Mae buddsoddiad Llywodraeth Cymru mewn seilwaith hefyd wedi helpu i ddenu mwy o ymweliadau mordeithio i alw yng Nghymru. Mae hyn yn cynnwys dyfarnu £147,000 trwy’r Cynllun Cymorth Buddsoddi mewn Twristiaeth yn 2017 ar gyfer adeiladu pontŵn tendio arbennig ar gyfer llongau mordeithio a chyfleusterau glanio cysylltiedig yn Harbwr Abergwaun, sydd wedi denu llongau mordeithio mwy i’r porthladd.
Welsh Government investment in infrastructure has also helped to attract more cruise lines to call in Wales. This includes the award of £147,000 through the Tourism Investment Support Scheme in 2017 for the construction of a dedicated cruise passenger tendering pontoon and associated landing facilities at Fishguard Harbour, which has attracted larger cruise ships into the port.
