Handle is for launching in races I guess, it came with 2 but I only put one on - strangely doesn't get in the way at all when paddling. The thing is actually light and narrow enough to be very easy to carry by just hooking your fingers around the edge of the sunken deck, then if its windy I just grab the handle with the other hand holding my paddle to stabilise it - having the handle makes that easy to do and makes you feel that little bit more secure in 25+ knots.
The drain holes are out of the water when you stand, normally your feet are completely dry but if a wave does swamp over the water just pisses out like having a hose on each side - they work very well.
Swept back fin is not standard although I think the Bamboo race fin that comes with the boards (mine is on its way) is actually quite swept back. I like the swept back fin, makes the board more manoeuvrable, for me this board is all about downwind not flat water racing.
PTWoody are you crazy, do you think DJ would put a starfish on his new Javelin

Funny all this fin stuff, I'd bet most people paddling on flat water wouldn't be able to tell what sort of fin was under this board or the Javelin if they just got on without seeing it first.
