"...seat time ..."
That's the most difficult time to acquire at sea.
Pendennis Shipyard has been running an apprentice programme for all trades since 98, it has been a huge success for both the young people in Cornwall and the Shipyard itself. Well over 100 Apprentices have been through the system and as far as I know, every one of the boys and girls that completed the 4 year course, so far has been offered full time work in the Shipyard. Plenty have then crossed over to work on yachts and some have been poached by other firms! I know all the trade managers onsite would agree it is an asset to have young people who have been specifically trained in the way of the Superyacht , I also understand apprentices past and present make up about 10% of the 360 strong work force on the yard up to a Management level. This scheme has won the UK’s top award 2 years in a row bust most importantly I know this type of scheme also goes on in yards from Holland to NZ to the USA so whatever country you are from get in contact with the Shipyards and give it a shot. As people have mentioned in previous posts on this site, crews do change when boats are in refit and obviously plenty are taken on during builds, so in certain cases what better place to be? Good luck. TR.
