Is the road THAT Bad? Yes it is.
I destroyed two trailers under the 16' Whaler on that drive. One, the carraige let go, and dropped the boat onto the frame - made for a damn slow (5 mph) crawl to the welding shop in Bamfield. The next broke right through at the yoke (where the tongue Y's to the frame) causing the trailer to become a rather effective plow. That occasion, we had to dump the boat in the ditch, toss the trailer into the back of the truck (no small feat in itself!), run it to the same welding shop, and borrow a trailer to fetch the boat. Thankfully it was still there, and thankfully it hadn't been stripped. Oh, BTW, the fella that runs the welding shop KNOWS he's the only game in town, and charges accordingly (I thought he had to be using solid gold welding rods!!)
I will NEVER drag another trailer down that poor excuse for a road! Hard on the trailer, hard on the boat (There IS a reason for the fibreglass repair sign just before you get back to twon) and damn hard on the nerves!! If you MUST drag yours in that road, a couple pieces of advice: Go SLOW!! Expect the run to take a LOT longer than the mileage would suggest! And completely seal off your engine. The road, dispite occasional treatment with calcium chloride, is so dusty it looks like a huge smoke trail from the Inlet. Fine dust particles getting into your engine, intake etc, is a recipe for a severely shortened lifespan!
Yes, the Inlet can be bouncy to run down, not always. Yes, the run is nearly 30 miles. Yes, that eats a fair amount of fuel. But in my mind, running your rig is the MUCH Lesser of the two evils. At least your trailer will in good shape and waiting to receive your boat at the end of your Fun, and your boat won't be needing a visit to the fibreglass doctor (unless you find a deadhead or similiar).
Just this man's experience...
Cheers,
