The fittings I had to change or plan to change on my boat are....
* Spinnaker halyard swivel cleat - cleat only from Ronstan to Harken.
* floating pully between spin halyard and tack line - currently Ronstan... Blew this pully up after modifing the system a bit. Fixed the problem and is now OK. We ran the same pully on the T for 4 years and had no trouble though.
* Spin sheet rachets from Holt which are crap..... both on the T and Capricorn we trie them and they blew up on the first outing each time. We now have Ronstan ones which did the job on the T and now the F-18. I believe Goodall supplies these now. Harken ones are better though.
* Spinnaker halyard and tack lines are absolute crap rope.... Replace these as soon as you get the new boat or ask Goodall to put some decent stuff on it. Likewise with the downhaul.
** All other ropes and fittings ar OK. Rudders are not too bad...... Just does not compare to a good Marstrom T. AHPC, I believe are using mostly Harken stuff on the boat now with some Ronstan here and there. Just let Goodall know you want your boat fitted out with Harken and you will have no problem.
