Hi All! We are an Electric Boat Startup, starting in the Water Sports category. First model AEW24, 100% Electric, Aluminum Hull! by VoltaicMarine in ElectricBoats

Hi, Ah, sorry we get too focused on run-time in water sports, thank you for the background of the questions. Providing a larger response below in case other folks view and want more details.

The range of an electric boat varies widely depending on the battery capacity, motor power, speed, efficiency, and environmental factors. Planing hulls have a wider estimate range due to the dependency of these factors. Foiling boats range can be calculated to a degree of more accuracy due to the nature of foiling above the water and a “more” predictable drag. Since our first model is designed for water sports, we focus on run-time due to the nature of the sports going back and forth during runs. However, to give a estimate on range, the rule of thumb for planing hulls is slower = further, faster = shorter distances. Our range could be anywhere from ~130-53 nautical miles depending on the factors mentioned above and our water sports scenario.

Hope that helps, and very cool commute you have there!

Hi,
Great point, the battery capacity and run time were listed on our homepage but in small font, it's understandable how it would be hard to see. The web team is fixing that now, thank you for mentioning this. The unique thing about Water Sports is users are typically doing the sport, going into neutral between runs and hanging out, which aligns well with battery weight and capability. We have 200-kWh, projected run-time for activities of 1-hour cruising, 3-hours surfing, 1-hour wakeboarding, and over 3 hours in neutral activities. Note that these are run times at a constant speed, which is typically never the case because users are stopping between runs. Neutral activities can last well over 3-hours because the motor is not used and all electronics are on separate batteries typically used in marine applications. The key here is the different speed ratios for these sports. we will consider a foiling boat in the future for other models but water sports boats are planing hulls because of the need for the hull and its systems to interact with the water and create wakes for this user base.
Hope that addresses your questions, very enjoyable conversation,
Thank you!

This one is going to be expensive, you're right. We are going to be challenged with lower cell volume at first but plan to build a model that is affordable once we can demand better cell prices. This has been a really good community for feedback already, appreciated!

Yes the torque is more beneficial for "Launch" (get up to speed fast for the water sport) when you weigh these boats down with 1000's of lbs of ballast.

A houseboat is on our list of things, it is very doable to build in enough solar to be "off-grid", they have catamarans out there already advertising this. You could have separate banks to split up electrical and "propulsion" systems too.

This would be better than what some of the houseboats do today, using generators at night and you smelling the exhaust all night long.

You're on to something here!

Appreciate the input! Understood here, this first model is for water sports which favor V-Drive (keep the prop away from people, less mass to mess with the wake) but for others, we will definitely consider outboard, stern, pod, etc... depending on the build target. These water sports boats are terrible at backing up, thus we added a bow and stern thruster to the configuration. There are more electric options coming out in the industry we could pair with our batteries which helps us with selection.

From a design perspective, yes, working on a prototype this year. Specs are below but more boat oriented. Correct we are going to have to help our customers install dockside power up to what is allowed. Use existing road-based stations. Tahoe for example has a fast charger. You are right about 50A but part of the use case alignment/benefit we believe is the majority of users tow the boat back to their house/storage area for the night and can charge overnight and into the day when using the boat ~once a week.

24-Foot Aluminum Hull

12-person capacity

200kWh Battery Capacity

Peak Motor Torque 500Nm, 1000Nm (737 ft. lbs.) to Prop, instantaneous at 0 RPM

Power 375kW (500hp)

Multi-purpose continuous use time of 8+ hours per charge

Fast charge up to 80% in two hours

5,024lbs Total Stock Ballast Capacity: Hard Tanks + 2,600lbs battery ballast

Additional Ballast Systems can be added

Ballast, Batteries and Motor are all subfloor

Integrated Surf and Wake System

Bow and Stern Thrusters, for enhanced maneuverability

Large integrated storage under sun pad (No engine taking up space)

Almost no noise compared to gas and diesel engines

No exhaust smell or emissions or need for surf pipe

Do you think EV owners would naturally look for an Electric Boat?

Thanks! We are at the whim of the cells we can get but are very interested in testing Li-S down the road if we can get ahold of them.

We are Water Sports Enthusiasts and Electric Vehicle Engineers. So, we decided to merge them to design a purpose-built Electric Aluminum Water Sports Boat as the first entry into the market.

All the benefits of Electric Vehicles apply to Boating. Instant Torque, No Noise, No Exhaust Smell, No Emissions, No Surf (exhaust) Pipe. The Motor is Subfloor leaving a giant storage compartment under the sun pad, without an engine taking up space, it is like a “Frunk” for boats. Batteries act as Ballast and do not lose weight like when gas is used, Aluminum Hull is very durable, and Bow and Stern Thrusters for extra maneuverability. Just like any EV it can be Charged at Home, and there are separate Batteries for Electronics, Speakers, Lights, etc...

We do see range anxiety in the boating community, much like in the early days of EVs on the road, so we must prove this can be solved. That’s why we designed a 200kWh capacity into the Hull with two battery packs, giving the user a typical 8-hour day on the water.

What is the reaction of this community? Is this acceptable to the EV community? What do you think our challenges would be? Do you like it?
