Having the real benefits of a wide platform is just one of the great advantages of a Multihull.
But ! There comes a time when the craft has to be taken out of the water for whatever reason.
There was a time in Hong Kong when the only place to slip a Catamaran with a beam of 26'3' was at Simon's slipway in SaiKung in the New Territories - just to find the place hidden amongst a fishing fleet was a difficulty of 9 on any Boy Scout's scale. Once there, Simon and his family workers stood at the centre of the rails that led out of the water. From my perspective - My Cat was NOT going to fit !
The Workers ignored me, walking into the water either side of the Cat - then diving - pushing and shoving, then a signal - and the cat was slowly hauled out on her trolley into the shipyard - One of the dirtiest - but most efficient haulouts ever experienced by this cat.
Later, when I needed to work below the water line - used a technique that is easy when a travel lift is too narrow, or when beaching would not work for the purpose. Purchased 2 flat 5" wide nylon slings - each around 20 ft long. Then, if work was required on the port hull - one sling would be slung under the port hull just aft of the bow, and the other would be slung under the port hull just forward of the port transom. Then every movable object secured in the Cat - the Starboard hull kedged off to starboard. Slings attached to Spreader Bar and the yards Crane would lift the port hull sufficiently out of the water for the work to be completed.
