ParticipantHello all,
Blue Moon comes out of the water Oct 3, and I have some concern regarding the process. Mainly, I don’t know if the mizzen mast will need to be removed. Looking at the diagram in the owners manual, the aft strapping point is located just forward of the mizzen mast. I need to look at the travel lift yet, and maybe there is vertical clearance, but I don’t know, but I do know the boat yard has some concern. I will take the diagram from the owners manual down there in the next day or so, but thought I would ask the group if any of you have any advice to offer beforehand. Thanks…
David

ParticipantIve taken mine down for about twenty seasons but I’m not sure. I think it has to do with the center of gravity in the slings.Yours for a better world

ParticipantDavid,A lot depends on the size of the Travel Lift. On large ones I can pull in bow first and there is enough clearance for the head stay. On normal size lifts I back in and loosen the running backstays and the topping lift on the mizzen. No problems that way.The big concern is the location of the aft sling such that it does not catch the prop or the shaft. Usually I make sure the sling is not forward of the mizzen mast. There is a lifting diagram somewhere on the P424 website you should provide to the yard. -

ParticipantNormally, my club removes sloops from the aft end, requiring that the backstay be removed. Ketches however have the mizzen in the way so we remove them bow-first. The forestay must be removed and pulled back out of the way. This is a PIA since the roller furling extrusion is inflexible and hard to move around. Thatâs why we prefer to do sloops stern first.
Slings on the 424 must clear the prop and strut. For me, thatâs right at the primary winches. The yard snugs up the straps then I go below and spin the prop shaft to make sure itâs clear of the straps before they lift. The straps are positioned as far apart as possible with our 50-ton travel lift.

Participantmake sure you make the prop spin before they lift it out of the water!!

ParticipantI have had my ketch pulled a few times – I always bring a profile showing the strap locations for the yard. The only thing I’ve ever had to do was to loosen up significantly the sheet back stay lines for the mizzon- no mast pulls, not a big deal – usually bow in.Joe Shimkonis

ParticipantI’ve never had a problem. Just make sure the aft strap isn’t on the prop shaft. The first time my yard did a lift, they had a guy dive under to check placement. Then they took pix for future reference.Dan KJolly Lama #135Keehi Lagoon, O’ahu -

ParticipantGood inputs from everyone. Thank you!! I have the âdocking planâ from the owners manual, that shows strap positions. Good idea aligning them with the primary winches for simplicity. And spinning the prop shaft by hand to ensure it is not snared. I think I will have my mask and snorkel on hand as well. Theyâve asked me to pull in bow first for whatever thatâs worth. Sure donât want to pull the forestay and risk dinging up my purty new deck paint!

ParticipantDavid,
Yards sometimes want us to come in bow first – it just happened to me last week – but I won’t do that. Give them a copy of the Pearson 424 lifting strap profile. Then back in and move the mizzen running backstays and topping lift forward to the mizzen mast, out of the way, so they can position the travelift crossbar about 3-inches abaft of the mizzen mast. The straps then go exactly as shown in the lifting strap profile from Pearson, which means the aft strap aligns with the forward edge of the mizzen mast. Spinning the prop shaft before they lift is a wise precaution, but if the strap is aligned with the mizzen mast’s forward edge it’ll be right.
What you should be asking now is how to block up the boat once it has been hauled out.
Have fun,
Tor

ParticipantThanks Tor, good poop. Should be interesting, a lot of good inputs. And OK, Iâll bite. Any suggestions on how to block up? I already know to drop her hard on a block on the aft end of the keel (not!! Good discussion on that topic lately).

ParticipantIn the 9 years we’ve owned our ketch, we’ve only been going to one yard here on O’ahu for service (only 2 big Travelifts on island). We’ve always gone in bow first and never had to adjust the rig. Based on all the more experienced comments posted, I’m wondering if this is uncommon?DanJolly Lama #135KeehiLagoon, O’ahu -

Participant“I'm wondering if this is uncommon?”Dan,Most travel lifts are not long enough to raise a sailboat bow first without the head stay hitting the cross bar at the top of the lift. Yards that service multihulls and large motor yachts may have a travel lift that is long enough for a bow in lift. The yard I used for years in MD have both types of lifts, but they preferred to lift me with the smaller lift. So I always went stern in. They told me the smaller lift balanced my boat better, but I think they just wanted to save wear and tear on the very expensive lift that they used to haul much more profitable boats than mine. -

ParticipantWith Pearson 424 ketch Mary Murray, I slacken the mizzen backstays so I can release the roller forestay. Roller forestay is then strapped a beam of main mast on toe rail. She then goes onto the travel lift bow first. My Pearson owner’s manual shows position for the straps and that has been well covered in previous correspondence, I have now marked the position on the toe rail. I like the idea of rotating the prop shaft. I usually put on mask and snorkel and check, OK in Tyrrel Bay but not so pleasant in Rodney Bay !! The bow strap can crush the impeller on the log so I carry a few spares.CheersMark

ParticipantMark,
I hauled out in Tyrell Bay 8 days ago – stern first, although they at first wanted me to undo the headstay and go that way. Despite my assurance that the aft strap aligned with the mizzen mast’s leading edge was correct, they sent a diver in anyway to be sure it missed the prop shaft. Excellent yard manager & crew there.

ParticipantHey Dan,
As the saying goes, it’s nice work if you can get it. Really big travelifts can lift a 424 either way without having to slack any rigging. 50- and 25-ton lifts, however, cannot. You have to undo either the head stay or the running backstays (on a ketch). The latter option is just a whole lot easier.

ParticipantThanks all for the info on lifts.Never really thought about the variances as we go to the the same local yard all the time. All our sailing with this boat has been limited to these Sandwich Isles.Dan KJolly Lama #135Keehi Lagoon, O’ahu
