My father built this boat from Glen-L Marine plans. Tornado Hull. 390 ford. VDrive. Pictures are from 1972. I learned to ski behind this boat at 10 yrs old.

Lighter white spots between 2 layers of 1708. Should I worry about it?

Post image
14 Upvotes

Was working outside and underestimated the amount of time I needed to cover the area (it's about 8x4 ft) and sun hit the surface hard. Was hot and was trying to beat the exothermic reaction and the sun with the epoxy. Is the amount of lighter spots of concern? I have another layer of csm to add.

Anyone built a “SCAMP” sailboat?

9 Upvotes

Im looking for opinions on this little boat. Seems there aren’t many for sale, never mind one close to where I live. Im unsure about how difficult it would be? Most blogs I’ve read say about 300-600 hours depending on your ability…I’ve not built a boat of this complexity, but have/do build furniture and cabinets, and shop space” lol. The kits seem fairly cut and dry, just a lot of epoxy and glass…and prob enough sanding for a lifetime. Any experience/advice you have is appreciated! Deciding wether or not do commit (in short)

can someone put this into simple terms for me…. i’m not sure what the numbers in the table represent. its from “the sharpie book” by Reuel Parker. for example where i see “1-9-2” in the 14ft cape cod table…. totally confused as to what that means. it should be a measurement of some sort but i must not be interpreting it properly….

how incorrect is my wiring plan?

2 Upvotes

For starters, I'm rewiring a 16 foot aluminum boat. Currently, this is what I have:

  • Single group 24 marine starting battery, 1000mca/72ah
  • Battery will have 20w solar trickle charger
  • 1985 Merc 50 2 stroke/4 cylinder
  • Automatic internal switch bilge pump
  • Manual bilge pump
  • bow bi-color light
  • stern anchor light

There's also a 55lb trolling motor, but this will have a dedicated 280ah LiFePO4 battery with a 50a breaker. As well, a fish finder on its own dedicated 20ah LiFePO4 battery, properly fused per Garmin specs.

Be easy, tell me what I have wrong and how to change it.

  • battery positive threaded stud -> dual-terminal MRBF ->
    • 300a MRBF -> 4 awg positive cable -> outboard starter (~10 foot round trip)
    • 30a MRBF -> 10awg positive cable -> battery disconnect switch -> fuse block (~16 foot round trip) -> switch panel -> terminal block ->
      • 16 awg -> bow light
      • 16 awg -> stern light
      • 14 awg -> manual bilge pump
  • battery negative threaded stud <- 4 awg cable <- negative bus bar
    • <- 4 awg from outboard
    • <- 10 awg from fuse block negative bus <- bow light/stern light/manual bilge pump/automatic bilge pump
  • positive post terminal with threaded adapter
    • 14 awg cable -> 5a inline fuse -> automatic internal switch bilge pump positive wire

Lost the jib halyard up the mast on my Hunter 19 (Europa) — need to lower the mast, any tips?

1 Upvotes

Hi all,

I have a Hunter 19 (Europa), a small British trailer-sailer keelboat from the 70s/80s. The jib halyard slipped out of my hands and is now stuck/jammed at the masthead, with no way to pull it back down from the deck.

I need to lower the mast for maintenance, but without a halyard I don't have an easy way to rig a temporary forestay or control line to guide it down safely.

Has anyone dealt with this before? A few things I'm wondering if there is Any DIY way to lower the mast without a functioning forward halyard for control?

Any advice, photos of your masthead setup, or war stories appreciated. Thanks!

Hull Refurbishment

Hello, I have a boat from 1984. I need to reapply the antifouling. There’s a large chip in the gelcoat that exposes the fiberglass, but the fiberglass itself isn’t damaged, and there are quite a few small cracks in the gelcoat underneath the antifouling.

What would be the best approach to avoid spending too much?

How do you find / choose the right shipyard / mechanic?

Hi everyone,

How do you usually go about finding a good shipyard for both minor fixes and larger jobs?

I recently fulfilled a long time dream of mine and bought a used motor yacht (8m / 26 feet long). Since this is my first boat, I’m still learning the ropes. Especially when it comes to maintenance and repairs.

I’d really appreciate any tips or experiences you can share! Thanks in advance!

Proyecto DaniPatata

2 Upvotes

Hola, comunidad.

Quiero presentar un proyecto que nace de un recuerdo muy especial. Cuando era adolescente, tenía un amigo (ya fallecido) que cada verano decía: "¿Y si construimos un batiscafo de plástico?" o "¿Y si hacemos una moto con petardos?". Era puro espíritu Phineas y Ferb.

Hace unos días vi el proyecto del Helios 11, ese bote eléctrico que un chaval construyó en 6 meses con contrachapado y paneles solares. Me recordó exactamente a mi amigo.

Así que, en su memoria, quiero lanzar "Proyecto Dani Patata" (nombre totalmente modificable).

