Put a limit on Trip: Load Dimensions as well as Trailer Specs.

For The Trip: Load Dimensions you only need one record per Trip Load. It is your Load size.

For Trailer Specs it only needs one record per trailer as well.

I had only one record for Boat Conditions but I removed it. That is because you need Boat Condition form filled out for each boat you have on the load. Sometimes like the load I am under now, I have 3 Boats and they are in bad conditions.
