Re: Genua Furler on Santorin...stay electrical or go mechanical

Hi Volker

So my santorin Nga Waka is a year younger launched in 1991 but it had sailed to nz from the med.....and it sat unused in Panama for a couple of years and on arrival in nz

I did a couple of cruises around NZ and some shorter transits in gales cause I wanted to see what bits of the boat might fail when stressed

First to fail were the gear boxes on the main mast. Both replaced with bonfiglioli gear boxes identical to those originally fitted. They were about Nz$300 each

The Genoa furler gear box also failed a couple of months later. It has a circular gear driven by a worm drive. I found a highly skilled gear maker (who had never seen a fibreglass gear box). He made new parts and assured me they would last another 30 years. Cost was about nz$2500 

The 12 volt motors that drive the furlers have been fully overhauled by specialists each costing about $1000. 

Since this work was done I’ve sailed through the pacific and down to the sub Antarctic islands. The Amel systems are brilliant to use and in my experience,  properly maintained, very reliable 

We did experience difficulty furling the main sail inside the mast when it would jam. That problem disappeared with a new sail

The other difficulty we had was the Perkins main engine. It was reliable but the cooling fresh water system was driven by a spline on top of the engine that slotted in to the back of the water pump. I did not know about a special realigning tool which is critical to reassembly ...... that cost me a couple of water pumps until I figured the problem. Later to ensure reliability I replaced the Perkins with a Volvo d250 Which is identical to the Perkins but has improved systems and less bits like water circulating systems hanging off it

I could go on but if you have any issues email me direct rather than clogging up everyone’s in boxes

Seasons greetings

Volker, 
A bit more. Championship gearboxes are available and relatively not expensive. Their motors are a straightforward rebuild by a good motor electrics specialist.
There are a number of parts on the Santorin that are the same as the bigger and heavier Super Maramu. The C drive is one and I'm pretty sure the curled gearbox is another. Therefore they are well over engineered for the smaller Santorin and should last and last.

There's nothing like your first sudden tropical squall to make you appreciate the Santorin's curling system!

Merry Christmas
