recently i was in augusta in south west WA, and i took out a windrush 14
it bloody thunders along, i had three of my mates in it and we were getting up on one ull with us all out hiking
just wondering what is the protocol for tacking, ie sail trimming, weight trimming and helming technique
we worked out after 2 days if the two crew slide down to the leeward hull as i let the weather helm carry the boat into the tack and when speed runs out, i jam the tiller over, we then let the jib back and continue to take us through the tack.
the problem is we go from 9-12 knots then stop completely in the tack and then when all the mainsail battens pop back into shape(which i must say is entertaining, they pop from the bottom up) then the boat accelerates again.
I haven't been able to watch anyone else manouvre upwind in a windrush or hobie and im sure some people have some valuable knowledge to share
regards

3 people is probably too much to start with.
But , it comes down to using the mast/sail to rotate the hull.
the centreboard less parallel hulls dont want to turn, so you need to use bodyweight/sheeting .
practice sailng along whilt moving your body weight fore and aft to see how it affects the load on the tiller. with practice you will be able to sai without the tiller.
Then practice making the yacht round quickly to windward using bodyweight and a light tiller

easy as mate, windrush 14 is generaly a one person cat for starters, when sailing to windward keep the boat balanced as stated in the previous posting. Keep mainsheet cleated on before tack so you go into the turn with max power, transfer your weight mid tack and as you go under the boom uncleat the main and ease the sheet a little and pass the tiller around when you hear the main kick in gently increase main tension, hope this will help

set up a trapeze, get yourself a harness, extend the tiller length and let the fun begin. they r still a one man boat, even with the jib they are known as a super sloop windrush 14. you need your weight out on the trapeze for more leverage so as to keep the boat flat and balanced, flying a hull is fun but its not always the fastest way to sail a cat.

they are raced with one or two people.

cat rigged (mainsail only) is generally sailed by one person
sloop rigged (mainsail and jib) is often sailed by two people
super sloop (mainsail,jib and trapeze) sailed by one person on trapeze

the hire cats in south perth are windrush 14's and are surveyed to carry up to three people.

Thats probably because there is so much weight on board ,all the forward momentum is lost on driving into the water. like trying to sail a landyacht with half flat tyres. you still heel and feel like its powering but youre not going anywhere

Hey Nathan.
I used to Race windrushes and they are a very powerfull boat and very fast and wet and all the great things about sailing.
They are also very hard to tack but once you get it you can chuck em around too easy. I used to sail with a Jib and by myself (super sloop is the configuration) Basically to tack you have to be going as fast as possible close to the wind. You shift your weight aft just prior to the tack.
Screw it around reasonably violently let the main right off and change sides. The jib will back and leave it back for a extra second or 2 (longer for lighter winds) and the boat might start to go backwards. If is does go backwards reverse your rudders like a 3 point turn. Change the jib and pull the main in a little as the boat starts to move off and once you gain positive steering crank it on and your off.
If you have trapeze(essential for maximum fun) jump out as you crank it on and the boat will fly of in a ball of spray.
If you crank the main on too early the boat will screw itself into the wind and you will be stuck in irons.
I think your local to me (rockingham) so when your taking it out next I can come down or come down to one of the winter series heats or definitly the cat classic and I can help along with a dozen others who love to give out advice ha ha

The cat classic is great there will be all sorts of cats there and we all race against yardstick which brings all the boats back togethe irrespective of speed and Windrushes typically perform very well on yardstck especialy in the lighter stuff which the cat classic is normally. If you want some tips and some practice b4 the season let me know

hey mate
with regards to improving your tacking its mostly the sail trim

weight is less important but keep it foward so as not to stall or go over backwards if its howeling, wire to wire if you can

main in tight (this moves the center of effort fowards to help the boat turn up into the wind)

nice controled turn into the wind again to stop the stall

as soon as the jib backs leave it for a second or two to help it pass through the eye of the wind and then at the same time release the main to move the center of effort fowards and finish the tack

once the batterns in the main have popped onto the new side slowley ease back in with the main to fast and you will stall the air flow

hope this is some help

hey .....
i sail a hobie 16 by my self all the time only useing mail and jib with a trapeze ...
i would bear away a iny bit 2 pick up a bit of speed ..... id drop the tiller round back of boat ... run forward uncleet the jib ... pull main on hard to force into wind grab the tiller and full lock to pull it into the wind also haveing ur body weight fully back to shorten the water line lengh ....... making the back sink and nose go up in the air means a short water line and a sharper turning circle as soon as the jib is pushed on the other side of mast ( gone thru the wind ) i would let main go and pull new jib lead on tight and putt body weight forward to help pull bow around .... id then hook up to trap line grab main and tiller then accelerate
i can leave the tack with still forward momentum ..... in light wind keep the jib back winded for a lil bit longer ..... or some times realy tight jybes ....
