. Just yesterday I sold one of them because they were so similar. I have a raptor and an LHB board and wanted to sell one, since no one was giving me my asking price for raptor I ended up selling the LHB to fund my next LHB custom build. Sad to see one of my favorite boards go, but I know better things are coming. Here is the next monster...and it's all about being lighter than my first LHB and believe it or not, faster. It's the perfect complement to a belt drive board I think.

-Custom shaped deck with black/green theme, will accept 90mm and 97mm flywheels. Will have built in wire channels as all his boards do for a clean look. This is why it's just easier to have him build it rather than trying to do it yourself on a board w/o these wire channels. I'm only 140 lbs, so this time instead of 9 ply I'll likely go with a 8 ply board to cut down on weight. The 9 ply is overkill for my weight.

-Dual VESCs with heat sinks

-97mm ABEC all original flywheels so non smooth roads won't be an issue, and will give more top end

-Dual Carvon 116 kv motors, V3 to be released soon Easy to swap wheels! See here. https://www.youtube.com/watch?v=KulZ-LcXq2A

-12s4p custom pack with BMS

-Remote/receiver to be determined (either steez or GT2B with modified enclosure)

-Theoretical Top speed of 57 miles/hour (92 km/hr), real world top speed with my weight expected to be around 47-50 mph (~75-80 km/h). Speeds determined by esk8 calculators online, I've found these to be accurate. They were on the dot for my last LHB board and the raptor.

As always I will be posting videos with GPS overlay to prove all these numbers. I don't think anyone came even close to my LHB scarlet top speeds except one person, but he had a DIY build rather than a complete one with warranty. This next one will set the bar for top speed even higher. Right now everything is pending motor availability, which is about 3-4 weeks out. I guess my title of comparing it to inboard M1 is not even fair.

Keep an eye out on my youtube channel for an unboxing video and more videos when I get it!

Inboard to Outboard motor pod?

Gday all, novice to the boatbuilding and thought seek some more expertise opinion on couple of issues.

I found a excellent condition 18foot fishing boat hull that had a outboard on the back that was overrated according to manufacturers build plate rating. Plate says 140, motor is 175. Motor wasn't hooked up and when dug a little deeper had never actually been run on the hull, only placed on back to get more cash from the sale..lol

Not a huge problem, will throw a smaller motor on the fishing boat hull as time allows.

My question is: This 175Hp I have now sitting in shed is taking up space and they don't seem to hold re-sale value well as a stand alone item without a boat to go with them.. I am contemplating purchasing a cheap 19 foot ski boat hull have found (with no motor, for $1000) and throwing the 175HP on that and maybe seeing if can then move the ski boat hull/175 outboard together for a any/small profit if can potentially?

The ski boat I am looking at, is a bare hull (19foot) in fantastic condition, (never been fitted out with seats/inboard) but would require a 'pod' to convert to outboard? I am just a novice so not really sure how much cash/work/time this could entail maybe?

Opinions? or Expertise advice be appreciated..lol

Inboard motor died, support not responsive

I decided to ride around in damp conditions on tuesday (but really tried to keep the cover area dry, only some damp footprints near it). Stopped to swap the battery, but the board wouldn't come back on. Took the train home like a peasant, put the board on the radiator, and it turned on fine an hour later. It rode well the next day for about 15 miles, but then suddenly got wobbly when brakingβ€”one of the motors died.

So the messed up thing is that I emailed support@inboardtechnology.com on tuesday night about the board death, got the automatic reply with a promise of 24hr response time, then emailed them a video of the dead motor on wednesday, and STILL haven't heard back.

Is having the motors in the wheels like Inboard a better design?

With the speculation of the new board, we have to ask ourselves, is the motor in the wheels a better design?

It would make sense that fewer moving parts = a more reliable design.

Inboard boat motor question:

Hello everyone: I'm about to buy a small project boat with I/O engine in it. Owner said the starter went bad on it but ran great before that. Boat sat for about a year sense and he had removed the starter.

My question is how can I test to make sure the motor is not locked up with out power. Can I just put it in gear and see if I can spin the prop? Or is there a better/different way to relatively simply test it? Thanks!

Motor in question is an inboard Mercruiser 350 Magnum

First boat advice.

I've started looking for my first boat and have been offered a very cheap boat, about 2k, a maxi 77. Whilst the rigging, hull, keel bolts and sails are all in fairly good condition, the engine has been removed and replaced with an outboard and the inside would probably need redoing. It's very basic but functional. I can afford a boat up to about 10k but I'm wondering if it's better to start with something functional as I learn how to maintain the boat or to go for something that might need less work but cost more. Any thoughts?

[SECRET] Uí Ímair-class Aircraft Carrier

#Uí Ímair-class Aircraft Carrier

The Confederation of Irish-Nordic-Cypriots’ mandate within the Global Interoperable Guarantee for Allied Support (GIGAS) has shifted the calculus of STOICS Allied Maritime Command’s doctrine into a greater expeditionary stance. In order to better fulfill its expanded defensive responsibilities and support allied operations further afield, particularly in regards to GIGAS commitments to Japan, Siberica, and Canada, the Republican Navy and Royal Commonwealth Naval Army have collectively commissioned the development and construction of four modern supercarriers that will serve as a visible demonstration of the INC’s new status as a revived global force.

