The original GBE was designed by the late Malcolm Tennent as a fast day sailer/ weekender with minimal accommodation in each hull
and weighing less than 1,000kg. I used to own the hull
moulds for the GBE, but sold them about 18 months ago.
The Sportsdeck was the same hull, but extended one foot, and with a bridgedeck, double berths and a small open cabin
, weight increased to about 2,500kg and the rig reduced in size. As a result the once sporty cat became a lot slower and sitting lower in the water
as most owners started to fill the it with fridges, water tanks
and all other bits of cruising equipment
, all in a hull that was not designed for these loads.
I believe they were all built with polyesther resign below the waterline and a lot have had osmosis
problems, my son who is a boat builder
has been involved in repairing damage to GBE Sportdecks.
I have raced against 'Queenslander', the first Sportdeck built, and have raced on other Sportdecks built since, but found them a bit slow.
