Location: Hayward, WI | I've been the proud new owner of a 2008 1760 GT for about a month now. Have not had it out nearly enough yet but I've been impressed by it more each time I get it on the water.
Have a question on the trailer bunks though. The two center bunks do not contact the boat at the transom. I can wedge a finger between the hull and bunk on the left side, and maybe my pinkie on the right side. They seem to lose contact about 2 feet forward of the transom. I want to get this fixed as I'm assuming these are the primary support of the boat vs the shorter bunks on the side. This is a Trailmaster/Tufftrail trailer.
I'll have to try to get a picture of the situation, but I'm not sure how this can be happening. The short outer bunks are making full contact with the boat, and the brackets are all welded on. The only way to adjust height would be shimming the bunks. The long bunks don't appear to be warped in a way that would cause them to make contact at the front and middle of the bunk but not the rear, but I can't think of anything else that would cause this. Also, since the outer bunks make contact, it seems like the welded on brackets should be allowing contact at the very rear on the center bunks too.
I can understand not making contact between the bunk brackets, but seems like if the two outer bunks make contact at the transom the inner bunks should too.
Again, will see if I can get some pictures, but does anybody have any ideas I might be overlooking? |

Location: Hayward, WI | I attached some pictures. You might also notice that the center bunks barely come to the end of the transom, and the outer bunks end short of the end of the transom. I'm thinking I probably also need to adjust the winch post forward so the back end of the transom is supported by all of the bunks. Maybe this isn't necessary, but other Tuffy pictures make it look like the short outer bunks and at the transom and the longer center bunks extend past it slightly. The tongue weight seems fairly high, but I'm used to lighter aluminum boats. Was thinking if I moved the winch post ahead, I'd move the axle also, but with the fenders being welded on, I'm guessing there is no moving the axle forward? With all this said I have not measured/weighted the tongue weight yet, and am not nearly as concerned about position on the trailer as I am the center two bunks not touching at the rear of the boat.

Location: Rhinelander, Wisconsin | You may be pulling the boat down at the bow with a bow stand that's adjusted too low. Disconnect the bow rope and see if the boat will sit correctly when it's not cranked down with the winch. |

Location: Hayward, WI | Thanks Steve. From memory is seems like the post is adjusted so it's pulling the bow straight into the bow stop rather than pulling down excessively, but I'll check it out. It would seem like if that was the case, the shorter outer bunks would not be making contact at the rear either, but it's worth looking at.
I'm not in posession of the boat right now, but when I get it back I'll take a look at the bow stop position.
Any other ideas of things to check, let me know.
Thanks. |

Location: Hayward, WI | I tried releasing tension from the bow hook, and there was no change in how the boat sat on the bunks. Looking at the bunks with the boat off the trailer, they don't seem warped. If anything the long boards seem slightly sagged in the middle between the bunk supports, like bunk boards often look.
Any other ideas of what I can check? The swiveling brackets seem to be adjusted to the same angle. The right center bunk very nearly touches the boat right at the transom, while the left center bunk has a significant gap as shown by my pointer finger in the gap.
Thanks,
Tucker
P.S. The trailer has been washed since those pictures!

| after reading this thread I got up and walked to the back of my 1760 to take a look and all 4 bunks made contact at the transom . yesterday I happened to notice a gap on the port side. it does not make contact till about 3 feet forward. The others make contact all the way to the transom. this is after using the boat last weekend/ loaded the boat 3 time and trailered home 260 miles. measured boat to fenders and found it is 1/4 inch off center. I find this interesting but not too concerned right now. |

Location: Hayward, WI | Intesting that your port side is not making contact Bobbie. My port side has a large gap, probably near 1/2" at the widest gap. Starboard would appear to touch at a glance, but looking closely, does not touch either.
The two outer bunks have full contact with the boat, but the two inner bunks do not touch the boat for probably 3 feet in front of the transom.
My concerns are:
1.) I've always thought that a boat's primary support bunks were the middle two
2.) The bunks should come to the very end of the transom to support the transom/weight of motor, etc. properly.
I currently have neither of those two things happening the way they should be. I don't want to develop any stress cracks or issues down the road as I plan to own this boat for a while. The boat is very close to centered on the trailer.
Steve, do you have any more input on this?
Thank you,
Tucker |
