As mentioned in another thread (https://www.myhanse.com/engine-overload_topic11838.html), I may need to dry out High Time either at the local Sea Lift facility or against some local piles.

My question is has anyone successfully dried out a 415? If so, were there any problems?

I have heard stories that the weight distribution and keel position on the old 400 meant that it could come to rest on the rudder as well as the keel which is obviously not good for the rudder. Is this true for the 415 or does good balance for instance depend on keeping the water tank full and the fuel tank empty?

I would obviously like to know it works OK before I try it!

Hi Roger, don't know if i would try it out. The inner reinforcement frame is glued to the hull, not really bonded ( you can discuss about this ) and this works perfect to carry the heavy keel. The opposite way the force is pushing it up and there i do not feel comfortable. There are several cases know, after a grounding , the frame looses from the hull ( gets ripped off ). Our 385 is standing ashore and yes most of the force comes to the keel, fair enough, and this is OK but when drying out you cannot guarantee the keel will not hit the bottom several times, sometimes by the waves and sometimes by over enthusiastic boaters who pass.  This is for me the fear factor why i personally would not consider this. 

good luck ,
Best regards

Umm. I understand what you are saying; bouncing on the bottom could be a problem. It must be 20 years since I last dried out on the piles and that was on a medium fin Moody 346. It was OK but I do remeber the last half hour before she settled was a little nerve wracking.

I wonder if anyone has tried a 415 on the SeaLift (http://www.sealift3.com)? That looks like the best option. Maybe get a quick coat of antifouling done at the same time!

I would not dry out with full weight and load on the keel, you will be amazed how much our hulls flex and sag on the keel. 

Up until 415/455 generation keel to hull joint was faired with filler to a nice shape and profile. Hanse dealers stopped doing this and instead just do bead of sealant because when boat was on the cradle and fairing all nice it then cracked badly once picked up by the hoist as hull flexed up and away from the keel. 

Far to much stress on inner grid structure in my view.

Hi, we have taken Night Train out the water twice. Once by a travel lift and once with a large hydraulic trolley. Of the two methods I prefer the latter as it supports the weight of the boat on both the keel and about 8 hydraulic pads that are raised before the boat comes out the water. 
With the travel lift the straps tend to impart a sideways force on the hull. Asian health and safety allowed me to be on the boat during lifting and it was noticeable that the companionway hatch wouldn’t open until the boat was lowered down.  
Neither option was cheap, couldn’t you employ a diver first?
Good luck
Paul
