     Any boat will hobbyhorse in some conditions, and you can't always change course to get out of it.  Factors such as length compared to wave period, rocker, weight distribution, and longitudinal…Continue

Having an interest in trimarans also.....  The question of "wings" comes to mind with regard to the limited internal space in some Wharrams.  The Tangaroa in particular appears like it would be…Continue

My interest is in junk rigs, which have progressed a long way since James decided that they were unsuitable for Wharrams.   Instead of the flat junk rig that was pretty universal in those days, we…Continue

Interesting Pahi 35

Here is a Pahi 35 listed for sale in Aruba that is quite interesting.   it has a bridge deck cabin that seems to be integrated into the hulls.  It is completely lacking the visible beams projecting.  What confuses me is the listed beam of only 15'.... it should be around 18' I think.   Built in 1978 according to the add, it's a nice looking boat for $18K.  Anybody know anything about it?   Here's the URL:  Pahi…See More

Good Day,

How is everything with you, I picked interest on you after going through your short profile and deemed it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on:( mrsstellakhalil5888@gmail.com ) for the full details.

Have a nice day

Thanks God bless

Stella.

G'day Dean, unfortunatley this did not happen with the Teheni hulls. The project stood to long and got wet rot in the hulls. I am in the process of buying a new boat also in my picture albums ORO with a center cockpit, this has no mast so the intention is to Junk Rig her. As original plan. I will keep an eye out for your Build as well. Fair winds.
