The ladder should hold up to wave activity. The ladder can flip out of the water to avoid that too.
Yes, but use bolts with washers/nuts, not lag bolts.
I don’t know the actual distance between the steps, but my 3 year old granddaughter has no problem climbing them nor do I. The biggest issue is the first step as to how deep it is in the water.
Yes, but it blends in well with our deck.
We didn’t but we installed it on a wood decked swim dock. My hubs fastened a board down and Then fastened the ladder to the board instead of directly into the decking-it’s not going anywhere!
You need eight 5/16 lag screws or bolts, nuts and washers. Length depends on thickness of deck. Best to use bolts and nuts to go through if you can. Add 1 1/4" to thickness of deck material for overall length
I used 4 inch long 3/8 inch bolts with washers and nuts. I would not recommend using lag bolts. The length of the bolts will depend on where you install them.
From the deck surface to the bottom of the steps is approximately 5ft vertically
We use them at our weekend lake home. No problem for a week or so, but I would not leave them in the water all the time.
