Today Danny and I finished the mainfoil locking struts more or less. I then played with mainfoil flap and with the help of Eric put a carbon reinforced gudegon on the side of the rudder boxes so I can cut a slot and insert a heim joint for the rudder cross linking tubes

Also a little work on the main foils hinges and flap . I had to glue an extra 3x 4 mm on fir on to the flap fairing to fill in the gap . This then needed reshaping rather carefully to fit with very little clearance .

Weekend of fabricating and watching Danny tig weld. Ss torpedo for the trailer to support the keel bulb . And the ss hinging struts to lock down the main T foils . He has welded unp the struts but I need to clean up the threads for the heim joints .

Ah a return to Blue Arrow . I have an F18 HT bimare which I have retrofitted with exploder A3 foils multi purchase foil adjust and T rudders . Works a little scarey at speed downhill!! Only problem with the electric rams are their speed amperage demands . How are you sensing height

What sort of cat is your ram control on. And what are you using as mainfoils ??

Hi Lars. your rudder control looks interesting . Mine is very simple 4 :1 purchase to pull the end of the rudder back in the slider . This will be lead forward to the traveller fixed block where I have a spare sheave thru a cam cleat then across and back to the other rudder box . This way I...

I had a pleasant package from upfront. My Kaver 0.9 furler. Really nice !! I made a fixed eye carbon filament wound prod attachment just beyond the sheave box which will deflect the bobstay. And yet another Bakelite special I made a double sheave angled turning block which will sit on the...
