20 Seacraft trailer set-up questions

Ed · #1 08-09-2018, 02:51 PM

I have a customer who is purchasing a trailer for his 20 Seacraft center console. I want to set up the new trailer best as possible in advance before we go on the road for an hour to pick up the boat.

Here are my questions.

1) What is the ideal distance between the rear bunks (two measurements - front end of bunks and read ends of bunks)

2) What is the measurement from the towing eye on the bow to the transom? This will help adjust the winch post to ideal location

2) The forward bunks are self adjusting so probably will not have any much to do there but suggestions are welcome.

Thanks in advance.

Ed, I have been doing a lot of work to trailers for three different SC 20’s. Here is what I have learned;

Question 1. The chines on both outer panels run parallel, so the bunks will run parallel. The distance, and angle cut on top of bunks, will be determined by the width of the chines you decide to lock in. I use the second (middle) chine to butt up against the inside of the bunks, and then the top of bunks are cut full length to the angle of third (outermost) panel of the VDH. This measurement is 53”, and I believe the bevel angle of outer panel is 21 degrees on a table saw for bunk tops.

Question 2. The length from bunk ends to bow roller is 17’ 5”, maybe less three inches to allow for trimtabs. Should get you there.

This pic may be more clear. I have a 2016 Owens and Sons custom trailer, but built for a Pioneer 197, with a wider bottom. But the beauty of this design is the width of the aluminum I-beams are determined by the hull sitting on it. Then the bunks mount full length of the I-beams distributing weight the entire distance of the bunks. In this case, I had to build blocks, not yet mounted or carpeted, to center the hull. These are now 53” apart and will “lock in” the hull from sliding in between the length of the bunks, thanks to the parallel chines (Strakes?) running the entire length of the hull. It’s a beautiful thing.

Thank you very much.
