How common are 36 or 48 volt systems in marine use? Is there some specific
safety rule?
I want to make and sell an LED lighting system that gets much easier to
assemble and operate at these higher voltages.

   I'm looking for some boat plans for a small (18-24 feet) sailboat.
Something I can sail by myself but is strong enough to take on short blue
water trips. It should sleep 4. Plywood construction.
  I've found some plans for boats which would work. One extra fancy one

Here is an e-mail I got the other day, I kind of went nuts with the
answer, thought I would pass it along.

Would anyone have a suggestion for cleaning off/keeping off teak resin from
bandsaw blades?
I am having to clear the gum off daily and presently using 'easy off'  oven
cleaner. It works, but takes a good half hour a day.

I'm constructing a 10" tunnel hull and am at the point where I need to
seal/finish the interior of the hull before putting the decking on.  The
boat is not going to be left out in the elements or used in saltwater but
will be stored indoors when not used.

I own a 1942 83 Ft. Wheeler  (80 tons) and am rebuilding the anchor chain
locker.  My plans are to add a bow roller for the chain and to guide the
anchors.  Of course it has to be strong enough to handle the boat during
heavy storms/hurricanes when boat is anchored out.

I am removing teak from my boat where ever possible. To date, the teak
traveler blocking and hand rails are history, to be replaced with King
Starboard blocking and Stainless Steel handrails.  These former items
were fastened to the deck  with 5200 and bolts.  There remains now , a

Does anyone know where to get isolation washers. Specifically the cone
shaped plastic pieces that fit under the head of a flat or oval head
screw to galvanicly isolate the screw from the item being attached
(such as an aluminum stanchion).

What does / could  it mean to "fair out" the hull of a wood boat?
I assume that fair out means to sand it smoother?  Sand it to take
out any dips or bumps?  But can that be right?
Anyway, thanks.

The other post about canoe sailing got me thinking.  I grew up with a
Grumman canoe and still consider canoeing to be as natural as riding a
bike.  Its an old 18' Grumman Aluminum flat bottom canoe, nearly
indestructible.  I always wanted to use it to explore salt marshes and

Any info on this? The 12v single water clear led's are $1.67 and put
out 11000 or 3300 mcd, whatever that is, some measure of how bright
they are. The viewing angle is 30 or 60 degrees. The attraction is
that current draw is almost nothing. I measured .023 amps for a single

Question
Can anyone give me any ideas on how to remove about
five coats of ablative bottoms paint, short of sandblasting
or sodablasting?

I am looking for design ideas on limiting the tilt on my 4m single
axle break back boat trailer with a 65mm RHS centre shaft.
