Tom
Such words of wisdom have seldom been spoken on this forum, especially with lady passengers aboard.

I guess that range isn't the problem, it's the duration that becomes an issue after three cups if coffee...

Yes, some people at shows indicated they really wanted a boat wit at least basic "accommodations".  Still haven't sold it, though.

[Electric Boats] Re: New Boat Purchase - Have Questions

 

If you don't have a towing package on the Outlander, see if you can get one added. That may boost your rating enough.
Otherwise, add/increase your transmission cooler and rear suspension, then drive carefully.

Re: [Electric Boats] Marine Heads

 

The portapotti is really the way to go for a head on boat.  We operate mostly on Tomales Bay which has no pump out facilities, so it's the only solution.  However, having had one on our 30' LION for some time, I wouldn't go to a standard (and often troublesome) marine head and holding tank if we did get pumpouts.  The porta version is easy to use, easy to empty, substantially odor free, and takes very little space.  Reccommend them to all my friends who ask me  .. or I will if any ever do ask...

Re: [Electric Boats] Spincraft Silent 1 video fuel cons. claim

 

There are sure some fine e-boats on the market.   Dennis Wolf's is a beauty, and the Grapeview point boats are too. This Spincraft is a very pretty little boat too.  However, listening to the video on their site (http://www.spincraftboats.com/video/spincraft.wmv) I was taken aback to hear them claim that while their boat will run on .9 liters per hour (gen set), a normal diesel boat of this size will use about 4.5 gals per hour.  Really?  I know of a 50' x 14' trawler that goes 7 knots on 4.5 gals/hr (671-N).  Are they ignorant or just think that we are?

Subject: [Electric Boats] Spincraft Silent 1 for sale

 

Am thinking of selling my 2006 Spincraft Silent 1. It's the basic model--no fancy woodwork. Same colors, trim, etc., as in picture at http://www.spincraftboats.com/. I bought it new. Have a trailer for it and a guy that will deliver it fairly cheap. I've added a surrey top and another battery--for the bilge pump. There's an OK cockpit cover. The boat's a little big for where we have it--a lake in upstate NY--and we have a smaller homebuilt one we put on the hard when we got this one.

If you or someone you know are interested, eMail me at sweeton@fastmail.fm.
