As far back as 2009, I was tal­king about sustainability in the nau­ti­cal world and pre­dic­ting ra­pid pro­gress from bo­th de­si­gners and yards in terms of re­du­cing the impact of ya­ch­ts on our eco­sy­stem. Over the in­ter­ve­ning se­ven years, im­pres­si­ve re­sul­ts ha­ve been achie­ved: wa­ter­li­nes ha­ve been ma­de mu­ch mo­re ef­fi­cient, clien­ts ha­ve shif­ted their al­lian­ce en mass away from pla­ning and to­wards di­spla­ce­ment ya­ch­ts whi­le all on­board au­xi­lia­ry sy­stems aboard al­so now run off mu­ch mo­re ef­fec­ti­ve ge­ne­ra­tors and electric mo­tors. All in all, great stri­des for­ward ha­ve been ma­de – we are now sa­ving around 40% mo­re energy sim­ply by op­ti­mi­sing tra­di­tio­nal sy­stems th­rou­gh a de­si­re to focus mo­re ably on re­du­cing our impact on the world around us. Ve­ry new tech­no­lo­gies, su­ch as so­lar pa­nels, fuel cells, wind tur­bi­nes and so for­th, ho­we­ver, still ha­ve not be­co­me ef­fi­cient enou­gh to pro­ve tru­ly sa­ti­sfac­to­ry. We’ll ha­ve to wait se­ve­ral mo­re years for that to be the ca­se. At the end of the 1960s, a na­tio­n­wi­de law was in­tro­du­ced that pro­hi­bi­ted the di­rect dum­ping of do­me­stic wa­ste in the sea and we all in­stan­tly no­ti­ced an enor­mous dif­fe­ren­ce. The my­riad pla­stic sacks of rub­bi­sh pro­du­ced aboard boa­ts (and in coa­stal ho­mes!) sud­den­ly va­ni­shed! Al­thou­gh we still clear­ly ha­ve a pla­stic bot­tle pro­blem, I do think that 90% of the­se co­me from the coa­st in ge­ne­ral and bea­ches in par­ti­cu­lar. It is de­pres­sing to see the sta­te that bea­ches, whi­ch ha­ve been ma­de off limits to boa­ts be­cau­se of they are con­si­de­red pol­lu­ting, are left in by the ho­li­day-ma­kers that ha­ve co­me the­re from in­land. Bot­tles, cans, tins, card­board con­tai­ners, all ju­st aban­do­ned by ill-man­ne­red vi­si­tors to our gor­geous bea­ches. This con­ti­nues to hap­pen in Ita­ly whi­le other na­tions ha­ve seen the pro­blem and do­ne something about it. So plea­se: a lit­tle mo­re focus on bea­ch-to-sea pol­lu­tion ra­ther than boat-to-bea­ch pol­lu­tion! The po­li­ti­cal drift is tur­ning this rea­so­ning on its head and it has to stop! 146 Già nel 2009 ave­vo espres­so il mio pen­sie­ro sul­la eco­so­ste­ni­bi­li­tà nel mon­do nau­ti­co pre­ve­den­do una ra­pi­da evo­lu­zio­ne da par­te di pro­get­ti­sti e can­tie­ri per ot­te­ne­re un mi­nor im­pat­to de­gli ya­cht sul no­stro eco si­ste­ma. In que­sti set­te an­ni so­no sta­ti ot­te­nu­ti ri­sul­ta­ti im­por­tan­ti: dal­le li­nee d’ac­qua del­le bar­che che so­no di­ven­ta­te mol­to più ef­fi­cien­ti, al­la scel­ta com­mer­cia­le dei clien­ti che si so­no spo­sta­ti in mas­sa ver­so mo­tor ya­cht di­slo­can­ti e non pla­nan­ti, fi­no a tut­ti i si­ste­mi au­si­lia­ri che uti­liz­za­no ge­ne­ra­to­ri e mo­to­ri elet­tri­ci mol­to più ef­fi­cien­ti. Ad og­gi quin­di si so­no fat­ti gran­di pas­si avan­ti, ar­ri­van­do a cir­ca il 40% di ri­spar­mio ener­ge­ti­co, so­lo ot­ti­miz­zan­do i si­ste­mi tra­di­zio­na­li fo­ca­liz­zan­do­si di più e me­glio sull’obiet­ti­vo del­la ri­du­zio­ne dell’im­pat­to eco­lo­gi­co. Le nuo­vis­si­me tec­no­lo­gie, co­me i pan­nel­li so­la­ri, le fuel-cells, i ge­ne­ra­to­ri eo­li­ci e via di­cen­do, non han­no an­co­ra rag­giun­to un li­vel­lo di ef­fi­cien­za ta­le da po­ter es­se­re ap­pli­ca­ti con sod­di­sfa­zio­ne. Do­vre­mo aspet­ta­re an­co­ra di­ver­si an­ni. Al­la fi­ne de­gli an­ni ‘60 era sta­ta in­tro­dot­ta una leg­ge sta­ta­le che vie­ta­va lo sca­ri­co di­ret­to dei ri­fiu­ti do­me­sti­ci in ma­re e im­me­dia­ta­men­te ci si ac­cor­se del­la enor­me dif­fe­ren­za: scom­par­ve­ro le mi­ria­di di sac­chet­ti gal­leg­gian­ti pie­ni dei ri­fiu­ti pro­dot­ti dal­le im­bar­ca­zio­ni (ma an­che da­gli abi­tan­ti del­le co­ste!). Ben­ché si sof­fra an­co­ra del­la pre­sen­za di bot­ti­glie di pla­sti­ca gal­leg­gian­ti, cre­do di po­ter af­fer­ma­re che il 90% di que­ste pro­ven­go­no ap­pun­to dal­la co­sta e in gran par­te dal­le spiag­ge. E’ tri­ste ve­de­re co­me a fi­ne gior­na­ta le spiag­ge, che so­no sta­te vie­ta­te al­le bar­che per mo­ti­vi di in­qui­na­men­to, ven­ga­no la­scia­te dai ba­gnan­ti ar­ri­va­ti via terra. Bot­ti­glie, lat­ti­ne, sca­to­let­te, tu­bi, car­tac­ce, tut­te ab­ban­do­na­te da que­sti ma­le­du­ca­ti tu­ri­sti bal­nea­ri del­le no­stre stu­pen­de spiag­ge. E an­co­ra una vol­ta que­sto ac­ca­de in Ita­lia men­tre ne­gli al­tri pae­si c’è già sta­ta que­sta pre­sa di co­scien­za. Quin­di at­ten­zio­ne all’in­qui­na­men­to ge­ne­ra­to dal­le spiag­ge ver­so il ma­re e non dal­le bar­che ver­so le spiag­ge! La de­ri­va po­li­ti­ca do­vreb­be smet­ter­la di ro­ve­scia­re le real­tà!
