And yes, bring on the scooter................ sounds good fun, he he he.

easy method grab the shot and go over the side still holding it

Surely they should drop you upline of the shot.....you should only need marginal corrections to the course in order to get onto the shot line.

That won't help with the swim down though

Perhaps borrow some other fins and see if they make a difference......if you find yourself dahhhn sowwwf I have a pair of Mares Avanti Quattro super duper plus that you can borrow.....or I have US Divers Compro (similar to my Jetfins but without the weight).

He he he, think Graham's idea is best - holding the shot as it goes over.

Ta Scuttler for the offer, will take advantage if dawwnnnn sawfff.

Ta guys.

Think I'll get 'em to drop in a shorter shotline too - see if that helps.

If the chance arises get someone to video your finning technique for analysis - the problem could be there. I know a couple of guys who have a 'Troy Tempest' puppet style kick that gives hardly any drive.

Having tried Force fins once they appear to be an aquired taste and gave no thrust for me at all but then I have never been able to get propulsion from 'flutter' kicking while doing crawl so the legs are just stabilisers. If you can't do a 'flutter' kick a la Ian Thorpe you may be better off with a 'regular' style fin. I know people tend to be drawn to equipment 'cos it's 'fashionable' and used by the 'gurus' but that doesn't mean that kit is any good for you. Try out the Scuba Pro split fins, they have a nice 'third gear' kind of feel and are real comfy on the feet.

Good idea, videoing the finning action. I have a video mode on my u/w camera. Will get someone to do it for me.

With the force fins I have lots of finning power when surface swimming on my back but they are pretty poor surface swimming face down.

Perhaps it is the fins after all. I have an old pair of cressie frogs somewhere although I remember that these were a bit on the light side.

Given that I take a large size in Force Fins (due to the width of my drysuit neoprene lined boots) even though my boot size is 5's.........what do you guys think about jetfins/turtles for size and performance?

The video idea is an EXCELLENT thought. In talking to Dave about this project, he also looked at Force Fins (and split fins as recommended above) with a "bicycle" type kick. The different kick did show an improved efficiency in those fins. As a bicycle kick is not a proper or even efficient method, it is not reported in the article above. The paper above was tested with a proper flutter kick. (Another interesting note was that you could improve VO2 efficiency with split fins by using duct tape on the split.)

No 1 Hint for not being knackered going down the shot:

Make sure you're not knackered before you get in. Lots of people are knackered by the time they've finished kitting up in a bouncing RIB. Kit up then sit there for a couple of minutes having a "zen" moment and doing a sanity check on your regs. Then when you get in, you won't be toasted.

do you do any kind of exercise away from diving?

its pretty intense physical exertion when you finning into the current and dropping down a shot.

Excercise? Ummmmmm yes of course.

If the skipper can't drop you in on slack then he should have a shot that you can yank on.