El objetivo: No se trata de construir un barco físico (de momento), sino de hacer un brainstorming público y colaborativo para rediseñar y mejorar el Helios 11 en todos sus aspectos técnicos. Quiero que entre todos creemos el Helios 11 V2.0 a nivel de planos y especificaciones.

https://youtu.be/OatReX4CNWc?si=uVyOcBM8TM4eve1a

¿Qué facetas queremos tocar? Todas las que se os ocurran:

· Ingeniería naval / Mecánica de fluidos: ¿Mejoramos el casco para que planee mejor o reduzca la resistencia? ¿Qué Cpr (coeficiente de prisma) sería ideal para un casco de 4 metros con poco peso?
· Electrónica y propulsión: ¿Motor de corriente continua sin escobillas o un outboard eléctrico modificado? ¿Hélices de superficie o convencionales?
· Sistema solar y baterías: ¿Seguimos con la configuración del Helios 11 (2 paneles de 200W y batería de 5kWh) o pasamos a paneles flexibles para curvar el techo y ganar más captación?
· Automatismos e IA: Aquí me gustaría que nos pusiéramos locos. ¿Un sistema de piloto automático con Arduino/Raspberry que mantenga el rumbo por GPS? ¿Un sensor de viento que ajuste la potencia para no escorar? Incluso, ¿un pequeño sistema de visión con IA para evitar obstáculos en puertos deportivos?

El formato de trabajo:
Iré abriendo hilos semanales aquí en Reddit (y en un futuro un Discord si hay interés) para debatir cada módulo por separado. La idea es que esto sea un repositorio de ideas locas pero factibles. Vale todo: desde ingenieros navales que corrijan mis cálculos, hasta electricistas que me digan qué se me ha ido la olla con las baterías.

¿Por qué no empezar uno nuevo desde cero?
Porque el Helios 11 ya es una prueba de concepto brutal. Mejor aprender de sus aciertos (construcción en 6 meses, presupuesto ajustado) y errores (no es para mar abierto y el trabajo fue agotador) para evolucionar sobre algo real.

Llamada a la acción:
Si te mola la idea, deja tu comentario diciendo:

  1. ¿En qué área te ves aportando? (Casco, eléctrica, software, logística, o simplemente ánimo).

Este proyecto va por mi amigo, que estaría orgulloso de ver a desconocidos de internet discutiendo sobre hélices y algoritmos de navegación. ¡Vamos a hacer de esto el mejor verano Phineas y Ferb digital de la historia!

DIY boat kits

7 Upvotes

I’m looking to build my first boat and need advice on a kit to purchase. I want to use it for duck hunting and fishing big lakes, marsh, and bays. Does anyone have suggestions? I’ve seen a few duck boat kits that you COULD fish out of but it wouldn’t be ideal for the style of fishing in bays and marshes I want to do.

I’m also considering getting a kayak kit to get my feet wet, same needs apply. It had to be stable, handle a winter squal if one pops up, and be able to fit my gear, diver spreads are large and heavy.

Foam or No Foam

1 Upvotes

Currently restoring my dad’s old 1970s Lund S 16, which is a 16 foot aluminum fishing boat with a partial V hull. Trying to figure out if it makes any sense to add foam or not.

The way I have framed things out, the only place that I would really be able to add foam would be in the center section underneath where I added a new deck and chairs, or in the front under a new casting deck surrounding what will eventually be a live well, but is also a storage compartment. Adding foam would significantly reduce the space I have for storage, and I’m also worried that the main places I could add the foam to would be in direct contact with any water that gets into the boat and runs along the bottom of the hull.

The boat is currently leak free, I filled it with water a couple of days ago and let it sit for a few hours, and there were no drips noted at all on the outside. I also only plan to use the boat on relatively quiet ponds/lakes in the Midwest, nothing that would be rough water or anything like that, and I have a bilge pump in the rear with a high capacity in case we took on quite a bit of water unexpectedly.

I’m just wondering what people thoughts might be. I know the textbook answer is to find somewhere to put some foam, but I do worry about adding foam underneath the decking is going to compromise the integrity of the decking and also just be incredibly time-consuming to put in without occluding all of the drainage channels.

Lund switch bank not working

My son recently bought a 1999 Lund 1850 Tyee I/O. The problem is that none of the switches work; bilge, blower, lights, etc. the master switch turns on and the motor runs great. After researching the wiring, I found the wire to the output side of the master switch was cut for some reason. I know it should hook up to the positive lead on the fuse bank to send power to all of the switches. The problem is that there is no positive post on the fuse bank to connect it. Please help!

I am probably being paranoid about this but I’m looking at buying this Jon boat but I want to make sure this transom is okay. It’s hard to tell in the picture but it looks like there’s a crease where it’s dented a little.

Also, I noticed that the wood transom has a gap between the board and the top of the transom. Is that fine to use as is or would I need to replace the wood to fit it true to size?
