Hook

[Foggerjet]

I think I understand how to measure hook, with a straight edge and all. My ? is does the boat need to be off the trailer to accuratly measure this? My boat sat on the trailer for six years without moving, and a friend said I should measure it. On the trailer it has none. Is it possible that it could have some while in the water? I'm an amateur so please don't bash me too bad. Is hook a problem at all speeds or just for y'all fast guys?
thanks

I would say that it is a problem .Taking the hook out will let the bottom free up witch results in MPH.Will a boat run with hook for sure but same power set up with out the hook will give you more mph.
Did you measure about 3 to 4 feet down the boat that is where you will find the hook not in just one or two feet and at least check it 2 strakes up.
I do not think the trailor will interfear?

If you have hook, you will see it on or off the trailer. Eyeball each strake as a quick guesstimate, then measure it like hobojake said.
Got an extra hot hamsan there jake?? Go good right about now.:D

But what do I know!

Thanks guys. I used a long straight edge for checking cummins blocks for warpage. about 4' I guess, and came up pretty far up the bottom. I measured virtually none. This is the first time I've even attempted to measure this, and I could have (easily) done in wrong.
Thanks for the input.

Best bang for the buck in MPH ,but does not sound like you have much hook in it ? Nothing like the first trip out after you remove the hook in one ! My case mid 70's Thahiti HEAVY ass water plow , ( Which Is For Sale ) water coming off the boat was about 2' in front of me ! Removed the hook about 1/4"and the first thing I notice was water now is about 1' behind me ,next thing was the boat is now FLYING off the rollers instead of pounding through them and the most important one was STOPPING IT , coming in I was heavy in the pedal and trimmed up high enjoying myself and coming up on the no wake zone well, after I got out of it I was still getting it on past the bouys and I was looking in the cove for the man and grabbing some reverse! Bottom line If you got it ,get rid of it :D

I dont think it's your eyes pal. (although they might be off a little having the glare from all the gold you have around your neck shining in them all day long) You just have the money to have these things done for ya.:D I dont think you ever looked at the bottom of your boat while it was on the trailer. Why should ya?
Here's a little trick HB....you have to get your knee and possibly your hands dirty though....get down on one knee at the back of a boat that has/might have hook and look down the strakes from the transom forward and tell me what you might see ok??? Better take off the rope chain before you do though so you can actually see something other than glare. LMAO!!

Chester What I didn,t get quoted but HBJet did I think I gona ****n cry.
Jake:cry:

[dgie]

when you flip the boat over are you setting it on a craddle of some sort , also how do you remove a hook if you have one?

[Jake W]

Dgie use what ever you have to work with old tires a nice cradle, foam and your trailer.
You fill in the gap from strake to strake.Resin and glass,or some type of sandable poleyster filler like Rage gold and so on.At least do about 4 feet from the transom forward.
Jake:D

[shaun]

my boats been sitting for pretty much the same amount of time on the trailer. I assume a 'hook' is when the bottom is no longer smooth and has a lip or some thin of that sort? Where and what exactly should i be looking for?

[squirt]

Look at the photo above and notice the gap between the metal stright edge and the hull. That is the amount of hook in this hull. That is not alot of hook but the owner of that boat wanted to achieve higher speeds and better handling so he had the bottom done. That boat ran in the 80's with that ammount of hook with a fairly stock ls6 454.

[dgie]

4 feet forward of the transom all the way forward?
Is it better to use glass and resin as opposed to filler or are they about the same?
Last but not least can you use bondo? its a polyester filler (I think) if not what are some other fillers.
I ask lots of quesions, I know :D

[Jake W]

These are some questions that a person that does this all the time need to be asked.
I would not use the Brand Bondo for any thing.
I would think Resin and glass would be the best but much harder to work with opposed to Rage gold witch is great stuff and sands really easy.As I understand it you can gell coat over any kind of poleyster products.And if you use speed coat that shit will stick to just about any thing.
Fill in the low spots or hook 2 strakes up on both sides 4 feet (from the back of the boat forward) or transom forward.
To be redundent from back of the boat measure 4 feet and fill in that area that you just measured.
Jake:eek:

[dgie]

Thanks Jake, I may have more questions later on this subject . I figure I should check this while my engine is out, I figure the bottom of the boat will be just about as interesting as the transom that I replaced summer before last. Also it gives me something else to do, what could be better then that. :D

Chet, since I paid an expert 450 dollars for 2 full days of work to fix my hull, you think I made a mistake and I should have done it myself like you.... which took how many months?
Yes Chet, I have looked at the bottom of my hull before I had any work done to it, and yes, I know what it's like to get dirty. Before every trip to the lake or river, I make it a habit to get under the boat and check everthing out.
Sorry that I can afford to have professionals perform work for me that I know I can not do with the same level of quality and perfection.
As for the hook removal, my boat didn't have as much as others I have seen, but having it removed was probably the single biggest "bang for the buck" (put that in there for you Chet) out of everything else I had done to the boat. For one, the boat ran flat, and it was alot more loose. Which in the first 10 seconds feels weird when your used to a certain feeling the boat give ya, but you get used to it. For me it was almost like driving my truck in the rain, or on wet roads and the feeling you get when the back tires free up and the truck drifts a little... it was kinda like that feeling at first. Basically you no longer "stuck" to the water. The boat did seem quicker and yeah, it took longer to slow down... One of the biggest problems I had before having the bottom done was in choppy water, I would have to trim up a little more then usual to get over the wakes.... but when you hit one just right (or wrong) the boat would kite up into the air as if it was a tunnel and then come back down. The reason for that was I was too high on the trim, so when the bow would lift, the pump just kept pushing it forward and up until gravity took over. If you weren't ready for it, it would catch you off guard.
I did a little write up on my hook removal at www.op6c.com here (http://op6c.com/forums/index.php?act=ST&f=18&t=1333&)
Here are some photo's though...

Here you can compare my inside strake and the outer one (which doesn't touch at high speeds
http://www.hotboatpics.com/pics/data/500/3fix032.jpg
And here is the boat running at 5200rpms with air temps over 120 degrees.... it was a hot weekend. Highest I think was 128. Anyway, the motor turns 5800 at WOT.

No hb...i NEVER said you made a mistake. You boat was in new condition compared to mine dont forget. It took months only because it was worked on nights and weekends for a few hours at a time here and there. NOT FOR MONTHS STRAIGHT. Looking at your pics hb...i just learned something that i just might use if i get ambitious to "tweak" my setup.:idea: Thanks pal! All those bad things i say or ever said about you....i lied! LMAO!!

No Chet, I check the hardware to make sure everything it tight. Don't want any bolts comming out when I'm on the water. And when I'm down there, I just happen to look at the hull.
Glad I could help you.... But I thought you sold your jet boat?
