Re: Where do you carry your outboard when trailering?

I used to remove the 9.9 hp 2-stroke from my Aquarius and put it in the tow vehicle, and it was lighter than yours. I was concerned about the integrity of the transom. My A7.0 had an offset OB, unlike the A23’s (same boat with different rudder arrangement), and the parallel arm mount seemed adequate...

And as far as me giving Tom a dig, that would be like Forrest Gump giving a dig at Einstein. :D
More like Forrest Gump showing his war injury* to President Johnson. In public. Was it mooning, or just being very honest? :|

Re: Pulling a tube

I have a bridle attached to the two cleats on the rail. Dock line cleats, not the rudder cleats. I also put a small single-sheave block on that bridle, so it can roll along the bridle when turning. Makes the effective center of the tow line attachment much further inboard, which means the boat can m...

Re: Aluminum Trailer - Need help

That beam is weaker in the weak direction in bending by about 18%, and weaker in the strong direction by about 15%. And the material is a little weaker, too, which makes it worse. But it weighs almost the same (per unit length). It may be fine. Or not. I don't know what the various loads on those be...

Re: Aluminum Trailer - Need help

Capral was the first company but second look at the other manufacturer "Ullrich" (who manufactures only five I-Beams types) and there's a possibility with their biggest I-Beam (UA4389) that has a fair amount of "meat" on the flange and the web.... What do you think guys? ... Thought maybe Tom could...

Re: Aluminum Trailer - Need help

I don't know much about aluminium, but I do know that T6 condition is the result of several heat treatments (quenching for hardness and strength, maybe followed by tempering for ductility and stress relief and/or whatever. So I definitely would not use heat to bend it, assuming it's not in the lowes...

Re: Aluminum Trailer - Need help

My inclination would be to bend it cold, but I'd have to research it. Maybe Tom can weigh in on heating 6061 Aluminum to bend it. He's way better at Material science (and most other stuff too). I actually have a second degree in Materials Science and Metallurgy, but since I've never worked in that ...

Re: Aluminum Trailer - Need help

Yes I can weld and need to investigate the potential consequences of cutting and welding the bends, even if it means bracing the bends I don't mind that but need to be sure I (or a pro welder) is not going to affect the integrity of the Ali.... An Ali Trailer no stronger than Ali Foil is not so goo...

Re: 26D Mast Raising system

If you attach the bottom block or static line to the forestay chain plate, you won't be able to use the MRS to pull the mast forward while you pin the forestay. I would attach it somewhere else.

Re: BWY Disc Brake Kit

Don't forget that disc brake master cylinders are different than that for drum brakes. Drum brakes hold a residual pressure, while disc brakes are vented completely when the brakes are released. BWY offers a cylinder for retrofit, but it's much cheaper than the full-on replacement cylinder, and I do...

Re: Aluminum Trailer - Need help

You’ll need to know the flange thickness of those beams, too. Web thickness usually is secondary to flange thickness, or at least it is with steel W-beams, but the beam properties (section modulus and moment of inertia) depend on those dimensions. Material strength is also important, not for stiffne...

I agree especially about having a qualified dealer/service center as close as possible, especially if you're based in one place primarily, as opposed to doing the Great Loop where you won't be near any one dealer for very long anyway.

Re: Water ballast

Except that on later :macx: boats, if you don’t move some of the heavy stuff back after trailering and let the ballast fill without paying attention, you can get just a bit too much water at the vent. Or out the vent, I should say. Something you only do once. :|
