    Help Identifying Old 420 Class Boat

    Did they drill hull numbers into the forward side of the transom on i420's like they did for 5O5's? Your rudder is in fabulous shape.

    Hiking when there is no water

    Sometimes, though this model is not double-ended like a proa...

    Hiking when there is no water

    Excellent. On a tangent (snicker), when I mow, I use a tacking lawnmower (electric) and have gotten pretty adept at throwing the extension cord to windward. Still need to work on the gybes though...

    420 better self bailing cockpit ideas?

    I forgot to mention that, for the bernoulli bailer not to leak, the hose would have to pass above the waterline at any heel.

    420 better self bailing cockpit ideas?

    Hi spiritwolf. Ignoring class regs in this comment... A while ago I was wondering about "bernoulli bailers" sometimes found on vintage wooden power boats and RC scale models... The principle seems similar to the Elvstrom bailers but it looks like they might be less prone to leaking. A critical bit might be to find where to position suction. It should be where the hydrodynamic flow is fastest on the hull... (near the widest part of the CB?) obviously this changes on tacks/gybes. Another wonder would be is whether a dinghy can ever reach a velocity where they would be truly effective. (image below: shamelessly pillaged from "Pipe for manual draining in pits" would be analagous to the transom flaps on your dinghy.

    Just a caveat... you may get unexpected results

    Maybe referring to the unmanned boats?

    When your crew is lightweight, one must take certain measures.

    The 2018 Golden Globe Race

    [Mark #2] "Before start we discussed many options, among the skippers, what to do to deal with storm situations. Throwing warps over board and trawl heavy stuff and so. To keep the stern in the wind and break waves before they reach you. Well, I thought a lot and pondered these problems. But I quickly saw the boat wasn’t behaving in a sound way with that stuff behind the boat. So I decided halfway the storm to pull the 200 meter lines and everything back on board. That was much better! ... I will never ever again drag lines or anything for that matter, behind the boat whilst being in a storm. ..." The idea of dragging gear to break waves might work in theory if the period and amplitude of the waves were less than the size of the gear -- to say this was not the case in those conditions would be an understatement.

    What Not to do on a Dinghy

    Not a dinghy -- but if the link above didn't work for you try this.

    Shouldn't matter -- so long it qualifies for content on the "Dinghy" forum

    From Cats to Dinghies...Hopefully.

    Well, what about a Lightning? Designed for three, but known to be sailed single-handed on occasion.
