Keep in mind that you need a special tool to open them.
Otherwise they work quite nice.

I am working in Photovoltaik business, normaly you can open MC4 without special tool.
This are very good plugs and are really industry proofed.

I have been using three of these. One for each phase wire. I have XT150 bullet connectors soldered onto each end of all three phases. You just plug in each bullet connector and then slide these over and tighten down the glands on either side. Very nice quality and have been bone dry. Having to disconnect each phase wire individually is a little bit of a pain I guess but I don’t remove those wires too often.

Good solutions but where do you have space for these connectors ? In the board on top of the mast plate? Make a hole for space to store the big connectors?

I’m still using the same since build #1. They’re bulky, not even close to practical when it comes to attach/detach mast and board (I never store the mast on the board), I dug a recess under the mast but with those the cables are longer and I zip tie the 3 connectors on the back of the board, out of water wen planning. The ensemble looks all but professional… but whatever.

Here is the first (and latest) generation of Duotone hollow carbon mast. Light, strong, waterproof with plenty of volume for 3 or 4 connectors close to the mast plate… You will notice the soft joint on top. It is a speed kitefoil mast. Looking forward to see that principle adapted to efoils since the mast part that needs to be large to resist to the highest strains is the top part where we also need volume for our connectors.

Any test or sample ones for sale?

Just google “Duotone daytona”. The complete hydrofoil is sold 3000€ or 3600USD 😢 I don’t think that this mast exists as a spare part. Therefore the idea to DiY one see below.
> **[Daytona 105](https://www.duotonesports.com/en/products/daytona-105-44900-3509)**
This mast is part of the Duotone Daytona race foil:
Mast: 1.05m long, 2.39kg. A 90cm one would weight around 2.0kg. Not bad.

Using 10-15 layers of fabrics, It should be possible for a skilled DiYer to make such a monolithic mast in one shot, either around a mold that looks like this mast + vacuum/infusion or inside a 2-part hollow mold plus a compression bladder.
Other possible building technique: [New build from 3D printed molds (very low cost, but high performance !) - Builds - FOIL.zone](https://efoil.builders/t/new-build-from-3d-printed-molds-very-low-cost-but-high-performance/6031?u=soefoil)

Shatem brand m25 2/3 pin connectors seem to be the best, only 10€ from Alibaba 50 amps

I don’t have a datasheet for these connectors, I think they are rated for 80 -90 amperes.
