electric propulsion

Hi everyone, We're interested in showcasing what our range of Mitek electric motors and batteries can do here in the UK and are looking for a nice looking boat for this. My preference is for a small, classic Italian Lake looking boat. I've come across designs from Glen-L Marine...

Hello! I am part of a small startup who have been recently been approved by the U.S. DOE to develop a 7M RIB. We already have a preliminary design and multiple partners (university, material science technology, propulsion design). However, we are moving into a detailed design phase and have a...

I'm in the process of changing our electric drive system from lead acid/brushed dc motor to a lithium battery and BLDC liquid cooled motor. Unfortunately slightly against the clock and while living aboard in lockdown with a couple of small kids, but hey ho... Anyway, I'm looking for solutions...

My boat project is a 11 ft L x 48"W planing hull micro-skiff, it is a Carbon fiber/Basalt fiber skinned foam blank. I have decided to build an electric surface drive I will be using a Maytech, MTI 120116 brush-less motor that puts out 18.8 KW max or about 25hp. I am building a motor and shaft...

Hello. I apparently joined this forum some time ago, then forgot. Boat design has been on my mind a lot lately, though, and so I started reading here. Then I wanted to comment, and... well, here I am. My wife and I would very much like to own a cruiser in the 34-40 foot range (11-13m), and...

Hi, like many people I am looking for a cost effective electric drive for a lightweight tender to get me 200m to and from my swinging mooring. Speed is not important but must be able to cope with 4 or so knots of tide. I have been looking at various threads and I wonder if this might work...

Good Evening. I am having problem deciding the specifications of my propeller, I have already obtained the curves for Resistance and Power vs speed. My ship has a Length of 91m, beam of 10.5m and a Draught of 4.5m. It is presently run using a 5 bladed 2.8m dia two in number propeller and with a...

Dieter Loibner has an article in the April/May issue of Professional BoatBuilder magazine (proboat.com) about Piotr Zin, founder of nascent Zin Boats of Seattle, and the ZR2, a new 20‘ (6.1m) carbon runabout with a 360V Torqeedo Deep Blue 50i 1800 propulsion system. "...the ZR2 is for an...

I am a University Student studying Naval engineering working on an electric driven high performance planing racing powerboat (8m in length). I am trying to find a suitable propeller design for this craft. From modelling resistance I am looking to achieve 4kN if thrust with an input engine power...

I have a 50' x 13'5'' steel houseboat/barge. We are year round liveaboard and cruising (on pure solar electricity) for 8 month of the year. Canals and rivers in the UK. I'm considering what upgrades we can carry out to get a bit more speed out of the boat. The current drivetrain is a Lynch...

Hi everybody, glad to be a new member of this great community. I have a pet project in my mind which is creating a "race" style boat with electric propulsion. (I am totally aware of the cost of electric motor and battery systems.) I'm trying to find a hull design for the following: I was...

What would be the average energy consumption, range and running hours with different speeds (slow, cruising and max)? What would be a right size diesel generator for backup/hybrid system? How much regeneration could folding propellers produce? How much solar would need to be installed to run all...

I manufacture electric outboards. I have read several places on this forum suspicions that electric outboard motor manufacturers claim that electric Hp are larger than gasoline Hp. Not so. A Hp is a Hp and a Watt is a Watt. That said, I claim that our motor is approximately equivalent to...
