Hear's the think that everyone misses and really pisses me off. First the Duck Boat is not a boat but a
'Duce And A Half' frame and motor made into a landing craft. It was not made as a tourist boat! The
tour operators added a enclosed structure to extend operating hours in cold and rainy...
Well if something is going to break I'd rather it be the mast than the mast
tube. The picture looks like the mast broke where the goose-neck rubbed.
The scratches and wear probably set up stress risers in the aluminum. The
best answer it probably a new 'zero time' mast.
I do have a boom...
The main problem is the hardware is mounted with wood screws. The would have
worked when the boat was new. You need machine screws with lock-nuts and fender washers.
Easy for the stern as that's where you put a inspection port anyway. You'll need to pop
the deck or put in a inspection port...
Definitely a no-go as indeed the deck is thin and the wood blocks never designed for lifting. Best
would be to use a couple straps under the hull. Could you pop the front and rear deck and
reinforce? Yes but light weight is everything to a Sunfish. You could put a couple handles
I would think a MC Scow would be the logical choice from a Sunfish. You get
the hyper adrenaline speed rush and the necessity of team work in higher winds. All
depends what's racing in you area I guess.
The hole in the cockpit was for older Sunfish with the color deck which would get
hot. The air inside the hull would heat up then contract. With a plugged vent hole
you could actually watch the deck get sucked inward. The transom plug only works
if the boat is on a uphill slant since the low...
Those were the 'Dread 71's' where there was no flange on the cockpit tub. Sitting on the deck would cause it to
crack the deck 360 degrees around the tub. Who ever thought attaching the deck to the tub with a 90 degree
butt-joint must have been smoking something. Then again we were all...
I would not think more than 100 Dread 71's were made before they realized there
was a problem. If 300,000 Sunfish have been produced to date the chances of
coming across one are almost nil. There was one on this forum some years back
and it was not worth trying to fix. Luckly, it's not a...
I'd check for the rare but not unheard of 'Dreaded 71' problem first. Chance is if
it's made it this far without problems you're probably not a recipient of one.
Anyone known how many boats were recalled?
Time to break out the Dremel, Fiberglass cloth and mat.
The hull supports the tub and the tub supports the deck. Somewhere this is not happening so first check where
the tub bonds underneath the deck and see if it has come loose. Then push on the hull underneath the tub and
see if it flexes. There were a small amount of Sunfish made where the...
Snark sail area is 45 sq. in., Sunfish is 75 sq. in.. I can't see this boat being
useful for learning sailing, more like a beer drinkers challenge. Snark sails
are available on E-Bay for not much. I'd buy a new sail rather than destroy
a future sailor through the frustration of trying to...
That's the way I did it because I already had holes in the cockpit floor. All the extra foam expanded horizontally.
You should be able to do it by reaching in through an inspection port. Most older Sunfish have cracks in the
tub because it is unsupported. Kids jump up and down on it when the...
The cockpit tub only contacts the hull at the outer edges. The factory was using glue pads somewhere along the line to counter the flexing. Also the hull was stiffer when new. It becomes a problem plaining-out when you hear the hull go 'braatttttt.. .' Fortunately the fix is as easy as...
If we go by sail area the Porpoise board should have 13.3% greater surface area in the water.
So we increase a Sunfish daggerboard from 40.24 to 45.64 inches plus 1.5 inches for the hull depth for 47.14 inches. For width we are just a little over 9 inches wide but since it is such a small amount...
Sunfish has sail area of 75 sq. ft. Super Porpoise is 85 sq. ft.. Scale the length
accordingly and use mixmxr's suggestion for the rest. Unless you're into racing there
is a hole lot of 'Fudge Factor' to work with. A good airfoil shape will probably be much
more important than small length...
