  • 28 dual And tripple trailer first attempt

    I bought the 28’ as a safe family commuter one year ago. One motor had a blown head gasket. Job completed in 3 short days. Ran perfect. Went for a cruise.. good motor died. Thought it was the carb. Nope. Thought it jumped a tooth. Broke the Distrubitor. New Distrubitor hard to find left hand gear bastard. Been moored for a year. Said screw it. Bought an aluminum 20000# trailer today. Bunks gotta be adjust and hope all goes well. Big boat big trailer. Any advice for the bunks so I don’t send the shafts? Pretty critical I’m told. Any trailer bunk advise will help save time at the boat lift and ultimately $$. I know it’s the right trailer, the right boat, but this needs to be perfect. When it’s done she’s gonna be one great setup!

    is the trailer set up for slings?

        Very important if time is an issue with boat yard.You need about 16-18 x 3-4 inches of spacing for slings passing thru the bunks AND they need to be located where the ideal sling location is on the hull.

          Somewhat related... does anyone have the sling location measurements? Or is it a fairly wide rule of thumb type range?

            Mike, depends on your set up. With v drives, mine is best with the stern sling just before the railing walk thru. That still allows clearance to the shafts and catches on the rear of the keel. See attached from my haul out last Monday. With stern drives it might be very different and further aft.

              Awesome thanks, saved that picture. Next time I haul mine I’m considering slinging to trailer rather than dunking it and worrying about getting it centered/scuffing bottom paint with crappy rollers.

                Mike, have you priced Yachtfish Marine’s sling service? They’re pretty proud of that thing!

                    What should I use to give me the 3/4” clearance? Plywood? Then jack up the boat and remove them?

                      to get the slings through, probably need 1 1/2"

                        You will never get slings thru in Seaview Norths yard in Bellingham without jacking up boat. I have two 2x6 (3 clearance) cut outs for slings to be pulled thru. I originally had just one 2x6 (1.5 clearance) and it was very hard to get them thru. Seaview has 1.5 x 14 slings and had to jack my boat up to get them thru. After boat was off trailer I installed another layer of 2x6 boards.

                          I have rear sling cutouts on trailer set to put sling about 6" forward of where shafts exit hull to props. The front cutouts are about 6-10 forward of Glashawks front sling location. I have V-drives as you do.

                              Bill, when I hauled the rear sling was holding ~8000#s and the front was ~3800. So the further fwd towards the bow continues to lighten the front sling load while putting more weight on rear. I’m not saying your location is wrong as every boat is loaded differently. The operator originally had his front sling further fwd and moved it backwards to gain a little more balanced weight...if you can call 32% in the front/68% rear balanced.