Named in honor of the Norse-Gael Dynasty of Ivar, the four vessels of the UΓ­ Ímair line of warships will undergo construction by the Aircraft Carrier Alliance and Maersk’s Odense Steel Shipyard, with the lead vessels of the class, the RCNA Ivar the Boneless and RN BΓ‘rid mac Ímair constructed, launched, and commissioned in eight years. The remaining two vessels, the RN Sichfrith mac Ímair and RN Sitriuc mac Ímair, will undergo a more rapid five year construction and commissioning cycle.

Given existing RN interest in stealth carrier designs, the UΓ­ Ímair-class is based on a novel hullform inspired by the former USN’s CVX 3C Stealth Monohull, Study S2 as designed by J. David McWhite, to meet the most stringent signature requirements in Radar Cross Section, infrared, and noise. The vessel inherits a myriad of conventional and quantum radar, IR, and hydroacoustic stealth technologies derived from the Visby, Gustavus Adolphus Magnus, and Viking classes, while incorporating a [Mignolecule](https://www.reddit.com/r/w

Charging my batteries

I’ve got a 37’ Prout catamaran with 4 x 100 watt solar panels, 3x gel pack group 42 batteries and a 12v starter marine battery for the engine. The engine is a 30hp beta marine inboard and I’m not sure what capacity the alternator is.

We left the dock about 2 weeks ago and I’ve been doing more and more sailing and less motoring, and I’m running in to problems charging the batteries. At anchor if there is room i can stern anchor as well so I get sun on all the panels, (depending on tides and current of course, comfort is important) but when I’m underway using a lot of juice (nav, radar, auto pilot) the sails are always covering at least 2 of the 4 solar panels - if not all 4.

I’ve been running the engine a bit here and there to supplement, but I don’t know much about this. Like I said- I don’t know the capacity of my alternator, but assuming it’s standard-ish for a 30hp diesel- do you have any tips?

Like, should I let it idle, or rev it up a bit? Should I do it while I have load on the batteries or when there is as little as possible? Can the batteries accept all of the power from the alternator or should I run it for a half hour here, half hour there?

Should i get the engine temp up via revs so it’s more efficient?

Any tips are appreciated!

Chapter 3

Standing awkwardly on the other side of the interior airlock, Specialist Rowan Taylor struggled to find any meaningful layout of the craft they found themself aboard. Several stressful moments stretched past them as they found every attempt to request information from the Holy Mother’s Directive’s summarily denied. Finally throwing their hands up in frustration, Rowan muttered obscenities towards gods and men. Shouldering their duffel before scooping up a hardcase container, they ambled awkwardly down the sole passageway available to them.

Meandering slowly through the passageway, it occurred to Specialist Taylor that maybe the onboard VI, if it was in fact a VI, would be able to help. β€œUh, computer? I need to report to the commanding officer on duty. Any, uhm, assistance, would be highly appreciated.”

With a soft tone chiming directly overhead, a disembodied voice spoke. [Specialist Rowan Taylor, you are to report to Medical at your earliest convenience. Debrief will occur after you have been given a full physical and had your possessions stowed in your crew quarters. Do you require running lights to illuminate your way?]

β€œUh, yeah, that’d be great. Thanks, magic voice lady.” Chuckling quietly like they’d told the universe’s greatest joke, Specialist Taylor made their way confidently now down the passageway, following the soft glow of blue lights embedded in the deck plating.

After softly knocking, Rowan sagged against the bulkhead opposite of the door labeled Medical. Several moments passed, before the door glided open, revealing a squat, half-meter creature garbed in a white smock, seemingly glaring up at Specialist Taylor under the thickest eyebrows this side of the galaxy.

β€œAh, but you’d be our newest arrival, hm? Can’t have you lollygagging in the passageway, now can we, hm? Come in, come in, let’s get your physical out of the way so we can get you checked into your crew quarters, hm?”

Albin Vega Mk3 - Stern Hung Rudder vs Outboard

I have an Albin Vega Mk3, and as many will know, this boat is a nightmare in smaller marinas, especially if there’s a bit of wind. This is mainly due to the position of the rudder, which is behind and above the propeller. To that end, there is no wash from the prop over the rudder, and so to turn, you need to get some speed up and get water moving over the rudder, which is easier said than done in small spaces. There’s a bit of help with prop walk, which kicks the stern to port, however, add in a bit of wind from an unfavorable direction, and turning the boat becomes almost impossible, though I’m sure that some experts may find this a walk in the park, I don’t. In addition to this, I really miss the ability to spring on and off a pontoon, using a bit of prop wash to keep the stern held tight against the pontoon, or instead to send it away from the pontoon.

So my plan is to either have a transom hung rudder crafted, and to install this and remove the keel hung rudder. Alternatively, I may install an outboard bracket, and install a small outboard that I would make use of in marinas when required. The outboard option might come in handy at some point as an auxiliary engine too.

I’m after your thoughts on these options. Maybe you have a similar situation that you have dealt with, or maybe some more experienced boat owners would have insight into this scenario and be able to offer an opinion. Would love to hear any thoughts, concerns, alternative etc.

Update: 21/11/21 I fitted an outboard bracket, and a 58lbs trolling motor. I can turn this boat on the spot now, even against a strong breeze. I can also use this to actually steer the boat very effectively astern. I have also been able to very effectively use the main to move me astern, and use the new motor as a bit of a thruster every time I start to go off course. I can also use this to power the boat if required, and use it for the tender. Thanks to everybody for their help with this.
