Re: Steel vs Fiberglass

Damn. The fabric weight was one of the factors I was most interested in :). The skin thickness is a critical element.

We cannot compare different models if we don't have some of these basic...

Re: Steel vs Fiberglass

It is K&M, a Dutch yard.

This a photograph I too at their yard. I think it is a large Dykstra designed Bestevaer under construction.

Re: My boat was boarded (and messed with) at anchor!

I think that is an optical rather than a laser rangefinder.

The advantage of the laser models is they will give a distance readout without any knowledge of the size of the object.

Re: 1989 Hunter 40 - A million questions.

A big danger with the electrical system is shorting out large cables. These carry enough current to start fires.

One of the first things I would do is secure those large cables with some cable...

Re: Steel vs Fiberglass

Nice designs Bob.
I have seen the other two, but not the first white boat. Any details?

Sorry for the thread hijack, but aluminium is a bit between fibreglass and steel. So perhaps it is not a...

Re: Fortress Anchor--Does anyone set it to the 45 degree mud angle?

The 45 degree setting gives the highest holding power in very soft substrates. It is important to realise that if you try and use the 45 degree setting in a substrate that is firmer, the anchor will...

Re: A Dragon in the anchorage

The chain is often fed to the mast by an channel in the roof, so the deck is not effected and need not be a flush design. On aluminium yachts that most commonly feature this arrangment (Boreal,...

Re: A Dragon in the anchorage

Re: A Dragon in the anchorage

Retractable bow sprits and anchors are becoming more common. Here you can see the bowsprit in carbon fibre. The whole anchor and bowsprit folds back when not in use. Very high tech, but a bit flimsy...

Re: Rocna vs. CQR dimensions

Technology has fortunately moved on since the 1930's when the CQR was developed.

Yes, many of us managed for a long time, but these days there are much better alternatives.

Re: True and Apparent Wind Question

There is a lot of misunderstanding about true wind. True wind is the wind referenced to water. If there is current this will influence true wind. It is not the wind you would feel while stationary.

Re: Anti-fouling paint under the keel

I think we are all in agreement that applying antifouling paint just before water immersion is not ideal. The paint manufacturers make this clear.

The important question is "Is it satisfactory?"

Re: Problems Sizing Ground Tackle for 50' , high windage cat

3/8 G7 is stronger than 1/2 G30 or BBB chain and a little weaker than 1/2 G40 HT chain. With G7 chain the normal procedure is for the chain maker to incorporate a larger link on each end. So...

Re: Problems Sizing Ground Tackle for 50' , high windage cat

Well, I was simply answering the OP's question. :)

He obviously feels chain with a WL of 5400 lb is inadequate. The 3/8 G30 BBB you are recomending usually has a listed WL of 2650 lbs

I don't...

Re: Problems Sizing Ground Tackle for 50' , high windage cat

You can get G7 chain which is considerably stronger than G4. G7 has WL of 6600 lb in 3/8 size. I think it available in the same link size as regular HT but check. I use metric 10mm G7.
