Its not the same as property share as you are a part owner of the boat, usually a 12th or similar. Most syndicates have around 12 owners and you generally get 4 weeks a year (often more if anyone cant do their time). Allocation of the weeks is the bit that varies between syndicates, some have a random hat, others have a list, some have red/yellow zones etc... You purchase your share, then pay a monthly fee for running of the boat - all of this is free to see on share websites such as www.bcbm.co.uk etc... its a great way to cruise the network as the boats move around bases over time following AGM votes etc.
