It’s almost Father’s Day, so hand the laptop over to the Dad in your household. This post is for him.
The “nice wolf” (a.k.a. husband) has been requesting that I post about jetties for months. He has a boat obsession to rival my house obsession. (Okay, slight exaggeration.) One of the reasons that we bought our block on the canal is that my husband would like to be a sailor. At the age of 7, he sailed with his parents, from Darwin (N.T.) to Paris and ever since he’s dreamt of boats. Our particular part of the canal is catamaran friendly. There are no bridges between our canal and the sea. Ultimately, (read “retirement goal”,) my husband would like a catamaran large enough to sail the family around the top half of Australia, but for the near future he’ll be very happy with a little motor vessel that can fit an esky, a few crab pots and the three little pigs.
So let’s talk jetties….
Fixed or floating? L shaped, T shaped, finger shaped, land-backed? Wood or steel?
Advantages of fixed jetties:
- Cheaper than floating (to be confirmed.)
- Good looking.
- No movement = less opportunities to go wrong???
- Won’t tilt with heavy loads.
Advantages of floating jetties:
- Easy to board/load boats regardless of the tide.
- Easy to moor boat.
- Less strain on lines and cleats.
- Won’t submerge during storm surges.
- Partly transferrable, for example, if you move up the street or give up boating and decide to sell the jetty.
Note: tidal variation in Mandurah is less than 0.75m.
You can tell I’m flailing here. My research into the pros and cons of floating and fixed jetties has mostly lead me to other parts of the world that either have much greater tidal variation or are exposed to stormy weather. Neither have I been able to establish likely costs. I sent a few email queries, but I think jetty builders are old-fashioned telephone types!
These options and jetty size limits are taken from “Jetties and Moorings” by the City of Mandurah. Some shapes offer greater mooring flexibility than others. For example, once you’ve moored a big boat on the land-backed jetty, you’re not going to be able to accommodate anything else.
Our mooring envelope looks like this:
So Boaties! We need help. Which jetty type do you think is best for mooring a 40ft catamaran in the Mandurah canals? It should also allow access for a couple of surf-skis or maybe the boat of friends, dropping by for dinner. What do you think it might cost? Throw a ball-park figure at me, we are starting from scratch.
(Edit: News just in! I did get a reply from a company specialising in floating jetties. First rough guess, with a few variables, the most obvious being size, is $40-50K.)
And for those you who might be less concerned about the boat, how does this tickle your fancy?
