Bigger Sister to Oppikat Catamaran

Following on my last post, about the new build options for the Oppikat, a customer has commissioned a bigger sister. Over the years many people have asked if we had a bigger cat for them to build. They wanted a boat that could be sailed by two adults rather than by children or by one adult with a small child. So, now we have the Bigakat 12. The first boat will be built in Nassau, Bahamas, from plans and patterns. The drawings have been completed and are already on their way to the amateur builder.

The Bigakat 12 is in every respect a bigger sister to the Oppikat. The build methods are the same, with plywood upper hull panels and strip cedar below, over plywood bulkheads. Only the size and proportions have changed and some minor details.

While working on this project I took the extra time to add more drawings to the set than we have in the Oppikat design. The additional detailing helps builders to better understand the construction details and process of assembly. Better understanding improves confidence and building speed.

Biggakat 12 sail plan.

Specifications of the Bigakat 12 are:-

LOA - 3.72m (12'2")
LWL - 3.72m (12'2")
Beam - 2.10m (6'10")
Draft - 0.27m (10.5")
Mainsail - 7.83sq.m (84sq.ft)
Jib - 2.5sq.m (27sq.ft)

The standard plan package for the Bigakat 12 includes full-size patterns for all bulkheads, printed overlaid on top of each other. As an optional extra we can also supply full-size patterns on paper for the bulkheads each set out separately, along with patterns for the plywood panels of hull and deck. This allows the builder to cut out the bulkhead shapes to paste them onto plywood for cutting.

We also have detailing to build the Bigakat 12 in fibreglass, laminated in female moulds. This version is primarily for pro boatbuilders to build in series. We don't currently have any GRP builders producing the Oppikat and Bigakat 12 but would be interested in discussing this with any pro boatbuilder who is interested.

Plans for this design and all of our other designs can be ordered from our desktop pricelist or our mobile pricelist.
