Below is a recent sunset at Lake Newell, Alberta.  A sight that hasn't been seen for many years, our lake was down substantially as the irrigation district struggled to keep enough water in the lake due to the drought conditions and other factors. 
This photo reminds us of the sunset of this year's sailing season in most of Canada.  Perhaps now is a good time to start working on the boat and or trailer so that you are ready for next year.

My trusty trailer has served me well over the last 20 years and has over 60,000 kilometres on it.  The wooden box was not in the best condition, however after a bit of work it is better and weather proof too.


It doesn't take a lot of maker skills to add a reinforced vinyl top to keep the water out.  I can still walk on the deck and the vinyl and plywood top is removable so the trailer can be used like a typical open utility trailer. 
A proper hinged door has been upgraded at the back as well as a refreshing coat of paint.  Don't forget to check the lights and replace them if they are old. 
Wheels and tires need maintenance including bearing lube and tire replacement.  Check the coupler area and spring hanger welds as well for cracks.
The upper rack has been used to transport a second Seaspray in an upside down position from time to time.  This rack also has the potential to carry other items like bikes, sailboards, camping gear, solar panels, etc.  

This summer's (last weekend of July) catamaran clinic at Newell Sailing Club was well attended and the dominant catamaran was the Seaspray.  Since all of the attendees have sailing experience an afternoon of practice starts and short races was a popular activity.  Many new Seaspray sailors took part. 

A suggestion by one of the association members to attend a spring regatta at Wabamum Sailing Club is up for consideration.  The potential of having the Seaspray Nationals at this venue was also suggested.  A few comments regarding the normal inclement spring weather at Wabamum and the potential for a chance that Osoyoos may reconsider and host another September regatta in 2024 leaves this topic up for debate.  
We are also wondering if there will be any American events we could attend.   My own feelings on the subject of regattas is that our fleet needs it's own event without a lot of other boats to dodge as well as waiting for starts that may or may not occur in a typical multi-boat type regatta.  It may also be beneficial to our fleet to explore other ways to encourage newer Seaspray and other catamaran type sailors to take up a modified approach to competitive sailing.  
A goal of improving the sailing skills of your participants rather than stressing the competition may lead us to higher numbers of participants in a catamaran only event/regatta.  These modified events would be in addition to our normal competitive events.

I would like some more feedback from you and perhaps we can come up with firm dates for events for 2024 before the end of this year.

Take Control of Your Mainsail – Part 1 
Just like flaps on an airplane wing 
The traveler controls the angle of attack of the mainsail in much the same  way as hydraulic cylinders control the flaps on an airplane wing. When the  plane is going slowly and needs a lot of lift (e.g. to take off or land), the  flaps go down to make the wing more curved and more angled to the  oncoming wind. Similarly, when a boat needs to point higher, the traveler  goes to windward so the sail is in the middle of the boat. This makes the  entire sail plan more curved and generates lift and helm. 
When the plane wants to go fast, the flaps are retracted to make the wing  more streamlined and reduce drag. A boat is the same. When speed is the  goal, the traveler drops down so the mainsail is more in line with the  headsail. This minimizes drag and reduces windward helm so the boat  can go faster forward. 
When the traveler is pulled to windward so the boom is near centerline,  the leech of the sail ‘kicks’ the air flow to windward, creating a large side  force to leeward at the stern. This creates windward helm and makes the  bow turn to windward.
When the traveler is eased to leeward, the mainsail leech is more open.  This allows the air to flow more easily off the back of the sail. As a result,  there is less sideways force on the stern of the boat, and the driver feels  less windward helm. 
On almost every boat, it’s best to carry the boom near the centerline of  the boat when sailing upwind. This provides an optimal combination of  speed and pointing. In order to get the boom on centerline, you have to  position the traveler car to windward. If you leave the traveler in the  middle, it will be impossible to trim the mainsheet hard enough to get the  boom on centerline – and if you try to do this you will end up with way too  much leech tension. 
The goal is to use the mainsheet and traveler in concert to position the  boom near centerline and have the right amount of sheet tension (twist) at  the same time. In light air and/or chop you can’t trim the sheet very hard,  so the traveler has to be all the way to windward. As the wind increases 
and you can sheet harder, the traveler doesn’t have to be so high to keep  the boom centered. 
On some boats like this Sonar, it is actually fast to sail upwind with the  boom above centerline until you start to get overpowered. Play traveler or mainsheet? 
When you’re sailing upwind and you get an overpowering puff, it’s not  always clear how to depower. Should you ease the mainsheet so the  mainsail twists more and spills power primarily from the upper part of the  sail? Or should you keep the mainsheet tight and drop the traveler  instead, reducing the sail’s angle of attack and therefore the power it  produces? 
Here are some factors to consider when thinking about how to do this: Sea state – When you are sailing in bumpy water, the entire mainsail  moves around a lot relative to the wind. In these conditions, it’s critical to  be able to adjust the amount of twist in the sail, so play the mainsheet.  This gives you a better chance that at least some part of the main will be  at the right angle of attack each moment. When the water is flat, it’s OK to  sail with less twist and less adjustment of twist, so it often works well to  play the traveler. 
Boat type – Lighter, faster boats (e.g. skiffs and multihulls) tend to  perform better when they trim the main with a wider range of twist, so  they rely primarily on mainsheet. Heavier, slower boats typically sail with  less twist, and they don’t change the amount of twist as much, so they  can use the traveler more. 
Sail design – Mains with big roaches (typically with full-length battens at  the top) are very sensitive to small changes in twist, so it’s important to  play the mainsheet to change gears and keep the boat going fast.  Traditional sails with less roach are more suited for playing the traveler. Traveler system – Sometimes the choice of how to trim the main is  dictated by the layout of your boat. Is it easier to play the mainsheet or  traveler? Is it physically possible for the helmsperson to adjust both  quickly? Is there another crewmember who can play either one or both? Wind conditions – Occasionally the technique of trimming the main  needs to be changed to fit the wind. You may normally drop the traveler to  depower the boat in puffs, but if you have a day when the puffs are much  stronger than the lulls, will you be able to depower the boat enough using  just the traveler? Sometimes you need to play the mainsheet instead, or in  addition. 
Personal preference – In the end, the technique you choose for trimming  the main and adjusting its shape depends a lot on what makes you  comfortable and what you have found to work best in the past. My 
personal preference in most boats is to play the sheet as much as  possible. I adjust the traveler for upcoming trends in the wind velocity and  then use the sheet for small, quick changes.
