Hook In Hull - How Much Is Too Much?

Re: Hook In Hull - How Much Is Too Much?

Nice boat, sounds like it performs very well, not sure I would do anything but run it like that and maybe try a 19p prop

Re: Hook In Hull - How Much Is Too Much?

Sounds good. Thanks a lot guys. It sounds like I need at least a 19 prop. If it can take a 21, then the 19 should be good for sports?

Thanks again for the help

Re: Hook In Hull - How Much Is Too Much?

Just bench-propping so to speak, if the engine can "take" a 21p without lugging then a 19p would be perfect for watersports towing.

There is a HydroSwift area you may want to visit, here is a link to it....:

I like to follow it but posts kind of sneak in there on me sometimes :embarassed:

Perfect. Thanks Maclin!

As others have said the hook in itself is not a big deal in your scenario. I soend a lot of time on performance boating forums and those guys (mostly 25'+ with huge sc power) absolutely freak out about a hook in the hull but they are pushing the 100mph mark

I was just concerned that it was running so flat, but it sound like it's just the design. Thanks.

I have a hook in my keel also. Keel is a continuous bar of aluminum 2" x 5/8". Mine hugs the water WAY too much, even though it is trimmed out all the way. I'm just living with it.

How long/deep is your hook? What boat/motor?

Thanks,

....and some of "those guys" have spent thousands of dollars fixing a hook (or rocker), only to find that the boat's performance didn't improve and, in some cases actually got worse. It's really a crap shoot.

I wouldn't worry about it. Didn't look like much of one in the photos, and it's more of a problem back near the transom anyway. Even then it may not be a problem as some boats actually have a bit of hook by design.

That's a very cool old boat. Classic lines. Gorgeous. I'd just enjoy it the way it is!

Thank you. Think that's just what I'll do!

Mark, sorry about the delay. Boat is an 18' welded aluminum hull (Crestliner) and 110HP Johnson motor. The hook is about 12 feet long and the hook is about 1/2 inch at the worst (middle). The hook tapers uniformly over the 12 feet. Decided to do nothing with the problem as the straightening process would probably break all the welds.

Regards, Mark

best move you could make in my opinion. I never was a fan of roller trailers....

Nowhere did he mention anything about what type of trailer he had. Most likely whatever he had was not set up right. A properly adjusted full roiller trailer will provide the best support and never deform the hull.

From the OP's first post: I have a 1964 17' fiberglass v-bottom runabout with a slight hook caused sitting on a trailer roller for years.

Re: Hook In Hull - How Much Is Too Much?

In my situation, I have a bunk trailer with keel rollers. The PO had the bunks adjusted so all the weight was on the keel rollers and there was no keel roller at the transom.

My comments were directed at a poster who commented on yet another poster, not the OP.

Now we get to the bottom!!! You just summarized the root cause of the problem. The trailer WAS properly adjusted, but the #1 critical part was missing.

The lack of roller at the transom is what made the hook.

There is a roller under the transom, but it does not contact the transom. The roller tabs are welded (not adjustable) to the back of the last cross-member, not on top like the rest of them (also not adjustable). It appears the function of that roller is just to keep the boat from contacting the last cross-member.

I built my first boat and trailer (yes, I built them myself) when I was a young and impulsive teenager. I read book after book so I knew what I was doing. Al went fine for 3 years. Then, I screwed up when I put her up for the winter.

It was a short garage, with little access to the transom. I had the wheels up on blocks and had removed the transom tie downs to relieve the pressure. For whatever reason, in my haste I winched the boat forward before I unhooked the line, and didn't notice that the transom had moved off the last roller, and thus was hanging in the breeze. The side bunks went all the way to the transom, but with no keel support come Spring I had a hook.

I would consider a trailer that had non-adjustable keel rollers (with 1 out of line no less) to be a poorly designed trailer. Welded or not, modifications can always be made.

WHY does your wife want a manual? Is she aware that she is SEVERELY limiting her options?

If manual shift was still desirable...manufacturers would still be making an abundance of them.

My advice would be to convince her that an auto tranny is the way to go.....OR....leave her to her own devices and let her struggle to find a manual shift. She will eventually give in and get an auto tranny.
