There are some folks who believe in an end plate effect so they like to seal the lower edge of sails against the deck.

 

Which only works if the sail is actually touching the deck. If there's 30 cm clearance, might just as well make it 90. 

Agree re: endplate effectiveness, but there is also the consideration of the distribution of area in a type of boat that is very RM limited - nice and low and you have plenty of drive with minimal RM penalty.

Hi Bruno,
A large dead rise angle on a pure planing hull will increase drag and improve comfort.
What we are talking about here is comparing to a traditional semi displacement round bilge form, I.e how you get from the keel to a chine that necessarily needs to be above static waterline most of the time - ie to reduce the curvature in the transverse sections (as well as reducing rocker f/a, all in the name of reducing dynamic squat) then you have to have a deadrise.
14 spends maybe 60% in semi displacement the rest in planing depending on where you sail.
Trick is to be good at semi and planing work, with some conflicting demands!

...a proud moment ^^...................congrats Dan!

 

                          ...I love the drama as he's putting his gloves on!

 

 

 

...a couple of things I noticed **.....

..........there was a couple of times that I noticed one or another control line was madly oscillating near the mast -----is there any way you might rectify this?  :mellow:

 

...and that gybe,,where the end of boom hit the water --who's going to buy a boat that does this??  :o

 

 

 

.......**,,,,a testimony to 'BB'  

The wobbling rope is the halyard tail (below the lock) which is tidied on an elastic - could tie it tighter. Or tape it.

I would say that any boat worth sailing will finish a light or medium gybe with a splash of boom end in the water. Old laser habits die hard. Could be easily remedied by rolling less or over sheeting or some such.

11.032 inches, or 280mm in metric speak, if memory serves.

Shaw 4 seems like it is being sold by the builder to recoup costs. Agree that it sadly is only worth what somebody will pay, and custom dinghies are bloody expensive and don't have a lot of value for many people. Probs quite a lot of decent gear on it that could be recycled mind.
