Nicely rendered.
I wont comment on the styling, at these bespoke build size breaks the client will be the final judge.
I'm not convinced that the internal layouts could ever match the levels and heights suggested by the exterior glazing.
Be prepared to have to reduce the extremely generous headroom heights you have made such a feature of....the 80m for example looks like another deck level could be slotted in there
....whilst impressive, excessive headroom is expensive, in terms of wasted accommodation space, wasted gross tonnage volume, wasted air-con / heating, very heavy glazing (plus extremely onerous rules that accompany such large glazing) and also wasted stability. Height will adversely affect stability through the overall VCG. Its easy to envisage a three deck yacht thats 10m high, having far better VCG than the same three deck layout stretched upward to 15m high ? A point that any eventual NA will point out very early on if the projects ever progress.
Maintenance....the client may go for the concepts, but his crew will be cursing you for creating what would be a nightmare when it comes to up-keep. Vertical cliffs of external superstructure, football field sized superstructure roofs with no visible means of (safe) access, acres of teak decking, acres of glass...how would the crew clean these areas daily ? (twice daily in port
) Yachts with full beam accommodation fwd are bad enough, but you have taken the practicality of exterior cleaning to sky-scraper levels of logistics.
Patio doors...very high, very angled patio doors have a basic design flaw...I'll let you use your head to work it out
Large external glazing...good luck when it comes to getting the glazing passed by say, RINA.....I'll take a stab at a final requirement of 150mm thick laminated plus storm shutters on the 60m concept fwd hull glazing.
Deck space....the 80m is something else, even the best interior designers (yes they will be asked to design the external space layouts too) will have a mission to utilise such wide open spaces sensibly and practically. If current trends continue, dont be upset if your concept becomes a sea of sunbrellas / parasols / awnings etc, or the client pushes you to add another enclosed superstructure up top...which brings me back to height and stability.
