I think that will be a custom job from a local stainless man. I've not seen and "off the shelf" solutions.

If you drop me your email I'll send you some photos of what we added on our 461.  It was nicely crafted in Spain in 35mm stainless and incorporated all sorts of little features which has made using the boat much easier.

this davit was made in Marseille. It is constructed with 48mm tubing. Balcony's are incorporated into the davit. At one end a lifting apparatuss was installed wich we tested with 400 pounds. It is strong enough to lift a men in a wet mustang ( flotation device for waters at 0 degree. The top part has been prepared for solar panels that exceed 3.4 meters 2X 240 watts ( solar modules ) that will be installed off season. The plates that I had installed to lift the dinghy are made of 1/2 inch stainless steel . To lift the dinghy triple blocks where installed at both ends. The dinghy is AB aluminum with 20 horse 4 cycle. Hands where constructed at the base of the arch wich are on the edge of the boat. 3/4 inch screws where adapted with plates installed in the outside locker as well as in the two back cabins. Inside each tube we left runners made of stainless steel to further run any apparatuss on the arch. At the base of the back tubes are holes of 35mm to run the wires. We did not do this in the front tube since there is no lead possible in the cabins. The futur solar panels will be forwarded to a second pack of battery wich will be positionned on the port side of the saloon since the boat is already to heavy on starbord. With a reserve of 940 amps the boat shouldn't have to charge with the gen everyday. The main reason we chose the 48mm tube is that on a very rainy day if ever the drain of the dinghy clogs up chances are that the arch will not bend. We have not stressed the arch to see the brake point , but we did put 300 kilos just to see and no sign of weekness. Hope this info was usefull. Each arch are made individualy. But for the 470 the measures are made and one could order and have it delivered.

We make for HANSE 470 such a variant of the solar battery power of 1 KB per hour. The construction is made of aluminum and has 20 solar panels.

Also available are designs for other yacht models.

Hello Jean

Thank you for sharing your gantry picture.  How has it worked with the solar panels?
We have come to the conclusion that a gantry is the way to go to make solar work well, and tidy up all the bits of kit that are bolted on to the back of the boat.

Would you be willing to share more details, like pictures, plans feedback on what you would do differently is starting again?  That would be much appreciated.

Thanks, George.

we had a custom arch and hardtop designed and built in Fort Lauderdale this past year on our 461, I’m happy to share our experience with designing it. She holds 2,000 watts of solar and offerst fantastic shade over the cockpit  s

Howie, that is an awesome hardtop.  Could you share some information about the construction, cost and how it's holding up?

I like this arch very much. It looks very reinforced.
We have the boat in Barcelona (Spain) 
You have more images 
Thank you very much

Hi Nirvana - while stern arches can be really useful (I have one) do keep in mind that you're placing a heavy weight in the second-worst place onboard.  This will affect performance to some extent and can cause the boat to hobby-horse (go up and down instead of forward) in waves.  While your 461/470 can certainly tolerate more weight on the stern than my 400 you still have to be careful not to overdo it; dinghys, engines, life-rafts mounted on the stern all have an effect and you can turn an easily-driven hull into a right pig if you overdo it.  I'm not saying that this is necessarily wrong; everything on a boat is a compromise and its up to the owner to decide what is acceptable for that person's type of cruising.  What might be unacceptable for offshore or ocean sailing might be perfectly fine if you mainly sail in the right conditions.

I don't think you'll find a ready-made arch from any supplier; you'll need to have one built specially for your boat.  These can be very expensive; mine cost the equivalent of EUR13000 a year ago and even though its been useful I still question the value for money. Whatever, keep in mind that even a brilliant stainless-steel fabricator is unlikely to be a sailor and will care little about balance on a sailboat.  The pitch axis is about a meter or so forward of the sprayhood (dodger) so the further the distance from that point the more that added weight will affect your boat. 

Looking back I might have chosen aluminum instead - but of course it doesn't look as nice as stainless!  However, despite keeping the design fairly minimal I noticed a clear hit to boat trim and windward performance as the boat 'sat' heavier in the water at the stern, something that can clearly be seen in one of the pictures in an earlier post above.  To compensate, I got rid of a lot of weight and moved heavier items as close to the pitch axis as possible.  This included moving the tender from the locker to under the boom and replacing a very heavy life raft with a lighter coastal version (although I hire an ocean one when heading beyond easy SAR coverage).  These are all compromises I chose for my boat for my type of sailing but I'm sure that many others will make different choices.  Just don't think that putting an arch up is a 'cost free' alteration - in any sense of the phrase!
