In our members section we have our rules for the ML 45 boat and guidance on building one from scratch to getting it on the water. It is intended as an aid to members building their first boat independently at home between workshop sessions.

The rules fix the hull design and profile below the gunwale line to be strictly in accord with the plans, but allow for the keel and rudder (design only) to be unregulated. With the deck for instance, the option of a cabin, cockpit, canoe fore deck or flat surface are open to design variation, provided the transom and deck sides comply.

Exotic materials such as carbon fibre are not allowed anywhere. The choices for the hull, are timber or fibreglass with aluminium also allowed for the keel. Above deck level, exotic materials for spars, groovy masts etc. are again not allowed. The principal is low cost, easily available, entry level appropriate – a simple low tech boat.

Mylar is now the material of choice for sails, having taken over from coloured Dacron. It's easier making with no sewing and members like it's improved sail efficiency. The result is a fleet of mostly white sails rather than the multi coloured show the fleet used to feature. But, the scene will change, maybe if coloured Mylar becomes an option!

Both the A and B IOM rigs are allowed and members either make them at a club workshop or buy a set from sailmakers we put them in touch with, including members who make them at our workshops or at home to order. Steve Arthur is the external manufacturer of choice members seem to use, having taught the elementary skills at a number of our workshops.

Several members have built 60 inch and 26 inch variants to join the original 30 inch packing case prototype which they sail on special days.
