Re: [Electric Boats] Daydreaming about the next project: An electric day cruiser...

 



Hey John, Dan Here.  I have had the same dreams all the time.  Then I started building my own boats.  I now build for others too.  As you may or may not know, ANYTHING can be "electrofied".  I start with one of the many designs at Glen-L.com, then look at the plethora of E-O/B conversions or better yet, do an inboard and call folks like Jim Lambden @ Electro Prop for motor and battery solutions.
 
Hope you turn your dream into a reality.  That is part of what this forum is all about.
Dan H.

Subject: [Electric Boats] Daydreaming about the next project: An electric day cruiser...

 

So I was starting to daydream about what the ultimate daytime cruiser would be like....

A classic wooden launch would be really cool, with a nice bimini for sun protection.

The Duffy is really cool. And something like that could have some wood worked into it...

The thing is, though, that the one thing that seemed limiting about the sailboats I loved was how slow they were.  We all know how much more exponential power it takes to push a sailboat type hull (basically including a launch or a Duffy) past hull speed.

What's the top speed of a Duffy???  Maybe 5-6mph max cruising speed?

I'd really love something that could cruise at 8-10mph.  But to get a classic monohull to do that, I'd have to spend a BOATLOAD of money on a battery approaching something that could be used in a Tesla.

What about a pontoon boat?

It's not as classic, but it would at least let me go fast enough to get a reasonable distance from the marina.  And a catamaran form would be MUCH more efficient than a monohull, with plenty of space for passengers in a small, light form factor...

If I built something like a 6' by 12 or 13' pontoon boat, any idea how many HP it would take to get it cruising at 10mph?

Thoughts?

John
