    hi all. Very useful forum you have here. Thanks!

    My interest in the modified Crowther in the below link is growing.

    Unfortunately the information on the modifications is slim on the ground and the boat is 500 miles from me so I can’t easily go for a look.

    https://www.boatsales.com.au/boats/...-5634932?pageSource=details&id=SSE-AD-5634932

    Does anyone have any information on this boat or care to comment on it at all?

    Thanks
    Jamie

    The modifications are sensible ones and the boat looks fairly clean but 125 is a lot of money for one of those. Scruffy C10s can be had about $35k. I'd probably look for a multihull specialist surveyor on the sunny coast to run an eyeball over it, but it'd need to be immaculate at that price.

    That is a nice looking cat. I notice looking around on line that 'C10 Crowther' seems to cover a bunch of quite different looking boats. Just wondering if anyone can give a potted history of the development of this design???

    It's not simple. I looked at them for years and got a few clues from people better acquainted with them.

    Designed originally by Lock Crowther they were built in victoria by the same people responsible earlier for the bolwell cars under the name beach marine.

    There is a 7.5 hull sometimes stretched to 9 and the 10 meter hull. I think there were bigger ones aswell.

    So the 7.5 came as a bridgedeck cabin version and open deck. Most I have seen have centerboards.

    The 10 meter could have boards or LAR keels. All I have seen are 7 meters wide with the typical slim crowther hulls. They have a pod under the bridgedeck to carry an outboard.

    So now you come to decks.

    There is an opendeck, a bridgedeck cabin with 4'6" clearance then seemingly a bit later a bridgedeck cabin with standing headroom. The 80s boats have the square styling. Then in the early 90's someone got hold of the molds and designed more rounded decks for them.

    In all cases I have seen on the 10s the aft cabin extends inward over the bridgedeck giving a double each side. So even the open decks have 2 doubles and usually a single forward with an enclosed head forward in the other hull. Typically a galley one side and a chart room other side amidships. Standing headroom.

    They come up cheap pretty regularly and I really like them. Not how you'd design or build a cat these days but for the era a very good design.

    I'll look for the brochure but here is a thread worth reading. Some variation in various accounts of what happened.

    Hi Guzzi, thanks for the summary and links. Do you have a boat currently or still looking? No sailing for me this winter, the tri is out of the water for a few minor jobs and other routine maintenance.

    In theory I'm building a modified wizzer, but life keeps getting in the way. I thought I was getting better but last month my body had other ideas.

    I need to be clear about this so pardon the convoluted explanation.

    I was convinced the boat I wanted to build was a demountable Sango. I gave Mr Woods some money and he sent me both Sango and Wizzer plans.

    These boats as designed are straightforward to build and excellent, but to translate Sango from strip/ply to foam brings some complications. Because I was only going to sleep in the middle cabin anyway it became less appealing. So open deck and a tent. Basically Wizzer. But I want headroom so now I'm working on increasing the freeboard and adding a cabin and getting the lines right. Unfortunately hullform doesn't work anymore. Only 9P seems to be around now and I can't get it to run on this computer, so I'm currently trying to learn how to drive deftship which IMO isn't as easy. It probably has more features but controlling curvature is not yet clear to me. I might have a copy of 9S (or earlier) on a backup somewhere but I haven't found it.

    What work are you doing on the tri ?

    You could build a demountable Gypsy without the cuddy - there is a round bilge version - which would give you headroom without the re=design. Sometimes there are too many options :)
    The tri is having a bit of an interior tidy, relashing of nets and bum paint - all those fun things.....

    (and apologies to the OP for the thread drift).......

    Guzzis3, I worked for Bolwell in Mordiallic in Melbourne in the ‘80’s, they had a set of moulds in the yard which I believe was the Eureka but that’s it. Pretty sure Beach Marine was in NSW and not related.

    Oh Ok. I thought I read an account somewhere by one of the Bolwells about beachmarine, but I may be wrong. Sometimes I forget why I entered the room...

    Jamez, Gypsy (1800 kg) is twice the weight of skua (1100kg), which is twice the weight of eagle or wizzer (650 kg). Well not quite but you get the idea.

    Gypsy would get lighter in foam and no cuddy of course, but it never ceases to amaze me how fast boats get heavier when just a little longer, wider, higher...elf is the boat I would like to build but the molds are in germany and Mr Woods quite correctly has opted not to compete with that builder.

    I am not concerned about chined vs round bilge, I have always liked the looks of sango that's all. Beautiful boat. There is a version of Skua with higher freeboard and longer cabin. I assume that boat has 6' headroom although I have not seen that stated anywhere. I think the origional design had about 5'4" headroom but it's not hard to get 6' on a 30' boat.

    Mr Woods has allowed me to change designs once, I don't know that I want to push my luck for a second shift. :D

    I am glad the tri has not developed any problems.
