Posted: Sat Apr 10, 2021 2:35 pm Post subject: Centering boat on trailer |
|
|
when I pulled the boat out of the drink the other day there was a nasty breeze that kept the boat pinned against the port side bunk board guide,,,,,,arrg. Years ago I made an over engineered, clunky gadget that slipped over the side boards to help center the boat on the trailer. They got lost somewhere and that was fine but it got me thinking about engineering up a new gadget that could be slipped onto the side board to center the boat when loading and then be removed for transit and cleaning.
After completing two pages of calculations plus three pages of detailed drawings I have come up with the perfect solution which I'm now selling for a low introductory price of only $49.95-

maybe I'm finicky but I don't want the boat to be in contact with the guide bunks, these beauties will hold the boat off the bunks so the guides wont be rubbing on the boat _________________ Ken

Ken, Did you get the gloves and hand shovel too. What do you use that trowel for
OK, for real. I looked at the pads but not being privy to the 3 pages of calculations, drawings and cogitation, how do you use the knee pads. I'm pretty sure you are using them in an off label version.

i figure to strap them on the guide bunks to act kind of like a fender to hold the boat off of the guide. I'll take them off once the boat is loaded and I should have an inch or so gap between the guides and the boat . Right now my boat is right up to the guide on the port side with about a 3" gap between guide and boat on the starboard side.
I was just thinking these things may not work, they'll be submerged and as i pull out,the boat may be set on the trailer before the pads contact the boat |

I use about an 8” long 2X4 screw to a piece of 1/2” plywood with carpet on it. I tie it to one of the side boards just above the rear axle. The boat always moves to one side of the trailer. When I pull out the boat will shift to the right and up against the 2X4 pad stops the boat dead center. Then remove it when I’m out of the water. _________________ Jody Kidd

Well....if you already have side bunks, a chunk of 4" x 1.5 " c-channel aluminum and a 2x4 screwed to it works really well. And what even works better, is not really caring....lol..... |

Just the idea I needed -- have the same problem -- the boat always rests against the starboard guide rail.
Found this plastic board in the scrap pile -- was just the right 1 in width.
Today, retrieving from Bayfield, WI ramp:

Centering a CD25 on rollers with any breeze or current at all is a nightmare. Our worst ever experience was at Bullfrog at Lake Powell, the lone dock there was occupied a houseboat so we had to drive the boat on to the trailer in winds a little less than a howling gale. I still am not quite sure how we did it.
However, we once did find the perfect answer. After the river test of our new Suzuki 200 at Sportcraft, they had one side up on top of the trailer fender on the starboard side. We told them we would not drive it home that way, and we talked about how they might center the boat. Finally, they rounded up four guys to push it over to the center. It took something like four or five concerted pushes. Unfortunately, those four guys declined to always be available for us whenever we retrieve.
So if anybody has a foolproof was to center a CD25 on rollers, we would love to hear about it... _________________

Side bunks PLUS Stern Roller Bunk Glide - On's |
Your link goes to the thumbnail version, below is the full-sized version. Can you explain what it is and how it works? It is not self-evident, at least to me. And you have bunks - does this concept have any application for roller trailers?
Thanks.

I don't see why it wouldn't work just as well for roller bunks. I just went outside and looked at my trailer, these vertical roller bunks are set / positioned as far back on the trailer as possible and as close to the sides of the boat as possible. Closer than the side bunks. When you are loading your boat these roller bunks prevent the rear of your boat from floating from side to side and help to position the boat so the side bunks can do their job. Before I bought these I was having a hard time loading my boat , now I never have any problems. I just have to crank the boat in and it centers every time. |

Why not just get the boat centered once and move the side bunks in a bit? The bow is narrower than the stern, if the side bunks are tight, it will self center (as long as the side bunks are high enough and it doesn't sit on top of them).
On the float on trailer for my TomCat, there are guides between the sponsons that are fairly tight to the sponsons once it is fully loaded. Since the sponsons also have a pointy bow end, the boat fits nicely around them and self centers as I go forward. It seems to me the same thing can be accomplished with the side rails alone _________________ Roger on Meant to be |

Roger,
The Tom Cat hulls are about the same beam amidships as at the stern. That is not true for the 22 and 25. (and many other boats). The beam is greatest amidships and then tapers in aft. I don't have the exact dimensions, but there is several inches difference on each side. My guides for the 25 are tight amidships--about 4" less on each side aft. Not true of the Caracal Cat, whose hull lines are remarkably similar to the 255. _________________ Bob Austin

We don't have side bunks or guides. We just have rollers and tall goal posts right at the stern end of the trailer. I like the solution from eTrailer that Mark posted. Probably going to order that after running it by the Chancellor of the Exchequer. |
