1. Truckers Hitch AKA Movers knots.
Use this all the time when securing loads to a moving dolly
2. Bowline
The most useful knot
3. Half Hitch
Very useful
4. Halyard Hitch
Sailed for years and never used it. Always spliced in a snap shackle
5. Square Knot
Not the best knot to bend to lines together. I only used as a reef knot
6. Add carrick bend
7. Tugboat Bowline if you need an instant bowline
reviewing your comments for each and understand each of them. Having worked for a long while as a vessel commander. I had not seen or read anything in RV forums about Knots (which I find most useful. So I was suggesting 5-knots for campers to learn.
True about number 4-Halyard Hitch, when correctly used unlike the Bowline can be used when attaching a line/rope to a vehicle's tow hitch, or vehicle Marine U-Bolt anchors, when correctly used makes a strong knot for holding onto metal clits for pulling stuff. Also inside of a trailer to prevent load shifts. as for the suggestion of the "snap shackle," it creates a loop thereby putting the pulling force on the sides of the rope and knots weak areas. The Halyard Hitch can be used closer to the metal hook, anchor thereby less weak spots and on the ability and strength of the rope and not the knot. You are also correct and I often use the "carrick bend" but for a new person to learn them they need to be simple instructive steps. The square knot can in most cases to do the job if by joining a broken line, joining lines for add length. Here I was just trying to keep the newbie rope handler interested, and fun. Keeping someone engaged in completing the task needs to have built-in success for accomplishments and easy recall. Harder and more complicated knots will come over time.
One last point RV'ers unlike boates in almost all cases never need to tie a fast knot. Understand I'm trying to keep them useful, interesting, fun with easy recall when needed. Unlike a boater who may need the same knot 5- or 10 times in a day. Where the RV'er may use once a year.
I'm sure there are lots of good easy knots one can learn as we have over time. I just wanted to show 5-basic knots for the RV camper and there loads. But anything is better than nothing.
One story I'll share I once owned a JEEP Commander fully trail Rated for off-road use. (this means that under the vehicle are protective plates to protect the undercarriage) Diving down a highway some mover with an open trailer had a pillow fly off his trailer onto the roadway. It was about 18" by 18" and YES I hit the pillow and it stopped me dead. On closer examination, the pillow had attached itself onto a two-part cable ripping them off the JEEP. Overtime messed up unknowingly my NEW transmission. I will never own another JEEP after that learning curve.
If the guy had known something about knots it may never have happened.
I truly enjoyed your feedback and hope my reply was clear. I truly did like your insights.
