    I use the VHF aerial at the top of the mast with a Vesper splitter.  This deals with AIS/VHF/AMFM.  Works like a charm.  I did install the recommended aerial from Pacific Aerials.

    Ditto for me

    Thanks Sail Rock, good to know what sorta boat its good for.

    I'm not going to fit it to my boat.. , would you like a spare? make me an offer!

     

    Thanks but no thanks. I already have a spare fixed prop for emergencies.

    Yes, it is definitely a Henley. It is the same as mine (fitted on a Chico 30 and driven by a Yanmar 2GM20). I got it refurbished by Henley (in Glenfield) a few years ago - not cheap but much cheaper than buying a new Gori. It works fine, maybe not as efficient as a fixed prop but obviously less drag when sailing.

    If you do install it, you will need to use a stiff piece of steel flat bar to tighten the locking nut. Make sure this is tightened really well or else the prop might fall off when underway. This actually happened to us when reversing out of a marina berth - lucky place to be as easy / shallow to dive and retrieve it!

    or any good alternator shops in the Northern half of Auckland that could sort me out?

    GT Auto Electrix in Glenfield converted my N-type Hitachi alternator to run as a P-type with external charge controller. They were very knowledgeable and helpful.

    My advice: firstly learn to sail as crew with an experienced (and forgiving) skipper. As well as showing you the ropes he/she should be able to demonstrate sound judgement so that you can learn how to respond to the various challenges that the sea throws at you. 
    As a lifestyle, sailing is second to none - actually it becomes an obsession!

    Sealing Sheet Tracks

    Yes, no leaks since I reinstalled the Genoa tracks several years ago. I do this for all deck fittings. Occasionally a fitting has failed to completely seal so just have to remove and repeat.

    I did the same as Fish using Sika 291, the trick is too do the last tighten after it’s hardened but before it’s fully cured. And tighten the nuts not the screw of course

    Same here. Get someone to hold the screw in place with a screwdriver to prevent it turning and breaking its bond with the sealant, while you tighten the nut from below.

    Head, renew piping

    I replumbed my head and holding tank a couple of years ago with a combination of marine sanitary hose and domestic PVC waste pipes plus bends, elbows, etc. It works fine and no odours. I needed to use the rigid pipe on some sections due to tight spaces and bends that the sanitary hose couldn’t accommodate. The rigid pipes are well supported so there haven’t been any problems with movement or cracking.

    Nelson to bay of islands

    I did this trip a couple of years ago. First day going across to Cape Egmont was westerly 30+ knots and 4 out 5 of the crew were spewing our rings out! Next day it backed to SW and progressively moderated until we had to start motoring from roughly Hokianga. Then flat calm round the top and all the way back to Auckland.

    Lesson is what IT suggests: avoid being in a hurry and wait for the front edge of the high pressure system (but carry plenty fuel).

     

    Abandoned boats on moorings

    Agree. If you want to rent (i.e. occupy) a house you invariably have to pay a bond. The same principle applies to occupying a piece of the harbour. I am all for appropriate measures to force abandoned, derelict boats off moorings and marinas so as to release the much needed space for others to use. Question is how much should a bond be?

    I recently replaced my old compressor driven fridge with a 12V one from Fridgetech. It works a treat - nice cold beers! No longer have to spend $300+ every other season to regas. ????
