Re: Diablo dreamers,builders and owners.....
initial stability:
I can stand on the gunwale of my diablo and dive off it. I weight
200 lbs. No problem. (this is a calm water activity).
1/2 " thickness is fine with a 10 hp motor. With a 40 I am surprised
the bottom even touches the water. This sounds dangerous to me. Good
luck.
I added a plank keel from the bow to about 1 foot from the stern to
help in low speed maneuvers i.e. trolling for bass and blues. The only
problem is that it effected the natural drift used for fluke fishing
and it is a pain when landing on a beach to dig clams. I will probably
remove it.
I wish I had a 15 hp motor.
Happy Diablo building.

relatively narrow shape has a lot of advantages. I find it isn't
wobbly, even at rest--a reminder that for stability, adding length is
almost as effective as adding beam. And at speed, the hull holds its
course through confused seas, which means that you can run fast
standing up, to see what obstacles lie ahead.
I installed two stringers between frames three and four, and that
helped a lot. But running fast in a steep chop you could still feel an
unnerving flex in the bottom, and all that movement was knocking the
paint off. So this winter I've flipped the boat, ground the paint and
glass off the bottom, laminated on another layer of half-inch AC ply,
taped the edges and glassed the works. Should be a lot stiffer, and
will also be a couple inches narrower on the bottom (because the taper
of the bilge panels is carried over).
I've never felt the need for a skeg, even in tight turns at high speed.

Tim,
Do you have photos?
Where are you located?
Did you stretch the whole thing, or just the straight sections?
I don't think you'd need to repaint inside of the Grande, just the visible
parts. I'd coat all the ply (inside & out) with epoxy and very light glass,
and leave dark places unpainted. I'm not sure what the plans call for, but
I'd enclose most of that raised deck as flotation chambers. On other boats,
I've found that fore-and aft seats/chambers, draining over through generous
scuppers, shed most of the rainwater, and even forgetting the plug, to fill
up the "cockpit well" with water, doesn't do such terrible things to
stability. I'm considering this modification to the Diablo I bought.
You say you'd like more beam. Why? I've found the 15' diablo a wobbly boat
(initial stability), but very reassuring in use.
When you say the 1/2" bottom is light, what do you mean? I get some
oilcanning even with a 15hp. Do you have a skeg or runners on the bottom?

The South Street Seaport maritime museum in New York built a (regular)
Diablo for a yard boat some years ago, and the people there were
reportedly delighted with it until a hurricane picked it up and smashed
it against a seawall. I've often thought that if a hurricane did the
same to my Diablo, I'd build a Diablo Grande as a replacement.
If it's any use, my Diablo is a stretched and beefed up version, the
same length as the Grande (18 feet). I built it this way because I
wanted a slightly bigger boat, and Bolger hadn't yet drawn the Diablo
Grande, and I didn't dare mess with his lines except to perform an
elementary stretch--easy because all the lines aft, except the sheer,
are straight.
It's an awfully good boat, and Phil blessed the stretch on seeing
photographs. With a 40-horse motor, it makes about 22 kts with four
adults aboard. The half-inch bottom has proved a little thin for all
that power, though, so this winter's project has been to add another
layer of half-inch ply. Modification is nearly done, and I'll post a
report on its performance when the weather improves.
We've got more boats than I care to admit in the family fleet,
including four Bolgers, and I'd say this one has given more pleasure to
more people than any other. The long, skinny shape has advantages,
particularly in muddled and/or following seas: the boat tracks like a
train. But there are times when I could wish for more beam and
freeboard, and at those times I start thinking about a Diablo Grande.
One hesitation about the Grande, though. The plans show the boat
decked, with hatches to be removed for footwells and scuppers to drain.
My Diablo needs paint every year; I'm not sure I'd want to get up under
those decked spaces all that often.

Greetings Diablo Bolgerites,
Just went surfing on the net and found this:

Thought it might be of interest to the little"devil"in you!
Sincerely,
