In Topic: Newer racing Multihulls

Eric e. Yes there's more than a bit of Newick in her - he knew about curves - and I loved every minute of sculpting/skinning the beam fairings out of extruded polystyrene. Nic Bailey (designer) also collaborated with Nigel Irens on several boats - so the Newick DNA is there for me right back through Irens' Gordano Goose and IT82... Isn't the love of aesthetic one of the main reasons we love multihulls, regardless of performance?

The current (short) alloy rig was originally from a Firebird more than 20 years ago and is more than capable of taking the extra righting moment. I know the Firebird designer whose engineering skill I rate very highly.

Regarding righting moment; She's 8.5M long by 7.5M wide. At my request we stole buoyancy from the aft end of the Amas and pushed it forward - making for a very safe "bow-up" attitude when pressing hard, possibly limiting the top speed with the extra drag of the aft beam and meaning max righting moment is only ever achieved in sheltered waters with the crew forward. Rudder winglets could be a possible future mod.

Back to the thread and other notable recent UK designs are from Darren Newton, mostly his Daz Cats, and Nick Barlow - his "Kittiwake" is a super looking boat!

Here's another pic of "So-What" being assembled

MTC 28. "So What". Launched late in 2010

Home built in vac-bagged Epoxy/Carbon/Airex. Empty weight about 500kgs. Mocra ready 820kgs.

Looks great! any sailing pics? Racing record so  far?

Thank you.

Here's some links:

I'm the builder/owner and have yet to race seriously but have enjoyed it so far - with a carbon rig and some "young guns" aboard, there is all to play for next season...

Regarding PP core - lookout for it at anything approaching a moderate temperature if it is under load because of the low Tg

Good (and I mean good) quality plywood is a perfectly legitimate material and much maligned in my opinion. Combined as directed in the plans with epoxy/glass it should yield a very nice boat at relatively low cost and low man-hours to build (for a one-off... )

Labour is the big problem when building low weight, high-stiffness multihulls in small numbers and sandwich structures are very "process-dependent". Plywood takes out a lot of that dependence.

It'll be here after I'm gone if well built...Build it and sail it before time defeats you dudes!

In Topic: How do you use your 'Trailable Multihull'?

If I could, I'd leave my MTC 28 in its cradle on a slipway to avoid anti-fouling it. Not a trailer-sailer, it dismantles in a few hours. 

On the mooring I've got some pontoons under the Amas which helps avoid anti-fouling them.Attached File  DSCF3540.jpg   29.74K   43 downloadsAttached File  IMG_1464 - Version 2.jpg   25.15K   46 downloads
