pirate Re: Catamaran capsize.

Its has been posted and someone speculated its a Wharram.. methinks its maybe a modified homebuild or something based on Wharrams ideas.
Stern is wrong for a Tiki and bow is wrong for the other style.
To much decking and failure to reef in time can do that.

Re: Catamaran capsize.

Admittedly, I know little about catamarans, but if the water came in through an open hatch, I don't see why having one hull full of water would flip the whole boat over. I don't understand why it went over so fast (he said less than one minute), and then floated so high. I would have thought he could safely bail it, but that's not how he said it happened. Can anyone explain this for me? Thanks in advance.

pirate Re: Catamaran capsize.

With Wharrams its best to have the fore hatches clamped down.. on my Tiki 21/26 I fitted the rubber bonnet catches one used on minis (original) to hold them down tight, also used draught extruder to make it watertight.
The main hatch design is crap so I did the same with the forward half of the folding hatch.
My Tiki 26 (plastic commercial build) on a sail back from France in a F7 had waves sweeping the hulls (full sail doing upto 16kts).. closing the UK coast I noticed a strange surging movement to the boat and thought some of the beam lashings had come loose but when I checked they were all fine.
As it had quietened down I opened the hatch to make a coffee and saw the hull half full.. same when I checked the other side.. the surging sensation was the water riding back and forwards as I rode the waves.
If he had flooded one hull that would have helped flip the boat if he had full sail up.. wind getting under all that decking would have finished the job.
Wharrams are very stable, light and hard to capsize but with the right combination can be flipped.
If it was just the forward hatch that caused it its unlikely a Wharram.. theres a watertight bulkhead.

A 29 year old American sailor was rescued off the east coast of Austrailia. He had sailed the 23ft catamaran the last three years in Aus.

Re: Catamaran capsize.

Not a whisper of this anywhere else. I wonder if he knows the position where he left it, and if he's going to try and get some cats together to try and right his boat?

Cats get their righting moments from bouyancy .
Flood the leeward hull and the righting moment is greatly refuced.

Re: Catamaran capsize.

My Wharram tiki 31 had four compartments in each hull by memory, you couldn't fill the entire hull.

I had the port center compartment full once, didn't flow to the rest.

Ahaha.. The Hinemoa is the old heavy design from the 70's and a narrower beam than the later stitch n glue Tikis if memory serves.

Thanks for that link. There were some surprisingly high quality builds being documented on that site. I lost a couple hours perving.

Re: Catamaran capsize.

Yep, people sometimes have a one sided view of Wharrams, but there are also some very nice high quality ones around too, as well as some still not terrible but more simple versions that are getting people out cruising.

Sometimes it's not what you have but how you use it

A few of my favourites (not all high quality boats):

Tiki 38 Lucky Fish (world cruiser)
https://www.youtube.com/channel/UCkH...cqUOkQZqkelyPg

Tiki 38 Pilgrim (atlantic crossing - boat is sailed hard & fast in the Med too)
https://www.youtube.com/channel/UCZj...PzCoe8QjiXMcOw

Pahi 53 Hecate (professionally built charter boat - one of the very best)
Search on Google and YouTube

Spirit of Gaia (the big daddy)
Google search Pahi 63 to see other versions too

Tangaroa 37 Sailing Tangaroa (basic but awesome cruising in WA)
https://www.youtube.com/channel/UCsL...c__xcEh0QbcUKg

Tiki 26 Catamaran Ariki (budget summer cruising on a little boat in the Adriatic)
https://www.youtube.com/user/MatjazChvatal/featured

Tangaroa 35 Sailing 2 Canoes (not a quality boat, and maybe what comes to mind for many people when they hear 'Wharram' - wild, feral even... - but they do amazing cruising in the Bahamas with small kids, dogs, and video quality that is some of the best that I have seen - what a life for these kids)
https://www.youtube.com/channel/UCZj...PzCoe8QjiXMcOw

There are many more but these came quickly to mind. Sorry for derailing the thread a little

Yup

But I'm sure some people would be horrified at the thought of this type of 'cruising'...
