trailer bunks position 20SF
 

i have been told different things about trailer bunk position. that bunks should be under the stringers.... my stingers appear to be placed were the hull steps from one strafe to the next, so do the bunks sit under the first outer strafe under stringer or second strafe under stringer. right now mine is set up so the boat cant slide side to side, is this correct? this picture shows bunk location.
thanks.

Since most people have Trim Tabs, Transom mounted Transducers & Saltwater pick-ups within the outer step, generally the bunks are placed inward of the first strake along the stringer as not to interfere when launching or loading the boat from the trailer.

There are many threads with beaucou photos. Use your search feature & take your laptop with you while you soak in the tub!

Did I get this right :rolleyes:

As you sit now, your bunks are not under the stringer. My old trailer was set up like yours.

On my new trailer, I set the bunks on the next panel inboard. Not only are the bunks under the stringer, but the boat centers itself perfectly when loading.

Mine are set as yours are, I can't see bringing them into the narrow strakes and trying to get it to load easily.

Spacing your trailer bunks just outside of and immediately adjacent to the vertical hard-chine of either of the two outer hull panels is good for earlier hulls. This is within 1" of either of the stringer sets on early 4-stringer hulls. Later 2-stringer hulls have the stringer at the middle vertical hard-chine, so the bunk needs to go there on those hulls.

Putting the trailer bunk outside of the chine where it is adjacent to the stringer will give the boat a good chance to self-center as it's being loaded. (This is how my trailer is set up, as seen below).

But the chine must be right up against the bunk to reduce load-induced hull flex and potential cracking.

Putting the bunk directly under the stringer inside of the chine is structurally the best way, but will often result in the inner hull panel falling off the bunk as you drive on, and you end up with your boat tilted to one side and off center. However, this tendency can be easily overcome by what Capt. Chuck and several others did: installing keel-centering bunks on your trailer to center the keel as the boat is being loaded

on mine it has the bunks under the next panel in and i have guide posts as you do and get forward center bunks. it will load straight everytime.
