Default Boat Lift Bunks for Stepped Hulls

Not sure if this is the right forum to post this but here goes...

I need a new boat lift and was wondering if you guys with stepped hulls choose to modify the traditional carpet covered wood bunks to support the boat off of the edge of the steps or do you choose the individual chocks to support the boats. New lift is a 16k lb lift from either Golden or Deco. The full length aluminum bunks don't really look like they will work since they can't be easily modified. Looking at either full length wood or aluminum chocks.

Thanks in advance.

Try MYCO Trailers. They built bunks for lifts at one time.

MIKE! How you doing man!?

Can you affix strips of wood to the top of the aluminum bunks? Most folks just add strips of 2x4s (adjusted thickness if necessary) to the top of the long bunks.

Recessed lag bolts hold 5ft 2x4 on the rear of my hydro hoist . Carpeted over them once through bolted.
Need a pic of your bunks

Myco builds awesome cradles but they are very expensive. If you are on a budget like me I built new bunks using double 2 x 10's screwed together with stainless steel deck screws. I then added steps by stacking wood and some composite material on top to get the correct lift per step. Some new carpet and it all gets covered up. This was for a Donzi 35 ZF.

I am in the process of doing this right now and I have the same plan mentioned earlier for my Donzi 35 ZR. My lift bunks are 2x6s. Going to buy treated 2x6s, cut them down to size and stack to support the furthest back step. Then I'll screw them together with stainless deck screws and carpet them.

Just remember to give yourself some wiggle room by holding the steps on the lift back from the actual steps on the boat, a 6" to 1' gap aft of the step is okay and better than getting too close and risking catching the edge of the step with the bunk. So many lifted step boats have chips in the trailing edge of the steps due to it hitting the higher bunks behind it. .

I know I posted this before - never did get a response

Has anyone tried any of these plastic strips as bunks - no carpet just long pieces composite plastic in the dimensions of a 2x6-- (I'm guessing on the size)

Pro's and Con's

Thank you

When my buddy built his 38 powerplay he brought lumber to Dan and had the lift bunks cut to fit the step bottom so it was a perfect fit. When he sold the boat he gave buyer the bunks off his lift.

I'd actually cut them diagonally, in the opposite direction of the boat. That way if the boat is near the edge of the step portion of the bunk, it will want to slide forward, down off the slope of the higher area of the bunk.
