Bristol 32 Electric Conversion Project

Right System for a Hallberg Rassy Rasmus 35?

Hello all.. I'm a longtime lurker in the process of buying an old Hallbery Rassy Rasmus 35. I'm looking for suggestions for the right system for this cruising boat.

Using Leaf or Tesla battery modules for a 48v EV system

Hello, I have just started doing some basic research about converting my 27 foot sailboat to electric. This is not something I plan to do right away, but our current engine is getting old in the tooth and I am interested in switching to electric when it reaches the end of its life, probably in the next 1 to 5 years.It has a 20 hp engine so I am thinking a 10Kw electric would be a good replacement with approximately a 200 amp hour 48 volt battery bank.In researching batteries I came across Tesla…See More

First major test

Following on from my last post, my partner and I were very keen to take a well overdue break from our business. Having just anti-fouled the yacht our destination was a resort island off the coast of far north Queensland. This trip was about 4 hours from our mooring. We knew it was going to be a little rough, but as we hadn't been out for so long we really didn't care too much about the conditions.We cast off at 7:00am and for the first couple of hours made great headway solely under electric…See More

Results after fresh anti-foul

Our yacht is a steel ketch weighing in at 26 ton (imperial). 3 years ago I replaced the 7L diesel with a 70kW electric motor and 235v LiFePo4 (160 Ah) batteries (72 bateries).Since that time my business has consumed most of my time and money. This week we slipped her and gave her a new antifoul paint job. The results were astounding.Coming back from the slip to the mooring (3 nm) she was pulling 5.9 k at about 950 rpm. The hull speed is 8 knots and max rpm is 1300. Drawing 149 amps from the…See More
