If it is not broken-don’t fix it.
We have on of the fastest growing classes in Australia and probably the only popular national class that can be easily owner built.
Why woul we want to change it?
I agree the foils are rubbish and the sails/rigging could be vastly improved but everyone has the same crappy set-up and that what makes the class good.I have never built a Sabre and I do not know the construction rules well. Yet.
Standard practice is to lay the glass in position, stategically pour the resin on to the glass and squeegee it over the entire area.1 coat only. Many layers of glass can be applied in one coat. A special cloth known commonly as peel ply can be layed over wet resin and peeled off when set to leave a suface that can be bonded or painted without sanding.
If you are new at this get someone with experience to help you. I am sure there will be Youtube videos on this subject also. Practice makes perfect.
Big tip. Get a large box of disposable Vinyl gloves like they use when preparing food. I would use a few pairs every job. Cardboard on the floor to catch drips and spills is a good idea too.
I don’t have a copy of the rules so the amendments aren’t much good to me at the moment. Going to wait until they are finalised before I purchase a set.
I am starting to think that boat weight isn’t critical. I am guessing but I think that extra weight gained by stiffening would be well offset by the performance gain. I am waiting for the new rules to be made available so I can get a copy and see what can be done in regard to this.
What’s a couple of kilos on the boat when I am carrying many extra kilos on myself? I reckon my poor down wind performance in the gusty nationals was a result of me being just over 90kg. I believe 75kg would be ideal weight. A couple of extra kilos on the boat seems insignificant when compared this way.I am getting confused about what is a composite boat. Composite would usually mean built from more than one type of material.
I see 4 main types of sabres
Plywood
Plywood fibreglass sheaved (most common type of ply construction)
Foam and fibreglass or foam sandwich as it is commonly known.
Foam and glass hull with plywood deck.
The last 3 could all be called composite. There is also timber and plain fibreglass boats but are not common in sabres.Which one are you lot referring to as composite?
Carbon doesn’t belong in sabres. Would probably be best to restrict the glass foam boat rules to bring them closer to ply boats.
Greg,
In my experience (which I admit is not a lot) scuppers would not achieve anything significant. Even after a capsize I have never had enough water in the boat to warrant it. The most water I have had in my boat was on a moderately tight windy reach and had forgotten to open the back Venturi. Even then I believe a scupper would not have removed any significant water even if I had have moved aft and hence slowed the boat down. I’d be all for scuppers if I thought the would do the job better than a Venturi.
For the record I am around 90 kg and have an on weight ply/glass boat. It may be different for different crew weights and different boat shape and weight.
I reckon I can notice the difference in boat speed if I leave the back Venturi open up wind. I find it necessary to have the forward Venturi open nearly always when the wind gets more than about 12 knots.
I see no reason to keep scuppers outlawed. I just do not think they are necessary.Craig
Hi “guest member”. I was not a the meeting but I was led to believe the same. This is the bit where we need to consult the sabre constitution to determine whether the rules were passed correctly. Where the hell is the constitution? It is one of those docs that is meant to readily available to every member.
I am not even sure if any of the new rules were passed. I have posted asking about this already.
CraigAt the current price of a new FRP Sabre hull I wold reckon I could get rich building them. I am even considering doing such. I would guess the builders would be making at least $4000 gross profit from a unfitted hull and could buid one a week. Add some foils and a few extras and make that $5k a week.
I ccould be wrong though. Once the new rulles are sorted and there is some stability I would guess some competition will bring the price down as long as they get a good set of rules and a “super boat” doesn’t spoil the whole Sabre show.Sabres are actually about building reasonably priced boats from ply. What we are trying to do here is accommodate glass boats in the rules and achieve the same thing. The only significant thing I have seen so far that glass boats do better is cost more. I do not think that second hand boats selling for over $15000 is what sabres are about.
I have nothing against glass boats. I have not owned a wood boat since my flying ant days. I am just concerned what the fibreglass boats could potentialy do to a class like this.
Obviously most of the guys spruiking glass boats in this thread already own one or get some finacial gain from glass boats. Correct me if I am wrong.Can any one justify the low maintainence arguement for a glass boat?
