This webinar is being delivered by Nick Parkyn, who recently delivered a highly successful presentation on HMPE synthetic rigging. Please note the time is UK London.

This time, the subject of Nick’s webinar is Masts, Rigs & Sails, something of a specialism for him. It will be essential viewing for any yacht and small craft marine surveyor whose job it is to inspect and report on such equipment.

His work in the marine industry includes marine surveying, yacht and small craft design and marine software development.
