70 mph DF 33

[egneg]

Yes that rooster is wasted energy as you know. Looks good but does nothing. I know you would have cupped the prop so I wont ask.
If you look close at the picture that shows the damaged hatch you will see another little trick I used.

Paddy my eyesight is not what it used to be ... I know it isn't the ton of tape on the boat.

Actually it is what I have done with the tape in certain areas of the hatch to get the air to flow better. I would like to design a more aerodynamic hatch for this boat. 2/10th's of nothing I know but it makes me feel better.
It is a pity I did not tape the whole hatch and my repair would be a little easier as I would probably have the broken pieces I could just epoxy back on. Now some fish is looking at them and wondering who or what polluted his home.
Time to get the BBY rigger ready for more fun tomorrow morning.

Ok ... that makes sense. I was wondering why you had tape in areas that didn't help seal the boat.

Paddy I should of told you about the thin hatches, it is the same on the original!! I used some glass on the inside to strengthen then just epoxy and micro balloons to fill the damaged area. Sand and paint. It comes up OK and once you strengthen the hatch from the inside seems to stop the problem of the glass flexing and cracking out the gel coat.

[andym]

I don't have any video but my rooster was much higher leading me to think I need to adjust the stinger a bit

Chuck how high up is the bottom of your strut? Also looks can be deceiving, when my stru is level with last 4" of keel it appears to be angled down when on the stand. I have found that with anymore than a tiny bit of down angle my DY will stuff itself when on chop over 55

Thanks Andy. I will repair it as you said.
What can I say about your props. I to you and to you.
Well mate the new DF 33 might be handy when it gets here if this one keeps blowing over.

[andym]

I think there is some credence in the 2 pack here, it has great attitude when running just to light when it hits its wake at 116.

[egneg]

Andy the center line of the stinger is 8mm higher than the keel and the stinger is 89 mm from the transom. So the prop (modded Prather 225s) is about 95 mm from the transom.

[andym]

That sounds about right on the height and I found the length from the transom has more to do where it is in relation the the rudder although my handling improved when I cut mine back to 60mm.
Never liked that prop much at all, found it slower than anything else

[egneg]

So maybe a M645 would be better as this is what I had planned on at the beginning,

[andym]

What motor, esc?

[egneg]

What motor, esc?

Neu 1515 1Y and an Etti 150.

[andym]

What is the hull in the pic? It is not a DF, looks like a Rico?
I the m645 with mods for calm water and a m447 on chop, both with a little cup at the tips and back cut a couple of deg. The 47 also likes a little bit of edge cup, not much though.
The fastest two props I have tried are a x648 cut back to 47 and a x447/7 cut back to 46 with a lot of mods to unload it,

[egneg]

The hull is an El Lobo IV. The 225 has a bit of tongue taken off and is back cut. I will cup the 225 a bit and see how things go. If things don't improve I will go with the M645 cupped.

Cool
