The Measurer at Work…..!!

I’ve never been lucky enough to be present when any of my boats have been measured.  I’d love to see through the process to find out what’s involved.  The keel and the hull are done separately of course.

Hull Measurement 1David Williamson has kindly sent in a few photos of his new Ovington being measured in Australia.  (Writing this on the 29th, and the Ashes are a ghastly 4-0 ….)

Hull Measurement 2

 

Hopefully, in 2014 we’ll manage to get Keith Jamieson at BIFFA HQ to video some of the process for us all to take a look.

3130 – Check out the Hull too….!!

A couple of days ago we published some photos of the deck of Jordan Aspin’s 3130, now in these two shots you can check out the reflections of the “Bluebird K7” Hull colour!  It looks to me as if this is on top of a white keel – nice!!!  ( I note too that Jordan’s workshop is a wee bit cleaner and tidier than my garage !!)

Hull Compression Dents….

Do you sail off a jetty?  If you do, then it is quite likely that down one side of your hull you have a row of tiny little compression dents.  Just bumps against the jetty do that….

Phil Tinsley was telling us that quite often heat will pop them back out again. He went as far as to suggest an iron on a cloth to encourage them back into their intended curve.

Very interesting – must check with Brett….

FF Trailer Supports……

I have a rather old laminated  Flying 15 which I removed the keel from to repair as it was getting quite rusty.  I then noticed that the hull was buckled slightly inwards just aft of the keel.  This has now been repaired by cutting out and scarfing in plywood, and careful work with fibreglass cloth and epoxy resin.

However when I come to fit the keel and hull back in the trailer it is quite clear that it was never properly fitted in the first place.

I notice that a lot of the English boats do not have supports under the hull, but rest on the keel, on the support near the bow and with side supports on the upper part of the top sides.

I also see that one of the websites which supplies English flying 15 trailers, does not recommend hull supports at all, describing them as spinnaker guy and sheet tanglers.

Do you have any recommendations or experience to comment on whether I should use supports under the bilge of the boat as was done previously considering it has an older and more delicate laminated hull?

What I propose doing is bolting the hull to the keel,  and then modifying the trailer until it fits.  Fortunately I have an overhead electric hoist so I can lift both the keel through its centre of gravity (where I have a large shackle temporally fitted) and partially support the boat at the same time by the strop going around the hull and through the shackle.

This will make getting it fitted to the trailer relatively simple as I can keep raising and lowering it until I have everything right.

But it would be much simpler if I do not have to put hull supports under the bilges.

I would appreciate a brief comment from you as to whether you think I should use the bilge supports.

More on Carbon Fibre Fifteens… from Charles….

The Ovi carbon boat is carbon on the inside and iI dont think it is vacuumed on. The problem has been the hulls have come out only 9kg underweight. Therefore to wet the carbon out they had put 11kg more resin in the inside laminate. The new boats may be better.
As a comparison the boat Gavin built for me was 20.9kg under weight – it has carbon both sides of the hull and the underside of the deck. He charged me £500 for all three layers of carbon pre-preg.
The carbon layer inside will make the boat retain its stiffness a lot longer, so it is a good investment.
Carbon cloth is fiddle to fit and a lot more difficult to wet out, that is why it is easier to use pre-preg, which fits dry into the mould than manually do a manual wet out – that it why Ovi has to charge more.
