For the Larger beginner

The OK carries weight very well, sailors being competitive over 100kg.

The boom looks low while sailing, but while tacking or gybing the boom comes up as the rig straigtens, and if you get a tape measure there is actually more space under it than in a laser, due to the deep cockpit. Plus if you are a heavier sailor you will not have as much rake on the mast which will mean the boom will come up even higher with no mainsheet tension on.

Just remember, no kicker upwind, use mainsheet for leech tension and traveler for setting boom position. Dont forget to let the kicker off downwind for the gybes! It only takes 2 or 3 dunkings from forgetting this, to get the hang of it. The rig is very similar to a europe or fin,  it is a very rewarding boat, doesnt require the fitness a fin does and carries weight unlike the europe.
