Boat lift bunks

[NAM75]

I take my Response to my parents lake 3-4 times a year.... weekend and 1 week of vacation...pretty busy with wake boats.

I used to tie up to the dock with bumpers.... but a neighbor had a boat lift for cheap!

It is in good condition, but the bunks are vertical 2x10. They are adjustable width wise. Is this ok? 

Most other lifts I’ve seen have the bunks horizontal... like a trailer.

I guess I could add a set of vertical bunks and end up with 4” width?

Thanks Crew!

Most bunks are 2x6 on the flat.  I would put a 2x6 atop (perpendicular) the 2x10.

Lots of people double up 2x10’s and have no issues.

Only issue with doubling up the 2x10’s I see, is the lack of flexibility. The 2x6’s on my lift flex/bow enough to nicely follow the contours on my hull when boat is lifted up. I would be worried of pressure spots causing damage to the hull having doubled up 2x10’s.

I would remove the old 2x10 bunks all together and get some PT 2x6’s, cover them with bunk carpet (on the cheap available at eBay) and mount these instead.

I completely agree with this.  Also, measure your spacing on the trailer bunks and match that with the hoist.  Then confirm that the measurements are consistent with where the stringers are located in the engine chassis system.  After that, you're good to go.

I've been using vertical 2x6's on my lift for 6-7 yrs with no issues. Covered in carpet of coarse.
