Anyway, To what I was really on here to post about with regards to twin extensions. No one has it. Just too much hassle on such a wee boat.the guys with the Aft sheeting either have the rudder hung of the transom or on a rudder gantry.

Thats enough of me for now, Any questions just ask!

Hey Luke,

Thanks heaps for the great post. Lots of interesting stuff there, and good info on what the fleet is doing with their cockpit layouts. I find the mid cockpit sheeting a pain to have to go around the back of, but on balance I reckon it's probably the lesser of two evils (and flicking the tiller extension around the back of the boat would have to be a lot less prone to foul ups than trying to take it forward through the cockpit I reckon (but then I've only tried it out the back, having mid boom sheeting).

I'd love to know what sort of construction you finally settled on for your toe rails. My boat *desperately* needs something grippy in the cockpit floor (I have *nothing*). Upwind is ok as I use the centreboard to push off - though the further downwind I go the trickier it can get to get out on the trapeze (though a toe or two put carefully at the base of the mainsheet block on the cockpit floor is usually enough to step out onto the wire). I've gone and put a swivel cleat on the main (finally), so using it as a foothold isn't as practical as it used to be.

The pattern of rails you've put in your boat looks perfect to me (a couple down the front two-thirds of the cockpit and then some diagonally in the rear quarters). How did you build them in the end?

For those who might be interested I'll stick a few pics up of my boat in the next post ...

Okay, since we're sharing stories of boats - here's mine. I bought it from a guy on the Goldcoast who I gather had kept it sitting around in his backyard for the best part of 15 years (I think he was only the second owner in it's 30 year life).

It needed some new timber around the centreboard slot, and a new mast step - but with those done I could take it sailing.


Here she is in December 2010, after one of my first outings. The original "grip" on the gunwhales was next to useless (I had quite a time of it slipping around), and I found the clamcleats on the vang let go all the time (plastic clamcleats are pretty well always useless). So I decided to use the traveller cam cleats for the vang and put the traveller into the mainsheet cleats (sacrificing being able to cleat the main). Problem solved, and no more swims downwind because the vang suddenly let go!



For those curious, here are the foils - which I gather are probably the original bruce farr design? (any 3.7 historians out there care to comment?)



And here we are a year later with a new beach trolley (woohoo!).


Cockpit layout - tennis ball makes a passable toe-hold for getting out onto the wire. Original hiking straps on the boat useless, but I was mangaging ok without them (who on earth thought hiking straps flush with the deck and in a recess would be a good idea?)


2012 and I've found some spare change to have a cover made up. No more scrubbing green slime off the deck after each lot of summer rain! Have also taken a leaf out of the Contender class's books and added a Highfield lever to the forestay. It's nice to be able to let the rig tension off / pull it on before going out in a second. I'm lucky enough to work from home, so when the wind is good I like to be able to dash down to the sailing club, rig up in less than 20 minutes and be on the water. Anything that takes some time out of rigging is a good investment I reckon :)

After the vang finally pulled a saddle out of the cockpit floor I found myself with a little bit of repairwork to do - so I made a week of it at home and fixed the hiking strap issues, added a bag to stash stuff in (waterbottle, halyard, radio), had bigger inspection ports put in, and finally re-varnished the foils and timber around the centreboard case (*ugh* I hate varnishing ... but wooden boat bits are pretty).


Since then I've also stuck one of those fandangled swivel cleat bases on the mainsheet - so I can actually use the traveller upwind! I'm also *hoping* my tacks will improve, now that I can cleat the main and have both hands free for the tiller and grabbing the trap handle / hooking on. Time will tell!

Photo above shows current layout. I've put the traveller back through the cleats meant for it, and the old mainsheet deck cleats now hold the vang (which is the control I tend to spend the most time fiddling with - other than the main of course).

Now to do something about some sort of toe-rails! I get by without them, but things can be a bit less than graceful!

Wow great stuff! 

The boat looks like one of the original glass ones with the tread pattern all over the foredeck...

Its a little bit odd seeing a traveler on a 3.7.. no days we all just use a fixed rope bridal in the middle of the boat.. I think the travelers went out a few years ago when there was really no need for them, But some days when its light id really like to be able to twist the main but still have the boom centered.... Ohwell! 

With regards to foils, I does look like someone has played around with them and are not the original design, I Think i have the original design centerboard and rudder at the moment, i might be wrong though. I am surprised to see them just made out of wood... are they heavy? 

That cover you have for the boat is really nice! If only...  Also your beach trolley is really nice, I think im due a new one soon, so might take yours into consideration! 

With regards to toe rails, mine are just made out of glass, standard boat cloth weave, 300g i think? And just layed up I think around 6 layers with the west system epoxy... overall, they are about 2mm thick... 
I just started out with a cardboard template them made a wooden mould for each of them, The covered the whole lot in packing take so i could get them off when finished! the rear ones are two separate rails that have been glassed together to make one.  

If i could do them again, I would certainly make them out of carbon and Vacuum bag them to get the extra strength... They do take quiet a beating up!  Mine are completely glassed to the floor. 

It looks abit like you have some sort of rails on the boat already, but they do look very low, Before you go ahead on making anything flash, Try getting some of the foam grip and laying it on and see how they go, The grip can raise the overall height up by a couple of mm's so they might be just high enough. 

When I started off in the boat, I didnt have any, Like you, I found going upwind I could push of the C/Board, But anything other than that was a mission! 

Any other questions out there lurking that you would like to be answered?  Smile

Luke

Any boat builders out there could give advice on fitting gunwhales ?
I'm getting close to this point on the Farr build. I'm splicing lengths of 22mm sq Maple that will become the gunwhales, and will likely steam them prior to fitting, but don't want to use any fixings so am pondering how to clamp them in place.
I'm also unsure whether to do any chamfering/shaping before glueing.
I'd thought about using upright battens every few feet up from the floor, on both sides of the boat,spanish windlassed to each other across the deck to clamp the gunwhales . Anyone have a better idea. ?
