How thick is the glass on your Trawler Doug?

Is it thick enough to be bullet proof?

OTOH in our present boat, we don't worry about Bayliners or drunk
fishermen ramming us, they'd come out in 2nd place and know it.

About 3/4" most places. I think it's resin-rich though, with a lot of mat.

I think so, up to one of the larger magnum rifles at least. But I
wouldn't want to put it to the test.

he had to do to win was finish. And finish we did at 3AM (race
started at 1PM. No committee boat but his understanding is since
there was no time limit on the race he just had to cross on the right
side of the sea buoy that made up one half of the line.


Umm, did they actually award this genius a finish time for doing this?

My understanding (from my brother-in-law) they gave him the cup. I
never saw or talked to him again. This all happened in the late
seventies.



While bobbing around out there, this fool had us doing all kinds of
idiotic things to get the boat moving. For instance he had read in a
dead calm if you ease forward and then run briskly aft you will make
the boat move. He actually wanted us to do that.

IINM, that sort of thing is illegal under the rules of racing.


Not only is it illegal, it's very counterproductive *unless* the crew
practices the moves to get some actual measurable propulsive effort. The
best way to get the boat moving & keep the boat moving in a drifter is
to have the sails trimmed properly and keep everything absolutely still.

One of the benefits of regualr racing is that you get a chance to
actually try out rocking, pumping, sculling, etc etc, when there are
other boats next to you, and see if your technique helps the boat move
faster. Then you watch other doing it, sometimes there are guys who are
quite good at it. You work at improving, until you can make the boat
move that way.



Most race skippers will provision their boats for the crew. He did
not and told us when we found out before the race that we did not have
time to get some food and beer.


I'd have left the boat right then. Dehydration is not a joke.


The only reason I didn't pitch him overboard was because of the
Brother in Law.

LOL - great post mate!

PS: surely there *would* have been a time limit, or at least, one should
have been imposed during the race when the wind dropped, and the course
shortened. Was a radio not a requirement?


Apparently not.

There is something to be said for a bullet proof
boat. It would be nice to have one that wouild
stand up to a .223 assault rifle calibre.

What is your fuel capacity and range?

I can only think of one person I wanted to toss
overboard, and two I wanted to shove off the
dock.

Restraint is an admirable quality.

I was telling some people about one fellow who
****ed me off and when they heard the name, they
all laughed because they knew him. Can you imagine
having that notorious a reputation?

Daedalus would be foresight and thinking ahead.


No, I don't think so. Daedalus made the boy a set of wings held together
with wax but did not evaluate Icarus' lack of common sense and so Icarus
flew too close to the sun, the wax melted and he paid the price. So
Daedalus failed to think ahead at all.

Well, Kevlar isn't that expensive. Actually a heavy gage Dynel laid up w
epoxy would probably be effective at lower cost. You could put it over
key parts of the boat... I'm thinkin about the forefoot, keep those
shipping container worries to a minimum.

Polyester & glass layups tend to not have great impact resistance, but
there are laminates that do much better.

What is your fuel capacity and range?


350 gal, I figure we've got 1200nm (2gph @ 7.5k) easy and probably 1600
if we go slow. I am going to add some fuel capacity by putting bladder
tanks under the aft cabin. I think we can add another 150 gal that way.

DSK

I spoke to a fellow that has used it, and he
told me that sanding kevlar leaves fibers poking
out of the surface. He recommended either
fairing it, or laying it up with one layer of glass
on the outer layer for fairing.

Have you used it?

An extra 150 gallons is nice. That's 42% more range.

Very nice.

What material are your tanks?

Yes, and your friend was right. There is no way to sand a Kevlar lay-up
smooth. I helped a friend put a layer of Kevlar on the bow of his
catamaran, we used a layer of medium density fairing compound over it
and ther are a few spots that show stubble... you have to look real
close, and after painting on anti-foul it's not visible. I hope no
future owners sands the forefoot(s) (forefeet?) too agressively.

A better method might be to lay a layer of very fine FG cloth over the
Kevlar, or a light type of scrim. Or, if you're building the whole thing
from scratch, put the Kevlar in the middle of the laminate.

I was thinking of using a mix of Kevlar and carbon fiber on the dinghy,
but have decided to go with just CF.
