the threads are 9.5mm long,
if you want longer, these can be about 15mm long but I don't like them

you can glue a square piece of something (teflon or else) or a small tube with the nut inside to the hull edge to achieve the required distance

By the way, Fluid has helped many people here, who is the fastest can be only found out when racing next to each other

Do you have any close up pics with the hatch off so I can see how you glued the nuts? Its just the nuts that are glued, they dont come loose? I have been debating how I want to do this and considered making aluminum thread bosses for the knurled screws, but there would be no nylock that way.

[DISAR]

Another way to secure the hatch is described here in post 15, with knurled nuts glued to the hull and countersunk screws, often seen in German boats

A way to lock your hatch down is
a) Thumb screws from ebay (http://cgi.ebay.com/Aluminum-Anodize...item43a623c581)
these are 3mm
b) 3mm lock nuts

This is very good information, i was looking for something like this. How long are the threads?

Comparing your FE experience with Fluids, and talking down to him is downright laughable buddy. He never disrespected you. You're not gaining any respect from me, that's for sure.

Must be an awfully long pond to run 100 mph for 3 minutes straight....

3min of run time

Howard, there are at least a dozen 120 mph FE cats in the world, yours is very fast but hardly the fastest. When I set my P Offshore record that cat was the fastest official non-rigger FE boat in the world - can you say that? Didn't think so. I wish you well with your endeavor; you can claim all you want, but I'm through here. Adding another one to the ignore list.

I don't think i have the fastest cat in the world, i was only making a point. You come on my thread and talk about me like I'm never going to read it. You talk about experience like you have a boat that can beat me. When i run a 100 it was for 3mins and my motor temp was 134 and the esc was 147, can you say that? Now that takes real experience, I'm not pushing my motor or esc to the limit yet. I just want to help the guys that are looking for a good top speed without all this drama.

through all these pages I for one am learing a few things (actually lots) on how to make my Genesis into a fast Cat!

amazing pride, so sad

I got out for some testing and no luck with props. Fluid was right the 2047 has a lot of lift, i adjusted my prop angle to 5.3 and it started to look better. I just stopped right there, I'm not going to offset 1 thing to make another thing work. I like the abc (1.9 1.8/2) prop if there is someone that can set this prop up for me. I was talking with Benjamin with fightercatracing.com to see if he could come up with a strut/rudder that has a offset and is a 1 piece. This is a MUST for a single motor setup. I would get with him on the details. Also i was talking with him about a way to lock the hatch down, this is also a must for making high speed runs. I lost my 1st 32 from a high speed flip and only having tape holding the hatch down. Yes, a new boat with only 2min of run time sunk, a very expensive lesson. I said i will made a vid of this 32 at 100mph and i will, just waiting on the right prop. Looks like the props cater to hydros.

A way to lock your hatch down is
a) Thumb screws from ebay (http://cgi.ebay.com/Aluminum-Anodize...item43a623c581)
these are 3mm
b) 3mm lock nuts
c) place the hatch in place, drill 4 holes 3mm on hatch and hull edge, glue with epoxy the nuts on the hull edge. Glue with CA on the underside of the thumb screw an o'ring so that as you screw it down to the nut the o'ring will make it waterproof and will not damage the gelcoat or paint as well.

Have it like this or with 2 thumb screws at the back and 1-2 carbon rods-tubes fwd sliding into drilled holes.
Here is my sprintcat with 2 thumb screws at the back and 2 carbon rods forward. In this way I never had the hatch off again.

Someone's getting a bit of a chip on their shoulder, no?

Your right my experience mirrors your own but you forget i just might build the fastest cat in the world, can you say that?

I didn't care at all how the hardware handled, most of these narrow cats suck at turns anyway. For straightline racing it was unbeatable, the best I ever used and I used a LOT of strut/rudder combos. Howard's experience here mirrors my own.

I cannot understand how you guys are losing your boats when just the hatch comes off. Don't you know about flotation? The only race boat I've ever 'lost' was a wood-on-foam cat which broke apart in an 80mph crash. I recovered the sponsons and the deck, but it spit the guts out over 20 yards of lake. No more wooden SAW boats for me.

I would say you just put your foot in your mouth on this 1. Your right my experience mirrors your own but you forget i just might build the fastest cat in the world, can you say that? Mr experience! Building a cat out of wood and racing is something i would never do but then again my first run i did 81 on low batteries. You talk about the records you set but never at what speed. And my boat didn't just sink i just didn't choose to go in for it. A hatch lock is not just to keep your boat from sinking but it keeps the water out. A small drilled hole in your hatch might let a little water in but its nothing compared to half of your tape ripping off. I use a small piece of foam to seal my hatch and no tape. Come on fluid no more hating.

[Brushless55]

Not to get off the subject too far-pipe insulation is MUCH better than pool noodles. A friend of mine ran his new mono for the first time today and has floatation in the hull and none for the hatch. Guess what he lost?
Keith,if you go to the pool this summer,take pool noodle and pipe insulation with you."Sit" on both in the water(you know what Im talking about)for a few minutes.Stand up and wring each out,one at a time and see which holds the most water.

Might have to try this stuff out, thanks for the tip!
