I now have 90 feet of very high quality rope. A 30 ft 1 1/4 inch with a loop on one end and a huge hook on the other and a 60 foot 3/4 set up with the same loop and hook. I invested in the 60 foot rope after all most losing my rig in the surf when that island was there early summer. 90 feet makes a huge difference.
I think I got stuck 3 times but launched more times than I can remember. I'm launching with an 03 dodge ram 1500 with bald tires. I don't have a ton of experience driving in the sand especially towing a boat as this will be my 4th year running my own dory.
Think upgrading my tires would help? I know tires make a big difference in the snow.
Back on Cape Cod we would run implement (airplane) tires on our rigs.
Traction tires were not even permitted on Cape Cod National Seashore.
The aired down, implement tires do very well in that dry sugar sand back there.
The Pacific coast sand is finer and easier to run on.....seeing passenger cars on the sand (at Cannon Beach) was something that I had never seen before.
So think wide, flotation, aired down and not so much on the aggressive tread for sand.
