Brilliant Vic, you are a ripper but where can you go from here to top that?? ...maybe a sub is still on the horizon!!

How about bringing it up here to Shark Bay for trials and have a look at our whopping great Tiger Sharks to model a sub on?....wok

Thanks guys. I am not real happy with the weight of the mast about 18kg. I think I will build a foam one sometime next year.
I will build a lighter boom to. The yacht weights 118kg.I would like to get it back to around 110kg. Looking forward to Lefroy.

Can not do a dam thing at the moment, rain and wind blowing at 50kph plus for the last couple of day's and does not look good for the next week, need to get the sail on and set up the blocks. To dam windy get the mast of so that I can get the yacht out of the weather.

Now have to work out where to put everything for a 800k road trip to Lefroy. The trailer is full with 3 class5 and a mini. Class3 will fit on the roof rack plus 1 more mini.

Just keep stacking them up, Vic.
We will give you a hand to unload and tick them all off your manifest on arrival.

Obviously You need to build a couple more then, seems like You could build taller racks and stack them. Assuming, of course, they are painted black...............

Help.
I am about to start getting the final materials for a foam mast. The only aluminium that I can find in 1/2in square or round is t5 will this fit the purpose?

you could make a webbed timber spar , which would work fine, dont forget that spot that needs reinforcing. have you chatted with makers of scaling down bars as some I ahve seen are T6 round

I got to sail the class3, The wind was light but I was more than happy the way it went, The steering was excellent and could not believe how smooth the ride was. Due to lack of wind and racing commitments I did not get to sail it again on the weekend. During the weekend the mast cracked between the hound and base. (the reason we think is that the yacht was on its side with sail on and the mast facing the wind. There would have been a lot of down pressure on the mast when the wind became gusty and strong.) The mast can be repaired and strengthened in the area of failure and next time I will either take the sail of or use crazy wheels.

I parked my yacht on it's side for years, and in Europe this is required at 99% of regattas. I have done this in up to 35 knots of wind with no issues ever. There has to be a reason, but your method of parking is not the reason. Sorry.

1/2" square T5 would be fine, and you do get more bonding. Wet sand the alloy with glue as a way to break the oxide layer. Messy but it works. About 80 grit.

Vic. I checked out the CASE dealership and the 1/2" solid square alloy they were using to join the draper mats on header fronts, was fatigue cracking through the bolt holes, so they have progressed to steel 12mm x 12mm x 2mm RHS.
Sorry but no joy.

Thanks Chook

Kiwi on closer inspection the timber in the area of the crack was very thin. I think it requires a couple more layers of glass between the hound and base .I will also take a strip of timber out and fit a stronger internal cross web from the hound to the base. I will also run a 65mm wide carbon fibre tape from top to bottom of the mast at the thickest area of the mast. After that I will start on the foam mast, the t5 ali only comes in 5m lengths how do I cover the top 1m of the mast or does it matter
Cheers


Thanks for the pics Chook

I would have thought the timber was really only the former on which the glass is layed. Cedar has bugger all compressive strength. If the mast is hollow, this failure is likely because the sides of what is effectively a tube are getting closer together. In real terms, it just ain't stiff enough. (Now when did I last hear that :) )

I had a web up the centre of the mast, I did not anticipate the strength required (lesson learnt) I am going to replace that web with a thicker one by removing a strip the length of the mast and install it. Use a couple more layers of glass and a carbon strip and hopefully that will give me a much stronger/stiffer mast.
